WASHINGTON, March 21, 2013 /PRNewswire/ -- Sterne, Kessler, Goldstein & Fox P.L.L.C. (Sterne Kessler), an intellectual property law firm in Washington, DC, today formally announced its Patent Office Litigation practice. The America Invents Act of 2011 (AIA) ushered in a variety of new ways to challenge or strengthen patents at the U.S. Patent and Trademark Office. Together with the pre-AIA proceedings, Patent Office Litigation now includes: Inter Partes Review, Post Grant Review, Covered Business Method Patent Review, Derivations, Interferences, and Patent Reexamination. Sterne Kessler's Patent Office Litigation practice is designed to help entities navigate this new patent landscape. "As implementation of the AIA has unfolded, our team has invested thousands of hours digesting and analyzing the new laws, the new rules, and the decisions coming out of the Patent Trial and Appeal Board," said Michael B. Ray, managing director of Sterne Kessler. "We are now putting that investment to work on behalf of our clients – they also benefit directly from our prior experience in more than 50 interference proceedings, dozens of foreign oppositions, and more than 400 ex parte and inter partes patent reexaminations." Sterne Kessler has long been a leader in the area of high quality, high value patent preparation and prosecution, and has built a strong litigation practice before the U.S. International Trade Commission and the U.S. District Courts. Post-AIA, Sterne Kessler has placed a great deal of effort in establishing a leadership position in Patent Office Litigation. Currently, Sterne Kessler ranks first in the number of inter partes reviews being handled (27) and first in the number of instituted inter partes review trial proceedings (six). In 2012, Patent Office Litigation (Thomson Reuters Westlaw) was authored by the Sterne Kessler team. Learn more about the firm's Patent Office Litigation practice on the web here.
