Writing patent claims carefully defines the scope of protection for an invention. It is the legally operative part of a patent application. Claims form an essential component of the patent specification and clearly define the patent boundaries. It articulates the entire scope of what you claim as your invention and outlines the exclusive right granted to the claimant.
You can write a claim in either independent or dependent form. An independent claim is a standalone claim. It consists of all the limitations necessary to define an invention. All patent applications contain either one or more “independent” claims embodying the essential features of the invention. Dependent claims are claims that take precedence from an earlier claim. Thus, if possible, it should provide a reference to the earlier claims at the beginning.
There is no one-size-fits-all method while writing patent claims. Based on the nature of the invention involved, the patent claim takes shape. Moreover, the protection sought for the invention characterizes the drafting of the patent claim. Therefore, the application needs to pay meticulous attention to details while writing the claim to protect it from any infringement issues. Each independent claim consists of the preamble, a transitional word or phrase, and the body. Here are few best practices you need to consider while writing patent claims.
Writing Patent Claims: Best Practices
Include both Narrow and Broad Claims
While drafting your patent, you need to include claims and claim sets of varying scope. It would help if you gave the client a wide option range. The inclusion of different scope ranges enables you to access the legal title for several aspects of your invention. Broad claims will involve a wider group of infringers, while narrow will be “valid” in light of prior art not known during prosecution. A practical patent application is likely to begin with broad claims and develops towards narrower claims in scope.
You need to write the claim in clear, concise, and decipherable terms without any trace of ambiguity. It must clearly define the invention for which you seek the protection. Be cautious and choose words that can effectively capture the invention and its variants. It would be best if you watched out for relative terms “thin,” “strong,” “a major part,” “such as,” and more which makes the reader develop a subjective judgment. You should use the right set of words that enables an objective observation.
Complete and Well-Rounded
It would help if you avoided unnecessary limitations in your claims. Support the characteristics of your invention in the claim with appropriate descriptions. Ensure that every claim has adequate support in the specification. The report must support the claim language. The claim should be complete to provide sufficient coverage for the inventive feature and put the invention in the proper context. It must overcome the prior art and ensure that you are not filing invalid claims. Also, each claim should be written in a single sentence and comprise each of the essential defining elements in the correct format.
Thus, claims represent the core of the patent application. It should elaborate on the specific inventive features of your invention. An effective claim will enable others to understand when they are infringing on your rights.
