Why is it important to record business name changes and mergers for patents?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Recording business name changes and mergers is crucial for maintaining an accurate chain of title for patents. MPEP 314 emphasizes this importance:

• For name changes: Although a mere change of name does not constitute a change in legal entity, it is properly a link in the chain of title.
• For mergers: Documents of merger are also proper links in the chain of title.

Recording these changes ensures:

1. The USPTO has up-to-date information on patent ownership
2. Third parties can accurately identify the current patent owner
3. The chain of title remains clear and unbroken, which can be important for future transactions or litigation
4. Compliance with legal requirements for maintaining patent rights
