Drafting a provisional application is often the first step in the road to obtaining a patent. However, due to time or budget constraints, provisional applications are often not afforded the attention that they deserve, resulting in applications that lack the necessary disclosure to support the later-filed non provisional or utility application. When this happens, potentially invalidating prior art that otherwise would have been precluded from the prosecution process by the provisional applications’s filing date could all of a sudden be used to impede patentability. This is becoming increasing true in today’s climate where courts and patent examiners are honing in on the Section 112 written description requirement against addition of new matter and demanding more support from patent applications.
While it is always best to draft thorough and complete provisional applications with all the necessary disclosure, sometimes that is not possible. When experiments are not fully completed, time is short, and budgets are tight, it is still possible to put together a provisional application that can be relied on. Below are several “must haves” when it comes to putting together a provisional application.
1. Start with the claims. While claims are not required for a provisional patent application, they nevertheless form the basis of the patent application and are ultimately what describe the invention. When drafting the claims, think about the various ideas that are part of the invention. If you have a composition, you may also have a method of making the composition or a method of using that composition, as well as kit claims, and even system claims. The claims do not have to be perfect, but they should at least cover the features of the invention. Drafting a set of claims will help put the invention into perspective and help focus the rest of the invention. There is no limit placed on the number of pages or the number of claims in a provisional application. Thus, if possible and if time permits, add more claims than may be necessary just to be sure each element and combination is captured somewhere.
2. Use the claims to outline the specification. Once the claims are drafted, use them as an outline to draft the specification. If they are complete, the claims should form a good basis for what needs to be included in the specification. Each different claim type can be the basis of a different section of the detailed description.
3. Whenever possible, include experimental data. Experiments provide support that shows that the invention does what it claims it does, i.e. that it is enabled. You cannot assert that a composition can be used to treat cancer without at least providing some experimental data to that effect. If no experiments have yet been conducted, hypothetical examples describing the future experiments could be included, but care must be taken to clearly reflect the fact these theoretical examples are prophetic and were not actually conducted.
4. Provide supporting figures, graphs, charts, data tables, schematics, and/or sequence listings whenever possible. Any supporting information should be included and described. This information should be easy to gather and provides further support for the invention. Even a power point slide presentation or figures from a recent draft of a scientific publication can form a good basis upon which to draft the remainder of the application and should be submitted with the application if no formal drawings are available.
5. To the extent that time and budget permits, fully describe the components of the claims. The purpose of a patent application is to fully describe every possible feature of an invention. Often times the patent application not only describes the features of the preferred embodiment but also numerous variations of each feature and potential work-arounds that competition could use to skirt around any issues patent. In a CAR T cell therapy application, for instance, not only is the preferred binder described, but other possible binders are described as well. This type of drafting protects not only the invention, but also modifications to it. If time is limited, however, focus should be given to adequately describing the preferred embodiments and essential or most critical features.
6. Provide proper definitions. A definition section should be included to define the various terms, especially those recited in the claims. The definition section should not be overlooked because it can provide important basis for claim interpretation and scope. Often times, certain terms, such as terms of art, in the definition section can be copied over from a similar application so including these should not be too time consuming.
7. Include a background section. The background section can be used to put the invention in perspective and in some cases even steer the application to a preferred art unit within the USPTO. It does not need to be long (it can be as short as two sentences), but it should describe the current state of the art and most importantly the problem that the invention intends to solve. By providing a background, the invention and its contribution can be better understood and appreciated.
8. Draft an abstract. Abstracts are limited to 150 words. Often times drafting an abstract before or after the claims can help crystallize the drafting process. If you can summarize the major gist or themes of the invention story into an abstract of 150 words or less, it shows you have a good grasp of the key parts of the invention upon which the claims should be based.
In today’s climate with courts and examiners requiring more and more proof of support of conception and reduction to practice, i.e. possession of the claimed invention, provisional applications need to include enough information to satisfy the Section 112 written description requirement and to avoid running afoul of new matter issues when using them as the basis of a non-provisional utility application. By focusing on the above seven points, inventors can improve the likelihood that their provisional applications will overcome the written description hurdle.
Provisional patent applications can be a valuable tool for inventors. Such an application serves as a “place holder” for a later-filed nonprovisional (or utility) application. While inventors often debate the need to file a provisional application, filing a provisional application rather than going straight to a nonprovisional has several benefits.
1. Provisional applications establish a priority date. While it is not examined by the USPTO, a provisional application allows the researcher to establish a priority date for an invention that predates subsequent prior art from impeding patentability. One year after filing the provisional application, the researcher must file a nonprovisional application, which claims the benefit of the provisional filing, to maintain patent rights. If the one-year deadline is missed, patent rights that may have been afforded to inventions described in the provisional application as of the filing or priority date are lost and new prior art can be introduced.
