Did You Know About Supplemental Examination?

The America Invents Act (AIA) ushered in an era of Patent Office trials to adjudicate the validity of issued patents. The AIA, however, created an additional, lesser used, avenue to address patent validity. This procedure is known as Supplemental Examination under 35 USC 257.

Supplemental examination can only be requested by a patent owner, and no third party participation is permitted. Any type of information can be submitted on any ground of patentability.
