Haynes and Boone, LLP scored the highest win rate among the 10 law firms with the heaviest caseloads representing petitioners before the Patent Trial and Appeal Board (PTAB) in 2022, Intellectual Asset Media (IAM) reports.

In a Feb. 6, 2023 article, IAM credited Haynes Boone with a 45.9% success rate for PTAB petitioners, the best winning percentage among the select law firms with heavy caseloads.

In 2022, Haynes Boone ranked as the third busiest firm representing PTAB petitioners, with 67 cases filed on behalf of patent challengers in 2022.

IAM said it used Docket Navigator to review PTAB filings, noting that it counted only “full victories” in its ranking of firms’ win rates.

“We are thrilled to earn this recognition, but our greatest satisfaction comes from having helped so many clients achieve favorable outcomes,” said David O’Dell, partner and chair of the firm’s Patent Trials and Counseling Practice Group. “We look forward to continued success in 2023.”