To benefit from the filing date of a provisional, however, that provisional must adequately support and enable the subject matter claimed in the nonprovisional application. Simply put, the nonprovisional application can only claim the benefit of the provisional application’s filing date and disclosure if it supports the invention. This forms the basis of the 35 U.S.C. Section 112 written description requirement. How much support is required is a subject of constant debate but recent case law suggests that courts are becoming more strict on interpreting written description. Inventors are thus better off including more description in their provisional applications to maximize their chances of having their priority dates upheld. Failing to do so increases the risk that prior art disclosed after the priority date can impede patentability.
2. Provisional applications help buy you time. Provisional applications require only a minimal fee to be filed ($280 for large entity, $140 for small entity, and $70 for micro entity) and they provide a twelve-month window before the more costly utility and PCT applications need to be filed. During this window, inventors can find financing and generate more experiments to support the utility and PCT filings.
3. Provisional applications are not public. This means that a provisional patent application can be abandoned before the one-year mark and the information in that provisional will not become public. This is helpful, for instance, if an inventor has an idea but cannot generate enough data within that one year to support that idea. In those situations, the inventor could abandon the provisional and refile it when the necessary information is gathered.
4. Provisional applications can be updated with new information. From the time the first provisional application is filed to the one-year deadline of filing the nonprovisional application, the inventor can file multiple follow-on provisional applications to add data or information to that application. If the first provisional was filed only with hypothetical examples, follow-on applications can be filed with actual results of those examples. When filing follow-on applications, however, inventors should be mindful of having adequate support as discussed in the first point.
Provisional patent applications provide value benefits to inventors, such as establishing early priority dates and allowing the inventor time to either update the invention with follow-on applications or abandon it entirely without making it public. Careful attention, however, must be paid to making sure that the provisional application has sufficient disclosure in it so that a later-filed nonprovisional can benefit from its filing date.
On May 29, 2020 the World Health Organization (WHO) officially launched the COVID-19 Technology Access Pool (C-TAP), an initiative which is intended to improve access to existing and new medical technologies, such as therapeutics and vaccines, which are developed in response to the global COVID-19 pandemic.
According to the WHO, the technology pool is meant to ensure better access to existing and new COVID-19 health products through five elements:
1.public disclosure of gene sequences and data;
2.transparent clinical trial publications;
3.funding agreement clauses on availability and trial data publication;
4.promoting the licensing of related technologies to the UN’s Medicines Patent Pool (MPP); and
5.promoting open innovation models and technology transfer.
But what exactly are patent pools? And how to they work to improve access to patented treatments? In this post, we will examine patent pools and the advantages and disadvantages that they provide.
Another potential mechanism to improve the patent system is to address the hurdle to drug development created by overly broad patents. Overly broad patents are those, for example, which are directed to a drug that targets multiple indications, yet only one of those indications is actually being pursued by the patent holder. By referencing multiple indications in the patent application, the patent holder is blocking others from being able to pursue those indications. Faced with either paying the high costs of licensing or being sued for infringement, many potentially lifesaving technologies may never be developed.
The problem presented by overly broad patents can be solved by creating patent pools. A patent pool is an agreement between two or more parties to combine their patents into a single package, or pool. When members of the pool combine their relevant patents together, they can divide the patent rights amongst themselves so that each party takes exclusive or non-exclusive rights to a particular invention covered by the combined patents. Members divide their patent rights along with a promise not to sue one another and without the exchange of licensing fees. This allows each party to the agreement to practice its invention without worrying about the threat of infringement or licensing fees.
If the pool includes all relevant patents, the pool can serve as a platform for freedom to operate within that patent landscape. The pool further stimulates innovation by giving its members the opportunity to use technology generated by the industry to bring new products to market and to carry out further reach and development.
History of Patent Pools
Patent pools have been around for more than a century. One of the original patent pools was created in 1856 for the sewing machine industry. Prior to the creation of the patent pool, sewing machine manufacturers Grover, Baker, Singer, Wheeler, and Wilson were accusing each other of patent infringement. To settle their lawsuits, they all met in Albany, New York. At the meeting, Orlando B. Potter, a lawyer and president of the Grover and Baker Company, proposed that each company pool their patents together instead of spending their money on the infringement suits.
Another example of a patent pool was in the early 1990s, when the US government mandated a patent pool for aircraft manufacturing. The need for increased aircraft production arose during the onset of World War I, however, manufacturers of aircraft were faced with threats of infringement and high royalty charges from the relevant patent holders in the area, namely the Wright Brothers and Glenn Curtiss. The government realized that more planes were needed to assist in the war effort and required the creation of a patent pool. This pool ultimate resulted in the formation of the Manufacturers Aircraft Association.
