Who is the patent inventor?

An inventor is an individual person (not a company or organization) who contributes to an invention as defined by the patent claims. In a design patent, the claim consists of the drawings so a design patent inventor would be anyone who contributed to a feature shown in the figures.

In a utility patent, however, the claims do not consist of the drawings or the detailed description. Utility patent inventors, therefore, are the ones who contributed to the invention as defined by the wordy claims.

How to correct inventorship

If an inventor was inadvertently omitted from or added to the list of inventors in a non-provisional patent application, inventorship may be corrected by filing a request to correct inventorship that includes an updated Application Data Sheet and a USPTO processing fee under 37 CFR § 1.17(i). [See MPEP 602.01(c), and 37 CFR 1.48].

What is a derivation proceeding?

For patent applications filed on or after March 16, 2013, a derivation proceeding may be available for a true inventor to challenge the inventorship of an issued patent. The alleged true inventor must not be the first to file a patent application (otherwise, the application by the true inventor may already qualify as prior art under 35 USC 102).
