The Firm is consistently recognized as an industry leader, with annual accolades from reputable publications such as U.S. News & Best Lawyers (named “a Best Law Firm” for 2015), 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”).

Firm History

1968

Norman Oblon launched what was to become Oblon, Spivak, McClelland, Maier & Neustadt, LLP, one of the nation’s leading full-service intellectual property law firms. He was just 26 years old. Mr. Oblon met his future partners, Marvin Spivak, Irvin McClelland and Gregory Maier at the U.S. Naval Laboratory, where they were all working as civilian patent advisors for the U.S. Navy.

1973

Together the founders quickly landed a string of impressive clients in the U.S. and in Japan- a still-undiscovered market. The founders also co-authored a book designed to guide Japanese companies through the U.S. patent prosecution system. It was one of the first books of its kind to be published in Japanese. Nearly 40 years later, the firm boasts a significant Japanese client base and has been ranked first in the number of patents obtained for each of the last 25 years.

1974

As the firm’s patent prosecution work took off, Art Neustadt joined the firm to lead the litigation practice. The firm continued to expand its focus to include the areas of ITC litigation, patent interferences, patent reexamination/reissue, copyright, trademark, industrial designs, opinions and counseling.

1980

Oblon created a robust client training program that it uses to this day to train overseas clients in U.S. patent law. This program continues to provide firm clients with an in-depth understanding of relevant issues as well as the various options available when important decisions need to be made.

1993

As the firm grew, it developed a recruiting method that was mostly unheard of at the time. Instead of only hiring attorneys fresh from law school, it groomed talented academics for a successful law career by identifying promising Ph.D.s and paying their law school tuitions. Thus Oblon became one of the first firms to develop a cadre of credentialed attorneys who knew the USPTO Patent Examiners and understood science and technology.

2009

The firm announces the opening of a new Oblon office in Tokyo, Japan to better serve the firm's expansive and growing Japanese client base. 

2015

After a recent re-branding effort, the firm is now called Oblon, McClelland, Maier & Neustadt, LLP, and is headquartered in an expansive building located adjacent to the USPTO in Alexandria, Virginia. The firm operates an affiliate office in Japan to serve its large international client base. The firm’s approximately 500 professionals, including 100-plus attorneys, provide clients across the world a full range of intellectual property law services.
