Companies across the world depend on Oblon to help them to establish, leverage and protect their IP assets in the United States and abroad. Headquartered within steps of the US Patent and Trademark Office (USPTO), with an affiliate office in Tokyo, Japan, Oblon is one of the largest law firms in the United States focusing exclusively on IP law.

For nearly 50 years, Oblon has provided a full range of IP services to companies based in Japan, France, Germany, Italy, the United States and other areas of the world. Many of the firm’s culturally aware attorneys speak several languages, including Japanese, French, German, Mandarin and Korean, to enable more efficient communication with the firm’s global clients. Oblon’s team of over 130 attorneys, registered patent agents and technical advisers include some of the United States’ most respected IP practitioners.

The firm is consistently recognised as an industry leader, with annual accolades from reputable publications such as:

  • US News – Best Lawyers (named a Best Law Firm in 2017);
  • Corporate Counsel Magazine (named a Go-To Law Firm by the top 500 US companies); and
  • Intellectual Property Today (ranked first on the list of Top Patent Firms).

In 2017 the firm was ranked first in the annual Ocean Tomo/IAM rankings for the quality of the patents that it obtains for clients in the categories of industrials and overall. The firm has obtained more US utility patents than any other firm in the world for over 27 consecutive years.

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 US Supreme Court. Oblon also represents Mirowski Family Ventures, LLC in the Medtronic Inc v Boston Scientific Corp Supreme Court case, argued in November 2013. IAM named nine Oblon partners Top Patent Practitioners. Seven Oblon partners were named in the list of The Best Lawyers in America for 2014 and 11 Oblon partners were named IP Stars by Managing Intellectual Property Magazine.

Additionally, the firm’s post-grant practice group continues to dominate the inter partes review proceedings space that has emerged as a result of recent patent reform legislation – namely, the America Invents Act. At present, Oblon leads all other firms in the number of such proceedings that it handles and the number of different clients that it represents.

In 2012 several of the firm’s post-grant partners authored the treatise Post-Grant Proceedings Before the Patent Trial & Appeal Board, which is a comprehensive overview of all aspects of post-grant patent practice and which was published by the Practicing Law Institute (PLI) in 2013. The treatise’s first update, also authored by Oblon partners, is now in the final stages of publication by PLI.

Oblon is headquartered in an expansive building adjacent to the USPTO in Alexandria VA, and operates an affiliate office in Japan to serve its large international client base. The firm’s approximate 500 professionals, including nearly 100 attorneys, provide clients across the world a full range of IP law services.
