Reissue Patent: Key Insights into Its Legal Definition and Process

Definition & Meaning

A reissue patent is a type of patent granted by the U.S. Patent and Trademark Office (PTO) to amend significant errors found in an existing patent. This process allows the original patent holder to correct issues without altering the duration of the patent. Reissue patents can be applicable to utility, design, or plant patents. Only the patent holder is eligible to file for a reissue.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A patent holder realizes that their patent claims are too narrow, limiting the protection of their invention. They file a reissue application to broaden these claims within the two-year window.

Example 2: A patent is issued with an incorrect specification that misrepresents the invention. The patent holder files for a reissue to correct this inaccuracy. (hypothetical example)