While patent pools have long been established in other technological areas, patent pools within the pharmaceutical industry are relatively new. In 2008, the World Health Organization (WHO) recognized the important role that patent pools may play in increasing access to drugs. As a result, attempts to establish a patent pool for severe acute respiratory syndrome (SARS) and for neglected tropical diseases have been made. In July 2010, the Medicines Patent Pool was established to foster the development of HIV/AIDS drugs. The Medicines Patent Pool solicits voluntary licenses from patent owners of antiretroviral medicines to create a pooled resource. This pooled resource can then be accessed by drug manufacturers to develop new and adapted formulations of drug products, such as heat-stable products, lower-dose formulations, pediatric medicines and fixed-dose combinations, that will be sold in developing countries.
Advantages of a Patent Pool
A patent pool may be beneficial for all the parties involved, including the drug manufacturers, the patent holders, and the people receiving the treatment. For drug manufacturers, for instance, a patent pool eliminates the uncertainty and expense of negotiating licenses where several different patent holders may hold rights to a single drug or treatment. It also encourages further research by lowering the cost associated with licensing technology to create new medicines.
For patent holders, on the other hand, the patent pool offers the opportunity to enjoy royalty streams from different sources and provides a collaborative platform for enhancing access in developing countries. Since the drugs that are developed as a result of the pool are limited to developing countries, the pool would not affect the patent holders’ rights in higher-income markets. Accordingly, patent holders would be able to continue selling the rights to their drugs and treatment at higher prices in developed markets.
For people living with HIV/AIDS, most importantly, the patent pool would make medicine more affordable. It is estimated that the Medicines Patent Pool could impact an estimated 33.3 million people living with HIV/AIDS.
Patent pools offer several other advantages for members of the pool. First, they can help overcome blocking patents. If all the relevant patents are combined in the pool, then there are no outstanding patents that can act to block the use of those patents.
Second, patent pools can reduce the overall transaction costs associated with the patents by lowering licensing fees and reducing patent infringement suits. They do so by allowing licensees to negotiate with only one party, eliminating the need for potential licensees to conduct their own patent landscape analysis, and eliminating problems associated with royalty stacking. Since patent pools allow members of the pool to use the technology without being sued for patent infringement, patent pools can reduce and even eliminate patent litigation settlements.
Third, patent pools allow intellectual property other than patents to be included in the pool. This is especially important because it allows the inclusion of trade secrets that may be important to the research and development behind the products.
Finally, patent pools further allow members of the pools to share in the risk of developing the technology. By spreading the risk across all members of the pool, no one company is solely responsible for putting in all the time, effort and money in developing a product.
Disadvantages of a Patent Pool
While there are definite advantages to patent pools, there are also several disadvantages to them. One of these disadvantages is the uncertain return on investment that can be generated. Pharmaceutical products are costly to develop, and when companies invest a significant amount of time and money into developing technology that ultimately becomes part of the patent pool, they expect a return on their investment. However, that return will have to be shared amongst the other members of the pool. Determining exactly how the member companies divide the return will be complicated and may depend on a variety of factors, such as a company’s contribution to the initial technology and to the final product, will need to be considered.
Second, patent pools may actually shield invalid patents from being invalidated in court. By protecting invalid patents, patent pools may require that royalties are paid on a technology that would be part of the public domain if the patents were actually litigated in court. This concern could be alleviated if all candidate patents to the pool are reviewed and examined by an impartial expert to determine their validity.
Finally, patent pools may create some antitrust issues by eliminating competition through collusion and price fixing. Companies that are not members of the pool may be at a competitive disadvantage since they will not be able to obtain the necessary licenses to develop a product. Since companies will not have access to the necessary technology, these companies may struggle to prosper.
Patent pools strive to solve the problem of balancing innovation of new drugs and access for all. Companies that are members of the pool would, in theory, benefit because they could develop new therapies.
Chimeric antigen receptor, or CAR, T cell therapies use the body’s own T cells to fight off cancers. The development of such cellular immunotherapies is becoming increasingly popular technology for treating cancer. Novartis’ Kymriah and Kite’s Yescarta are currently the only two FDA approved therapies on the market but many other companies are looking to launch products in this highly lucrative and therapeutically promising field.
Despite the promising nature of cellular therapeutics, however, CAR T cell therapeutics present some unique IP challenges that should be resolved early on in the development process in order to minimize hurdles when it comes to commercialization. Here we discuss some of these unique challenges specifically when it comes to seeking a freedom to operate, of FTO.
