§253 Disclaimer

Title 35 › Part III— PATENTS AND PROTECTION OF PATENT RIGHTS › Chapter 25— AMENDMENT AND CORRECTION OF PATENTS › § 253

Last updated Apr 5, 2026|Official source

Summary

Patent owners can give up any whole claim in a patent, or give up the whole remaining time of a patent or just the ending part of its term, by filing a written disclaimer, paying the required fee, and recording it with the Patent and Trademark Office. If one claim is found invalid, the other claims stay valid. A part‑owner may only give up rights for the share they own, and the recorded disclaimer counts as part of the patent for them and anyone who gets their rights.

Patents — Source: USLM XML via OLRC

(a)Whenever a claim of a patent is invalid the remaining claims shall not thereby be rendered invalid. A patentee, whether of the whole or any sectional interest therein, may, on payment of the fee required by law, make disclaimer of any complete claim, stating therein the extent of his interest in such patent. Such disclaimer shall be in writing, and recorded in the Patent and Trademark Office; and it shall thereafter be considered as part of the original patent to the extent of the interest possessed by the disclaimant and by those claiming under him.
(b)In the manner set forth in subsection (a), any patentee or applicant may disclaim or dedicate to the public the entire term, or any terminal part of the term, of the patent granted or to be granted.
