On June 21, 2017, In Storer v. Clark, the Federal Circuit affirmed a Patent Trial and Appeal Board’s interference decision, which awarded priority to Clark’s pending application (filed May 30, 2003) over Storer’s issued patent. The Court found that Storer’s earlier provisional application (filed June 28, 2002) did not enable the subject matter of Storer’s interfering claims… To satisfy the enablement requirement, applicants should provide either explicit examples of claimed compounds or direction or guidance on how to synthesize the claimed compounds. Disclosing generic structures or general approaches to synthesis does not by itself satisfy the enablement requirement for specific compounds. A known precursor does not enable synthesis of a claimed compound if the application does not disclose the precursor or how to convert it into to a claimed compound.

The crux of this so-called adequate description requirement is that once the first four patentability requirements are satisfied the applicant still must describe the invention with enough particularity such that those skilled in the art will be able to make, use and understand the invention that was made by the inventor. For the most part this requirement can be explained as consisting of three major parts. First is the enablement requirement, next is the best mode requirement and finally is the written description requirement.

One big mistake inventors make is they will go on page after page in their draft patent application about how they came up with the idea for the invention, what the market for the invention is and how they plan on tapping into that market. None of that is appropriate for a patent application. Various pieces, perhaps even all of it, would be appropriate for a business plan. So the first thing inventors need to understand and really internally appreciate is that a patent is NOT a business plan. If you are going to attempt to raise money to pursue your business objectives you will undoubtedly need a business plan and attaching a well drafted and previously filed patent application as an appendix can be useful at times, but a business plan and a patent application play very different roles.

The best mode requirement still exists, although the America Invents Act (AIA) has largely removed any consequences for failing to disclose the inventor’s best mode, which means the current state of the law is at best a bit murky. But why would you ever want to file a patent application that does not disclose something that you prefer or regard as better? The goal of filing a patent application has to be to completely disclose your invention with as much detail and description as possible, paying particular attention to alternatives and variations. So while you may be able to get away with not disclosing any preferences doing so would likely be a tragic mistake.

This so-called adequate description requirement pertains to the level of description that must be included in the ”specification,” which is most typically defined as that part of the patent application that is not a drawing figure and is not a claim. This is the most common definition for the term “specification” because if and when you need to amend an application there are three separate sections for an amendment, one for amendments to the specification, another for amendments to the claims, and a third for amendments to the drawings. When you get to the point of the process where you will need to amend the application (which goes beyond the scope of this article) you will amend anything that is not a claim and not a drawing under amendments to the specification.

It is absolutely critical to understand that this complete and full description MUST be present as of the filing date of your application. If you file an application that does not describe the invention to the required level required by U.S. patent laws the application is defective and it cannot be fixed. The only way to fix an inadequate disclosure is to file a new application with an adequate disclosure, but that means you obtain no benefit from the filing of the earlier inadequate patent application.

Drafters need to think both outside and inside the claims. Outside thinking aims to make the court’s task easier by providing claim terms amenable to straightforward, simple claim construction. Preferably, at least, the key terms are expressly defined, or at least explained through demonstration. Inside thinking takes up the question whether the claim construction supports the patentee’s or owner’s intention, as manifested in the claims and specification. By the time a drafter is “experienced,” she has been exposed to considerable instruction on claim drafting. Claim construction rules, claim drafting principles, claim drafting strategy—the endless seminar. Yet, the Federal Circuit regularly lectures the patent bar on its drafting practices. The difficulty is that among all of our construction rules and strategic principles, we have lost sight of clarity and precision. We need to refocus on basic principles. Indeed, we’re going to need a bigger boat.

Many times inventors fail to adequately describe their inventions because the invention is obvious to them, and they think it will be equally obvious to others. The law, however, requires that a patent application explain the invention to someone who is not already familiar with the invention. One of the best way to do this is to explain it like a child explains things when doing a show and tell at school. Children explain everything in excruciating detail, no matter how obvious. Kids do this when they describe things because they have no idea what the person listening knows, and to them it is new and interesting so they explain everything with tremendous detail (whether you want to hear it or not). That is exactly what you need to do in the application. Explain your invention with so much detail that you will bore the knowledgeable reader to death.

In reality, it is probably better to think of the description requirement as the core to patentability. If you can describe your idea with enough specificity you no longer have an idea, but rather have migrated past the idea-invention boundary, which means you have something that can be patented if it is unique. The crux of this so-called adequate description requirement is that once the first four patentability requirements are satisfied the applicant still must describe the invention with enough particularity such that those skilled in the relevant technology will be able to make, use and understand the invention that was made by the inventor. For the most part, and from a legal perspective, this requirement can be explained as consisting of three major parts. First is the enablement requirement, next is the best mode requirement and finally is the written description requirement.

One of the challenges that a drafter faces when trying to satisfy the enablement requirement is with respect to describing things that can and will vary depending on the circumstances. What you want to do is follow up by explaining the various permutations to help the reader more readily understand what facts, choices or circumstances will have impact.