1. Highly crowded landscape. The patent landscape for cellular immunotherapies is highly crowded with many actors already established in the space. CARs involve several different components. The current generation of CARs involve a binding domain, a transmembrane domain, a signaling domain, and at least one co-stimulatory domain. Companies already have their own proprietary CARs with modifications to any of these domains. The two FDA approved products are both directed to CD19, for instance, and many other groups are working on CD19 as well.
2. Multiple components. Since CAR T cell therapies involve multiple components, each of which will require its own separate FTO. As mentioned above, CARs involve a binding domain, a transmembrane domain, a signaling domain, and one or more co-stimulatory domains. To effectively launch a product without infringing a third party’s patent, each element of the CAR must have a clear FTO. Even one third party patent with claims covering any one of the CAR elements could subject the company to infringement litigation.
3. Method patents. Methods of manufacturing CAR T cell therapies should not be overlooked. While composition claims are often the most favored, there is significant value to patenting methods related to engineering the CAR T cells, or culturing and expanding them. Companies that develop CAR T cells may run afoul of the method claims even though the composition of the CAR T cell itself is different. Therefore, it is not only important to analyze patents directed to each of the components, but also to any methods that can be used to manufacture the cells.
4. Global nature. CAR T cell therapies, by their very nature, may require certain steps of the process to be carried out in different countries. For instance, the current generation of CAR T cells use autologous cells, meaning that the cells that are used and modified are those taken directly from the patient. Once they are taken from the patient, they can be transported to a lab in a different location, even a different country, for modification. The extraction, modification, and subsequent re-administration can thus happen in different jurisdictions. An FTO, therefore, should not only be limited to the country in which the therapy is going to be commercialized, but also in the countries in which individual steps of the process will be carried out.
Due to their complex nature, CAR T cell therapies present unique obstacles to commercialization. Companies developing products in this space need to be aware of these challenges early on in the development process so that they can take the proper actions (e.g., seek licenses, design around existing patents, challenge existing patents, etc.) to minimize their risk of commercialization.
Strong patents are the foundation of any valuable patent portfolio. In my latest book, Billion Dollar Patents, I explore ways to draft patents and build strong patent that will not only provide products with a competitive edge but that will also be upheld should they be challenged in a post-grant proceeding.
Drafting strong patents is equally important in today’s pandemic climate. We have seen many companies and universities devote significant resources to COVID-19 research in hopes of developing a vaccine or cure for the disease.
With so many companies working to develop a cure, companies are rushing to patent their innovations. Despite this rush to the patent office, it is important to still follow best practices when filing applications. Below are five strategies when it comes to filing COVID-19 related inventions.
1. File quickly
The U.S. and other countries have a first-to-file patent system. Accordingly, it is important to file patent applications quickly before your competitor does. If you file an application even a day after a competitor does, you likely lose all rights to that invention.
Despite the rush to file, it is important to understand that the pandemic does not suspend patent laws. Accordingly, patent applications must still satisfy the various requirements of patent law, especially written description and enablement, in order to have a defendable priority date. This means that to actually benefit from the filing date of the application and predate competitors, that patent application will need to have sufficient information and data to support the claims.
Generally speaking, the more information and the more data you provide in an application, the better chances you will have to end up with strong claims. Problems may arise, however, when you do not have enough data because experiments are still in progress. In these situations, it is still important to file patent applications early using hypothetical examples. While hypothetical examples are viewed differently across jurisdictions, they may provide a viable alternative when experimental data is not available.
2. File Often
Not only is it important to file early, it is also important to file often. This is particularly true when experimental data is not immediately available as discussed above. It is important to remember that you are not limited to filing just one provisional patent application. You can file as many as you want during the course of the year and then merge them together to file one utility or non-provisional application. In these situations, you could file new provisional applications as soon as new data becomes available.
One caveat to be aware of is that the new data will only provide priority to the date on which it was filed. Unless it was supported by adequate disclosure, such as a hypothetical example, it will likely not benefit from any earlier provisional filing dates. This makes it even more important to file updated provisional applications as often as possible.
In addition to covering new data, the patent applications should cover work arounds and foreseeable new developments to the invention. Patents provide a value in create barriers to market entry and “excluding” others from your field. By filing applications to modifications, you can expand your footprint in the market.
3. Take advantage of USPTO’s accelerated program
The USPTO is currently offering an accelerated program for COVID-19 related technologies, called the COVID-19 Prioritized Examination Pilot Program (May 14, 2020). It is applicable to any product or process related to COVID-19 that requires FDA approval such as INDs, IDEs, NDAs, BLAs, PMAs, and EUAs.
