The head of the U.S. Patent and Trademark Office has recently invalidated decisions from the Patent Trial and Trademark Board (PTAB), in relation to Assa Abloy’s ability to demonstrate the unpatentability of two biometric patents. The office head’s decision was based on the PTAB deploying a definition of a crucial term that neither Assa Abloy nor the patent owner had initially proposed.
Reflecting on the conduct of the PTAB, and the terminology employed throughout the trial period, it became evident that the establishment had used a unilaterally decided definition during the patent validity evaluations. Questioning the fairness and validity of such an approach, the decision was made to discard the previous rulings, which had decreed Assa Abloy’s failure to prove the unpatentability of the patents in question.
This decision by the head of the U.S. Patent and Trademark Office underlines the critical importance of conceptual clarity and terminological precision in legal proceedings, specifically within patent law. The invalidated rulings indicate that the PTAB’s use of a definition that was not consensually agreed upon by both Assa Abloy and the patent owner was considered problematic.
