How should you write a patent

Anatomy of a Patent Application

Let’s first understand the basic outline of a patent application. While drafting, the application will primarily include these sections.

  • Title of the application
  • Cross-Reference to related applications
  • Background of the invention
  • Summary of the invention
  • Brief Description of the drawing(s)
  • Elaborate description of the drawings
  • Claims
  • Abstract and Drawing(s)

The draft needs to follow this order. However, it’s advisable to start off with drafting the claims section first as it’s the most important part of the patent. It forms the basis for the rest of the application. Writing the claims will also pave the path for your drawings because you’ll be sure to cover the relevant areas. We’ll further see how to write the important sections of the applications.

Take a look at this patent application from Nike, for an illuminating shoe. Notice how it mentions the title, “Method for Illuminating an article”. It is simple and crisp. The entire application is 39 pages long. It contains elaborate drawings and the description goes on for about 11 pages. This is to ensure that the patent has very broad and comprehensive protection.

Write a patent – How to draft the claims?

We’ve already made the importance of the claims section clear. Let’s understand the drafting of the claims section in detail.


First, you should work on two declarations, one broad and general, and the other one more specific. The first declaration should describe the broad terms of your invention, without any pointless ideas. The second declaration should describe your invention more specifically, considering all the realistic possibilities. This is important because the claims need to be current and must have an applicable scope, some broad and some specific. After doing this, you have a broad and generic model of your invention and a very specific one. Check out Omnibus Claim: Importance of Narrow and Broad Claim Scope and Antecedent Basis.

Characteristics of the Claims (and hacks)

Let’s dive deeper into the important characteristics of the claims. The crucial points to keep in mind while drafting the claims are:

  • The claims should be complete.
  • They should have adequate support in terms of what area they intend to cover.
  • The claims should be precise.

The claims should be written such that each claim must be its own sentence and it should be clear to the reader. You must ensure that you don’t use lengthy technical language by using words like “strong”, “major part”, “such as”, etc. This can prove to be the differentiating factor in your application. Each claim identifies the innovative features of the invention and the elements that put the claim in context. Make sure to support the claim in the description section by explaining your invention elaborately.

Claim Structure

The structure of every claim should be as follows:

  • Introductory phrase – This phrase introduces the invention and often the purpose of the invention.
  • The body – This is the legal description which entails the exact ideas that you are seeking protection for.
  • Interlink between the two – This section links the body and introductory phrases. It’s important for how restrictive or permissive a patent is.

In conclusion, the claims section is the heart of your application. Everything else, from drawings to description, should revolve around the claims. The claims define the legal boundaries of your patent so they need the utmost care and attention during drafting.

Tips and Tricks to Write a Patent

You need to make your application stand out, so you require a few hacks which will help you achieve it. Let’s read about them now:

  • Description of Embodiments: Inventors often get confused between “different embodiments of the invention” and “different embodiments”. You must understand that your invention has more than just one model. If you don’t describe something, then it isn’t a part of your invention.

 For example, consider that you say that your invention comprises of the components A+B+C+D. If someone else presents an almost identical invention but leaves out certain components, then it wouldn’t be an infringement. That’s because your claim meant that the invention is complete when it has all 4 components A, B, C, and D together. Your description is too narrow. So you must understand the embodiments of your invention and make sure that it is not subject to exposure.

  • Usage of the invention: You should describe alternate models of your invention. These need not be specific, but you should still describe it. Inventors should consider the different ways in which their invention can be put to use. This is to ensure that your protection is all-encompassing and comprehensive.
  • Terminology: You must make sure that the terminology you use is the best fit. It shouldn’t be incorrect or ambiguous at any point because that can lead to exposure. It’s best to hire a professional to draft your application. But, if that is too expensive then you should seek advice on the quality of your draft from a professional.
  • Enablement Requirement and Drawings: When you write a patent application, you must describe all of your inventions that would clarify how to make and use it. You must explain how all the parts of your invention work and interrelate to each other. Further, you must use the drawings wisely. The drawings give a clearer understanding of your descriptions because they provide visuals. An examiner may be able to get an idea about your invention by looking at the descriptions. But when he/she sees the drawings, there will be no doubt left at all.
