About Sughrue Mion PLLC

From our inception in 1957 to the present we have focused solely on IP. We cover every aspect of patent and trademark law. We have obtained more U.S. patents than any other law firm in the world. We are always one of the top two firms in the annual rankings by number of issued patents. We provide counseling and opinions on the full range of patent issues in every technology from biosimilars to nanotechnology. Sughrue has been a leader in interference law for over 40 years and has earned an international reputation in this arcane field. We are expert in ex parte and inter partes reexamination proceedings. And we are already steeped in Post Grant Review under the America Invents Act, proceedings for which we are uniquely qualified due to our deep prosecution and inter partes experience before the PTO.

Summer associate program

As an integral part of our recruiting process, each year we invite a number of second year law students to spend the summer working with us. We look for motivated individuals with a strong academic background, preferably in technology or science, preparing for a career in intellectual property law. During their time with us, summer associates are given the opportunity to experience several different areas of Sughrue's practice. Individuals with expertise in a particular field of science or technology are encouraged to participate in projects that will allow them to use their special skills and knowledge. Our Summer Associate Program is designed to provide training in the substantive and procedural aspects of the practice. To this end, each summer associate is assigned two mentors, one partner and one associate, who are responsible for ensuring the quality and variety of work, as well as timely and appropriate feedback.

Summer associates also have plenty of opportunities to socialize, enjoy new experiences and get to know us. At the end of the summer, we hope that program participants will have gained new insight into the practice of intellectual property law and have a little fun along the way.
