PTAB Decision Highlights Ongoing Scrutiny of Tech Patent Validity Amid TikTok Challenge

The Patent Trial and Appeal Board (PTAB) has recently invalidated the majority of claims in a media programming patent challenged by TikTok, while allowing one claim to stand. This decision follows TikTok’s efforts to contest the patent’s validity amid allegations of infringement in federal district court.

In June 2025, the PTAB addressed arguments concerning TikTok’s eligibility to file inter partes review (IPR) petitions, given its ties to the Chinese government. The Board rejected claims that TikTok’s connections to China should bar its participation in IPR proceedings, affirming that TikTok qualifies as a “person” under the relevant statutes.

Recent statistics from the PTAB indicate a trend of invalidating a significant portion of challenged patent claims. For instance, in December 2024, the Board canceled 77.57% of instituted claims across 27 IPR and post-grant review (PGR) final written decisions. Similarly, in January 2025, 80.49% of instituted claims were canceled across 33 final written decisions.

These developments underscore the PTAB’s role in scrutinizing patent validity, particularly in the technology sector. The Board’s decisions can significantly impact ongoing litigation and the strategic approaches of companies involved in patent disputes.
