With 200 IP attorneys and more than 150 attorneys who focus on patent matters, the strength of Winston & Strawn’s patent practice is clear. Our team continues to receive national recognition for our success in this area of law. In 2016, our IP litigation practice was ranked in the first tier nationally for the fifth year in a row by US News & World Report in its Best Law Firms survey, and Chambers USA selected our IP and International Trade Commission (ITC) practices for national rankings. Additionally, The National Law Journal selected Winston’s Chicago office as the 2016 Chicago IP Litigation Department of the Year (as it had previously in 2013), Texas Lawyer named our Houston team as its 2016 IP Litigation Department of the Year and Law360 named Winston’s litigation department one of the 2016 Top 50 Litigation Powerhouses in the United States. Further, our team is regularly ranked among the top groups by Legal 500 based on our “strong reputation” and “trial expertise,” stating: “Winston’s excellent trial record has helped to feed it a diet of high-stakes patent cases relating to pharmaceuticals, telecoms, and electronics.”

The success of our patent litigation practice has been driven by a simple strategy: we attract the best trial lawyers, support them with strong technical lawyers and those teams get results.

US district court litigation

Winston patent litigators regularly appear in all of the leading patent jurisdictions. For example, between 2012 and 2016 we handled 534 cases in 42 jurisdictions, including:

  • 121 cases in the Eastern District of Texas;
  • 147 cases in the District of Delaware;
  • 56 cases in the District of New Jersey;
  • 44 cases in the California courts; and
  • nearly 200 cases in other key jurisdictions, including the Northern District of Illinois, Eastern District of Virginia, Southern District of New York and Eastern District of Michigan.

ITC litigation

Winston has collectively more than 80 years of experience litigating high-stakes patent infringement cases before the ITC. The firm’s experienced team comprises a number of attorneys who have first-chaired successful ITC trials, as well as a former ITC senior investigative attorney, a former ITC attorney adviser to the chief administrative law judge, a former US Court of Customs and Patent Appeals law clerk and a former US patent examiner. Our attorneys have the education and industry experience to immediately understand complex technology, a working knowledge of the specialised procedural law and the substantive experience to formulate and execute the strategies necessary to succeed at the ITC.

PTAB trials

Winston is ideally positioned for litigation before the Patent Trial and Appeal Board (PTAB) in proceedings such as inter partes reviews, covered business method patent reviews and post-grant reviews. While practice before the PTAB is relatively new, Winston already has significant experience litigating these proceedings successfully. Winston attorneys have appeared in more than 80 PTAB matters and tried several of the first cases to reach hearing.

Patent prosecution

Winston has an active patent prosecution practice that assists clients with the prosecution, development, maintenance and licensing of patent portfolios worldwide. Our patent prosecution attorneys typically file 100-150 US patent applications and obtain approximately 75-100 US patents annually. The firm’s scientifically trained attorneys and patent agents are experienced in the preparation and worldwide prosecution of patent applications pertaining to the traditional sciences, as well as in new and developing technologies. All of our patent attorneys have technical degrees in fields such as electrical engineering, computer science, physics, chemical engineering, chemistry, materials engineering and metallurgy.

Additional statistics about our patent practice include that:

  • nearly 70 of our attorneys have technical degrees, and more than 30 are members of the Patent Bar;
  • more than 30 of our partners have first-chaired IP trials in various courts throughout the United States;
  • over the past five years, our attorneys have handled more than 600 patent cases and more than 100 Federal Circuit appeals; and
  • our ITC group has collectively appeared in more than 75 Section 337 ITC investigations.
