On July 15, 2019, the USPTO's Patent Trial and Appeal Board (PTAB) published a second update to the AIA Trial Practice Guide (TPG) ("2nd Update"), providing additional guidance for trial practice before the Board.

The original TPG was published in August 2012, concurrent with the promulgation of the AIA Trial Rules. In August 2018, the USPTO published the first update to the TPG.

The USPTO has now issued a second update for certain sections of the TPG to provide further guidance to the public. This TPG update is not all-encompassing, and there may be further revisions as the USPTO continues to review AIA trial proceedings.

Among other topics, the updated sections of the TPG include guidance on:

The Trademark Scam Field Guide: Look-Alike Filing Sites, Fake USPTO Notices, And How To Get Out If You’ve Been Caught

A business decides to file a trademark. Someone on the team searches for a familiar online legal-services brand, clicks the first result, and lands on a site with a similar-sounding name, a polished design, five-star reviews, and a low flat fee. The application gets filed. Months later the business learns the “service” was not who they thought it was, the filing was signed by someone with no authority to sign it, and the USPTO has suspended the application along with hundreds or thousands of others from the same shop.