To submit a patent application under this program, that patent application must be limited to 4 independent claims or 30 claims in total. Only small or micro entities can apply for this accelerated pathway and only 500 cases will be permitted in total. As part of the program, the USPTO hopes to reach final deposition with 1 year and possibly within 6 months.
By taking advantage of the USPTO’s accelerated program, companies can expedite the process by which they can obtain patent protection for their products.
4. Conduct quick FTO studies
As previously mentioned, the coronavirus pandemic does not suspend patent laws. Companies therefore still need to be aware of potentially blocking third party patents that may present hurdles to commercialization. Such patents can be identified with a freedom to operate (FTO) study. This is particularly true when companies are using pre-existing drugs, such as Gileads’ antiviral, Remdesivir.
Even when the process is rushed, conducting FTO studies during the course of development is important to identifying potential roadblocks to commercialization. This allows companies to proactively seek licenses or workarounds to their inventions.
5. Prepare for compulsory licensing situations
We are in uncharted territories. While only a handful of countries have ever issued a compulsory license, which would allow a country to circumvent a patent to manufacture and distribute a patent protected drug to its public, companies need to prepare for the possibility that this could happen. Earlier in March, Israel issued a compulsory license to AbbVie’s HIV treatment Kaletra® for use to treat COVID-19. It is likely that more countries will employ similar measures depending on what drug will prove effective to treat the disease.
To put themselves in the best possible situation, companies need to proactively think about how compulsory licensing could be used for their products and better prepare themselves for dealing with that possibility.
While the need to find a treatment or a cure for COVID-19 has created a rush to patent coronavirus technologies, companies in this space should be mindful of following existing patent laws as well as being aware of the new opportunities afforded to them.
Whether it’s the current pandemic or simply a change in business needs, there are many reasons why a signed agreement may no longer serve the interests of a party. So, what can a company do when it finds that it is party to an agreement that no longer serves its interests? The answer is simple – it can renegotiate the agreement.
This answer may surprise many because people generally think that once an agreement is signed, it is final. In fact, renegotiating agreements is definitely possible, and it is a strategy I have successfully used on multiple occasions.
This strategy should, however, be used with caution. Time should be taken to properly negotiate agreements upfront to avoid the hassle of having to renegotiate later. Nevertheless, there are situations requiring agreements to be renegotiated.
Excessive financial burden
One reason for renegotiating an agreement is when one party is unable to meet the financial costs of an agreement. License agreements are one example where this can come up, but they are certainly not the only ones. Since license agreements often call for a number of different payments—including annual maintenance payments, reimbursement of patent prosecution expenses, milestone payments, and royalty payments—financial obligations on licensees can be immense. Luckily, with so many different possible areas for payment, restructuring payments such that they are more on the backend is often enough to help a cash-strapped licensee.
Change in business needs
Another reason for renegotiating an agreement is when one party is unwilling to meet the financial costs of an agreement, given its current needs and plans. In this scenario, the party is able to pay, but it might not make business sense to do so.
For instance, I worked on another license agreement in which the licensee changed directions in its development plan, and the licensed product was no longer the primary focus of the company. To the licensee, the license was a “nice to have” rather than a “must have.” Since having the license continue was more favorable than terminating it, the licensor was able and willing to agree to lesser financial terms.
By renegotiating the financial terms, the licensor was able to keep its financial stream alive, and the licensee was able to reduce its business expenses.
Unable to meet milestones
Another reason to renegotiate agreements is when parties are unable to meet agreed-upon milestones. This situation occurs in a variety of agreements, including license, research collaboration, and clinical trial agreements. What generally happens is that one party cannot meet the milestones set out in the agreement, and the parties must come together to revise the original agreement, assuming they want to keep it alive.
For example, in a license agreement, the development of a licensed product might have moved slower than expected, so the parties can agree to delay initiation of a phase I clinical trial and any associated milestone payments beyond the originally agreed upon date.
By renegotiating milestones, associated timelines, and costs, both parties can maintain an agreement without running afoul of its terms.
Poorly drafted original agreement
A final reason for renegotiating is when the original agreement is poorly drafted, which may create unnecessary confusion about a party’s obligations, place unintended obligations and/or liabilities on a party, or generate additional burdens for a party.
To illustrate this last point, I was involved in renegotiating a license agreement in which royalty payments to the licensor were not based on revenue generated by a licensed product but on revenue generated by the entire company. This meant the licensor would benefit from its licensed product as well as all of the products and services sold by the licensee company. As written, this agreement was unfair and likely not what was ever intended by the parties. Nevertheless, such language made it into the final executed version and was something with which we had to deal and amend.
Assuming both parties want to continue working toward the objective of the original agreement, renegotiating is an effective way to keep a relationship going while making its terms acceptable to both parties. When faced with the possibility of one party walking away and terminating an agreement, it is often in the interest of both parties to come together to find mutually agreed upon terms under which both are willing to continue.
