Know Your PTAB Judges: Meet PTAB Judge Jennifer Bisk

In this second installment of Docket Alarm’s Know Your PTAB Judge newsletter, we are proud to feature Judge Jennifer Bisk.


Judge Jennifer Bisk is a graduate of the George Mason University School of Law. Prior to law school, she obtained a Bachelor of Science in engineering, computer science, and electrical engineering from Vanderbilt, and a Master of Science in computer science from Stanford.

Judge Bisk has an extensive history clerking for various courts. She has served as a law clerk for the Hon. George W. Miller at the U.S. Court of Federal Claims and then for the Hon. Richard Linn at the Court of Appeals for the Federal Circuit. During law school, she was a judicial intern for the Hon. Randall R. Rader at the Federal Circuit and also for the Hon. Stephen S. Mitchell at U.S. Bankruptcy Court for the Eastern District of Virginia.

In addition to her clerking experience, Judge Bisk also has patent experience in both transactional matters, at Cooley, Godward and Kronish, and in litigation at Crowell & Moring and at Sterne, Kessler, Goldstein & Fox.

PTAB Record

The Honorable Jennifer Bisk was sworn in to the Patent Trial and Appeal Board on March 1, 2012. During her tenure on the court, she has issued an impressive 35 final written decisions— canceling all instituted claims in 17 petitions, canceling some claims in eight petitions, and refusing to cancel any instituted claims in 13 petitions.

Notable rulings include Judge Bisk’s written decision against instituting a petition for Inter Partes Review (IPR) filed by IBM against known patent aggregator Intellectual Ventures. IPR 2014-00681. The patent at issue involves an intrusion-detecting security system. Judge Bisk’s decision went through IBM’s five alleged grounds of unpatentability (citing 35 U.S.C. §§ 102 and 103), which relied on four different examples of prior art. Ultimately, the court determined that IBM did not show a reasonable likelihood that it would prevail on demonstrating the unpatentability of any of the challenged claims, and refuted all five grounds of IBM’s challenge.
