Oblon was recognized by The Legal 500 as one of the America’s leading firms in Patent Prosecution, Re-Examination and Post Grant Proceedings for the 11th straight year. Each year, Legal 500 analyzes the capabilities and strengths of law firms across the world through extensive research and client feedback. In the 2019 rankings, Legal 500 noted that Oblon is among the most active patent filers in the U.S. Legal 500 said, “The practice’s deep bench allows for wide-ranging sector coverage, with a particularly busy caseload in the chemical, electrical and mechanical, and pharmaceutical and medical device sectors.”

“We are proud to again be ranked among the best IP firms in the United States Legal 500,” said Managing Partner Philippe Signore. “Being recognized by Legal 500 is an honor and a testament to our team’s dedication, and the passion we feel and the skills we bring to the practice of intellectual property law on behalf of our clients.”