Understanding the Differences Between Patentability and FTO Using Wuhan's Patent Application for COVID-19
Wuhan Institute of Virology filed a patent application at the Chinese patent office on the use of Gilead’s Remdesivir for treating COVID-19 on January 21, 2020. The patent application raises questions of how could Wuhan file a patent application to something (in this case, a drug) that does not belong to them.
Many people have a difficult time understanding how a third-party can patent something using a product belonging to someone else. To understand why this is the case, you must first understand that a patent is a negative right -- it is not a positive right. As such, a patent does not allow the owner to make, use, offer to sell, or sell the invention. A patent merely allows the owner to prevent others from doing the same. There may be other patents or regulatory hurdles blocking the patent owner from actually making or using his own product. In other words, just because you get a patent, does not mean that you can actually commercialize your product.
There is a difference between patenting a product and having freedom to operate (FTO) to use that product. I’ve discussed the differences between patentability and FTO in previous posts, but here I will discuss it using Wuhan’s patent application to using Remdesivir for treating COVID-19 as an example.
Gildead’s Patents for Remdesivir
Gilead has several patents covering its antiviral drug, Remdesivir. For the purposes of this post, I will only examine two.
Gilead filed U.S. patent application number 14/613,719 on February 4, 2015 which claimed priority to U.S. Provisional Patent Application Number 61/366,609 filed on July 22, 2010. This application issued on September 4, 2018 as U.S. Patent Number 10,065,958 (the ‘958 patent) with independent claim 1 broadly directed to the composition as follows:
1.A compound that is
Gilead also filed U.S. patent application 16/265,016 (the ‘016 patent application) on February 1, 2019 which claims priority to U.S. Provisional Patent Application Number 62/219,302, filed on September 16, 2015, and U.S. Provisional Patent Application Number 62/239,696, filed on October 9, 2015. This application was allowed on February 6, 2020, with claims specifically directed to a method for treating a coronavirus infection in a human with Remdesivir.
Patentability of Wuhan’s Patent Application for COVID-19
The patentability of Wuhan’s patent application for COVID-19 will turn on whether the application satisfies the requirements of patentability in the country that it is seeking the patent. These include i) novelty, ii) inventive step/obviousness, and iii) written description and enablement.
The patent application has a good chance of satisfying the novelty requirement since COVID-19 is a novel coronavirus and Gilead’s patents do not specifically mention COVID-19.
Likewise, written description will likely be satisfied assuming the patent application was filed with the necessary data and descriptions.
The main hurdle to patentability will be inventiveness, or obviousness. Since Gilead’s patent specifically mentions using Remdesivir to treat viral infections caused by a Coronaviridae virus, the patent office could reject the claims because, arguably, it could have been obvious to one skilled in the art to use Remdesivir for any coronavirus, including COVID-19. To overcome this rejection, Wuhan will need to show that there is something unique or unexpected in its treatment methods, whether it is the dose, the dosing regimen, or even the safety profile.
Overall, obtaining a patent will not be automatic for Wuhan but it is certainly possible that they will receive a patent with claims narrowly tailored to treating COVID-19.
Freedom to Operate (FTO)
Assuming Wuhan is able to receive a patent, the next question is whether it will be able to market or sell the treatment. This comes down to whether or not Wuhan has freedom to operate, or FTO. As the name implies, this analysis requires determining whether there are any blocking patents in the geographic region in which you plan to commercialize (i.e., make, sell, distribute, use, and otherwise market) the indicated therapy. That is, in order to determine whether or not Wuhan can commercialize the COVID-19 therapy, you have to see whether that therapy falls within the scope of any third-party patent rights within the jurisdiction of interest.
In this case, the potential blocking IP would be Gilead’s patent for Remdesivir. Looking at the U.S. claims, Gilead’s ‘958 patent broadly claims the composition. It is not limited by any additional features. As such, the ‘958 patent gives Gilead rights to Remdesivir for all uses. Since Wuhan’s patent application relies on Remdesivir, it’s therapy would fall within the scope of the ‘958 patent.
Moreover, Wuhan’s therapy would likely also run afoul of Gilead’s ‘016 patent application which is directed to the method of treating coronaviridae infection with Remdesivir. Since COVID-19 is a specific coronavirus, any methods of “treating COVID-19” would likely fall within the scope of “treating coronaviridae infection.” Just as with the ‘958 patent, Wuhan’s application of using Remdesivir to treat COVID-19 infections would encounter obstacles with the ‘016 patent application.
