Rule Statements

The construction of a patent claim is a matter of law.

The specification is the single best guide to the meaning of a disputed term.

Scenario: You and a colleague developed a new software feature together, but your employer later tries to patent it listing only your colleague as the inventor. You believe you contributed significantly and should be named.

Your Rights: You have the right to be named as an inventor on a patent if you contributed to the conception of the invention. If you believe inventorship has been incorrectly determined, you may have grounds to challenge it.

What To Do: Gather all documentation and evidence of your contributions to the invention (emails, lab notes, design documents). Consult with a patent attorney to understand your options for correcting inventorship, which may involve legal action.

Is it legal to remove someone from a patent if they were wrongly listed as an inventor?

Yes, it is legal to remove someone from a patent if they were wrongly listed as an inventor, provided there is clear and convincing evidence that they did not contribute to the conception of the invention. This process is called correcting inventorship.

This applies under U.S. patent law.

For Patent holders and applicants

This ruling reinforces the importance of accurately identifying all inventors at the time of patent application. It signals that courts will uphold corrections to inventorship if sufficient evidence demonstrates an error, potentially leading to disputes over patent ownership and validity.

For Inventors and co-inventors
