U.S. Patent and Trademark Office (USPTO) Director John Squires has initiated a review of a recent Patent Trial and Appeal Board (PTAB) decision concerning a tire sensor patent held by Cerebrum Sensor Technologies Inc. This move underscores Squires’ commitment to enhancing the integrity and fairness of the patent adjudication process.
Since his confirmation in September 2025, Squires has actively engaged in overseeing PTAB decisions. Notably, he vacated a PTAB ruling on U.S. Patent No. 11,488,451 due to inconsistencies in expert testimony, emphasizing the necessity for credible evidence in inter partes review proceedings.

In a significant policy shift, Squires announced on October 17, 2025, that he would personally decide whether the PTAB will hear patent validity challenges. This authority had been delegated to PTAB judges since the board’s inception in 2012. Squires cited the need to address concerns around the board’s structure and perceived conflicts of interest, especially the view that judges may be incentivized to accept petitions to increase their own workloads and associated resources.

These actions reflect Squires’ broader strategy to ensure that patents are “born strong,” addressing concerns about the quality of patents issued by the USPTO. During his confirmation hearing, he highlighted that inter partes reviews at the PTAB reveal a 68% error rate, indicating that nearly seven in ten patents issued are later found defective.

By assuming direct oversight of PTAB decisions and emphasizing the importance of credible expert testimony, Squires aims to bolster public trust in the patent system and ensure that patent rights are adjudicated fairly and transparently.