As you can see, the questions of how Wuhan can patent a treatment for COVID-19 using Gilead’s pre-existing technology involves understanding the differences between being able to patent an invention and being able to actually commercialize it. Of course, finding that certain patent rights exist that could block commercialization of Remdisivir for the treatment of COVID-19 does not necessarily end the analysis. Designing around Gilead’s patents, licensing Gilead’s patents, or even obtaining a compulsory license in this situation can help Wuhan overcome the patent hurdles to commercialization.
Patent landscape studies are really powerful tools. They can provide a lot of valuable information to a company about competitor’s strategies, currently existing and unexploited market opportunities, and technology trends, and can even increase the valuation of a company and its patent portfolio. We discussed some of this information in a previous post.
But did you know that investors also place a large value on landscape studies? Below are five reasons why investors like to see landscape studies when evaluating a company.
1. Landscape studies provide an overall picture of a company’s market position in the context of its own field and provide a glimpse into potential pathways for future growth. Such studies have powerful mapping capabilities that will not only show you where your company currently stands in the market, but will also identify white space that can offer additional opportunities for growth and development. Taking advantage of this information can help a company plan its current and further research projects.
2. Landscape studies can identify hurdles to commercialization. One such hurdle can come from market over-saturation. If a company is developing IP and products in a crowded space, that company may not only face a lot of competition when it enters the market, but may also face potential infringement claims. Another hurdle can be from technology limitations. If a company is developing IP in a space that has no active competition, there may either not be demand for the product or there may be serious technical problems with the underlying technology. Identifying such issues is important when evaluating a company’s potential market strength.
3. Landscape studies provide important information about potential competitors. Not all competitors are equal. A landscape study will not only identify competitors in a company’s space, but it can also uncover the relevant strengths of those competitors. Some competitors may have already launched products while others may have only just filed patent applications. Knowing this information can help a company analyze the relative threats that those competitors present and can also provide valuable insights should your company choose to negotiate a license or collaboration agreement with those competitors.
4. Landscape studies can also identify trends in the technology. When mapping the marketplace, these studies can reveal how technology has evolved in a specific space. In the CAR T cell therapy space, for instance, there are currently at least four generations of technology that are being pursued. If a company is working on the first-generation version, that company may be missing out on important market advancements and opportunities that are available to those who are pursuing fourth-generation technology.
5. Landscape studies can breathe life into a company’s business strategy. While this seems like a no-brainer, it is amazing to see companies have no plan or reasoning to justify why they are pursuing certain compounds, certain indications, or certain platform technologies. When done correctly, landscape studies can be used to quantitatively evaluate and justify a company’s rationale for devoting resources to the pursuit of certain development projects while abandoning others.
Overall, landscape studies can be incredibly valuable tools that support and guide a company’s business strategy. Having one on hand, and keeping it updated, when pitching to investors can improve your chances of being seen, respected, and appreciated.

We are often asked by inventors if their ideas and creations belong to their employers. We see this particularly with researchers who develop something at home, in the evening, or on weekends. With most people working from home due to the ongoing coronavirus pandemic, many people have some free time and think that now the right time develop a new app or even write a book.
With creating new inventions, however, there is a risk that your employer could claim ownership over your intellectual property. This is because your employer generally owns the IP rights you created during the scope of your employment.
However, you can retain your IP rights as long as your IP is developed outside the scope of your employment.
Scope of employmentSo what does “scope of employment” mean and what falls under the “scope of your employment?” Scope of employment really comes down to your employment agreement and refers to the work and duties you were hired to perform. If you were hired by a biotech company to research and develop new gene therapies, then any gene therapies you develop would probably fall under the scope of your employment. However, if you develop a language learning program, that program would likely fall outside the scope of your employment.
More challenging situations arise when the IP you develop is similar to that which you were hired to develop. In these situations, your employment agreement will be instrumental in outlining exactly what duties you were hired to perform. However, even the employment agreement can sometimes be unclear when it comes to outlining your duties.
To minimize the likelihood that your employer can claim rights to your invention, the following four tips can help demonstrate that your IP was developed outside the scope of your employment.
1. Start recording everything - Maintaining meticulous records helps reduce questions surrounding ownership over the new IP and can help prove your ownership. Write down your project dates, including the start date, in a diary and keep track of its development stages, including any discussions with third parties that you have had. You can also maintain an electronic record by sending an email to your personal address that documents your contributions.
2. Use your time wisely - Make sure you work on your project outside of your work hours. This means focusing on your project only in the evenings and weekends if your work hours are from nine to five. If you work on your project during work hours, you can risk the employer claiming rights to it.
