Taft IP attorneys Roshan Shrestha, Ph.D. and Ryan White achieved a significant victory for patent owner Mr. Sachin Jhunjhunwala in a case before the Patent Trial and Appeal Board (PTAB). On Sept. 14, 2021, the PTAB denied a post grant review (PGR) challenge by AAVN, Inc.

The case involved U.S. Patent No. 10,689,782 B2 titled “Textile Fabric Fabricated of Twill Weave Sheeting” and issued on June 23, 2020. The textile fabric is used in bedding including sheets, pillow cases, duvet covers, etc. The petition contended that the granted claims are unpatentable under § 103 for obviousness over the prior art and under § 112 for lack of adequate written description. The Taft team, assisted by Khurana and Khurana, put together a strong preliminary patent owner’s response. After review, PTAB denied the petition explaining that the petition failed to identify the grounds and evidence for the challenge. This denial means that the PGR process was terminated at the outset and the patent owner did not have to go through PTAB review process which could last up to 18 additional months.
