D. Clay Ryerson

D. Clay Ryerson is a patent litigation attorney with Munck Wilson Mandala, primarily representing defendants in intellectual property disputes. His practice has involved technology areas such as residential proxies, web data extraction, and web script management.

In a notable recent case, Ryerson served as counsel for Oxylabs in Bright Data, Ltd. v. Oxylabs (formerly Luminati), a patent infringement lawsuit. While a federal jury initially found Oxylabs liable for willfully infringing Bright Data's patents in 2021, the defense strategy included challenging the patents' validity before the U.S. Patent Office (USPTO). These USPTO invalidity findings were subsequently upheld by the U.S. Court of Appeals for the Federal Circuit on August 1, 2025, and the U.S. Supreme Court declined to review the decision on February 23, 2026, making the invalidation of key Bright Data patents final. This significant outcome effectively nullified the earlier infringement verdict against Oxylabs.

Based on the strategic use of USPTO proceedings to invalidate asserted patents in a major litigation, Ryerson's work demonstrates an understanding of post-grant review strategies in conjunction with district court defense. Details regarding Ryerson's specific bar admissions or educational background are not readily available in public sources.