3. Use separate devices – Similar to the point above, make sure you work on your project using your own devices. Do not use your employer’s computers, tools, copiers, scanners, or other devices for your personal work. Use only your own personal computer or laptop. This means that any inspiration you get while working should be written on paper and pen, and not on your office device. Likewise, use only your personal email when communicating about your invention.
4. Use your own money – Finally, make sure you fund your project using your own resources. This means using your own money to pay for expenses like electricity, paper, permits, and raw materials. Do not claim money from your company for any IP-related expenses. If you use your employer’s money to pay for any parts of your invention, you risk jeopardizing ownership of it.
At the end of the day, whether your employer can claim rights to your invention will come down to whether or not the invention was created within the “scope of your employment.” By using your own resources, time, and money, and keeping a detailed journal of your developments, you can increase the likelihood that your invention will stay in your hands.
On Monday, April 27, 2020, the USPTO published a decision that claims that a machine cannot be an inventor for the purposes of obtaining patent protection. Rather, an inventor must be human or “natural person.”
This decision reminded me of a discussion I had earlier this year when I participated on a conference panel in Dubai to explore patent issues in the new and exciting field of AI. My focus specifically was AI as it applies to biotechnologies, pharmaceutical technologies, and medical devices. While the prospect for developing AI-based technologies seems promising, obtaining valuable patent protection on such technologies can be challenging.
Here I will examine some of the challenges presented in patenting AI in the life sciences field as well as discuss five strategies that may improve the chances for patenting these new technologies.
AI can have many applications ranging from voice-powered personal assistants like Siri and Alexa to trying to identify ones of the most infamous serial kills of all time, the Zodiac Killer. Within the life sciences field, AI has so far been used to detect cancer in radiology, improve accuracy of CRISPR technology by predicting and preventing CRISPR from accidentally editing genomic regions similar to target region, generate and validate new drug compounds, and even to calculate the impact of various treatments on brain tumors by analyzing MRIs.
Because of its unique nature, AI-based technologies in life sciences face problems from both the AI side as well as the life sciences side. From the AI side, Section 101 patent eligibility issues, namely Alice, and Section 112 written description present major hurdles. In addition, there are questions stemming from DDR and Enfish about patenting software. From the life sciences side, Section 101 patent eligibility, namely from Myriad, Section 112 written description, and issues related to inherently, obviousness, and double patenting all present hurdles. Navigating these hurdles individually can be challenging by itself but navigating multiple at the same time can be even more so.
Moreover, the past several years have see uncertainties in court decisions and USPTO guidances and thus the eligibility criteria for AI-based technologies is unclear. This uncertainty stems from the Mayo and Alice cases.
So what do you do when you try to patent a technology with so many uncertainties? Below are five strategies that can help
First, narrow the claims to a specific product. This is not the time to try to carve as much white space for yourself as possible. Focus on the product and make sure the claims cover that product. As the law develops around AI, broadening the scope of such claims will likely be possible but until then, patent eligibility and written description are hurdles that, more often than not, will demand a more tailored approach to claim drafting.
Second, while you want to narrow your claim to cover your particular product, do not just rely on one claim to do so. Instead, draft multiple claims with different claim scopes. This will give you the best chance of not only getting a claim allowed, but also potentially allowing some claims to withstand a post-grant challenge should one arise. In my book, Billion Dollar Patents, I discuss the importance of having varying claim scopes as a way to increase the likelihood that some variations could withstand challenges even when others may not.
Third, draft the specification to include as much detail as possible about the invention, specifically about its novel and nonobvious features. During prosecution of the application, you may need to rely on these features to amend the claims and include limitations. Since these types of inventions, by their nature, present written description challenges, the more information you provide about its features, the better the chances to overcome Section 112 hurdles.
Fourth, draft the specification to show how the invention provides a solution to a problem. This is a follow up to the previous point about providing as much detail as possible about the invention. If you can show that the invention solves a problem, the invention becomes more concrete because it has a purpose. In addition, the 2018 European patent eligibility guidelines require that the applicant “establish a causal link to the technical purpose,” so following the guidelines from a country that is more evolved in its eligibility guidelines can be helpful.
Finally, choose the jurisdictions in which you want to patent in carefully. You may want to first protect in countries where the laws are more clear, such as in Europe, and then enter other countries, including the U.S., when the rules are still being developed. Moreover, you can avoid countries where it does not seem that AI will be allowed at all and focus time and effort on those which could allow it.
Overall, AI presents a lot of exciting opportunities in the field of life sciences and patenting technologies in this space presents some unique challenges. Until the rules surrounding patent eligibility become more clear, drafting AI-based applications with a focus on providing as much detail about the invention as possible, narrowing the claims to the invention, and looking for guidance from more established AI jurisdictions can improve the likelihood of of obtaining patent protection at home.
