Sughrue Mion PLLC

Sughrue is an Intellectual Property Law Firm. Exclusively.

From our inception in 1957 to the present, we have focused solely on intellectual property law. We handle every aspect of IP law, and we have kept this area as our exclusive focus as a way to ensure that we provide the highest possible expertise to our clients. We have obtained more U.S. patents than any other law firm in the world, and we have successfully litigated IP disputes in every popular forum, including U.S. District Courts across the country, the United States International Trade Commission, (USITC), the Patent Trial and Appeal Board (PTAB), and the Trademark Trial and Appeal Board (TTAB).

With nearly 100 patent attorneys that have science or engineering degrees, many at the post-graduate level, we can provide in-depth coverage of any technology area. The size of our technology teams allows us to help clients efficiently develop large patent portfolios and litigate complex technology disputes. We are steeped in Post Grant Review proceedings under the America Invents Act, including Inter Partes Review (IPR), Post-Grant Review (PGR), Covered Business Method (CBM), reexamination, reissue, and interference proceedings for which we are uniquely qualified due to our deep prosecution and inter partes experience before the PTO.
