Richard (Rick) L. Treanor, Ph.D., a member of the firm’s Management Committee, chairs the Chemical Patent Prosecution group and co-chairs the Patent Prosecution group. His practice includes opinions, counseling, litigation and important prosecution matters. As a former Examiner in the Special Laws Administration Division of the United States Patent and Trademark Office (USPTO), Dr. Treanor provides an insider’s perspective on USPTO policies, processes and procedures, and maintains a solid working relationship with the USPTO staff.

Dr. Treanor possesses a deep understanding of the underlying technologies and sciences involved in his clients’ innovations gleaned from years of specialization in chemical patent prosecution, doctoral studies in organic chemistry, and post-doctoral research in the field of nanostructures.

Having prosecuted thousands of patents, Dr. Treanor is especially skilled at handling complicated, high-stakes proceedings before the USPTO. Working with both foreign and domestic clients, he helps to identify patentable products and design-around competitor patents in order to obtain broad protection for his clients’ innovations.

Dr. Treanor advises his clients on a wide range of issues including risk assessment, information disclosure requirements, licensing arrangements, strategic planning and the intricacies involved in patent reexamination, reissue, application revival, accelerated examination, and group prosecutions. He also works collaboratively with law firms representing clients with intellectual property challenges to help them navigate the USPTO.

Before practicing law, Dr. Treanor earned a National Academy of Sciences/National Research Council Fellowship and conducted post-doctoral study at the Biomolecular Science and Technology Center of the U.S. Naval Research Laboratory.

Oblon is headquartered within steps of the United States Patent and Trademark Office (USPTO), and has an affiliate office in Tokyo, Japan. Oblon is one of the largest law firms in the United States focused exclusively on intellectual property law.

The Firm is consistently recognized as an industry leader, with annual accolades from reputable publications such as Chambers and Partners USA, U.S. News & Best Lawyers (named “a Best Law Firm” for 2018), Corporate Counsel Magazine (named a “Go-to” law firm by the top 500 U.S. companies), and Intellectual Property Today (ranked #1 on the list of “Top Patent Firms”). The Firm has obtained more U.S. utility patents than any other firm in the world for over 27 consecutive years.

Oblon’s attorneys and professionals collectively offer decades of USPTO insight and expertise and serve as an invaluable resource to Oblon clients that have come to rely on the firm’s uniquely qualified experts, including former Commissioner for Patents, Margaret A. (Peggy) Focarino, former Assistant Secretary of Commerce and Commissioner of Patents and Trademarks, the Honorable Gerald J. Mossinghoff and the former Deputy Commissioner for Patent Examination Policy, Stephen G. Kunin, as well as many other former patent examiners and administrative patent judges (APJs).

In addition to its renowned patent prosecution practice, the firm has a precedent-setting litigation practice, having litigated cases such as the Festo case before the U.S. Supreme Court. The Oblon litigation team has extensive knowledge and experience in all aspects of complex intellectual property litigation involving patent, industrial design and trade secret disputes.

Additionally, the firm’s post-grant practitioners are some of the most experienced in the country. The Group routinely recovers patent portfolios made subject to post-grant disputes as a result of high-profile, concurrent litigation valued at hundreds of millions of dollars.
