Douglas R. Nemec

Partner, Intellectual Property Litigation
Douglas R. Nemec concentrates his practice on litigating complex cases involving intellectual property and technology. He approaches every case with the philosophy that good advocacy transcends geography, technology space and substantive area of the law.


In the diverse range of matters Mr. Nemec has led in state and federal courts from coast to coast, he has obtained positive results for clients in matters ranging from patent infringement to trade secrets to high-stakes licensing disputes. The technologies involved have been equally wide-ranging. With a background in bioengineering, Mr. Nemec has a particular fondness for life sciences matters, but has equal aptitude helping judges and juries to understand technological matters involving computers, electronics, industrial chemicals and mechanical structures.

Working alongside Skadden’s corporate practice, Mr. Nemec has significant experience beyond litigation, including advising on mergers and acquisitions, licensing, and general IP counseling. As a registered patent attorney, he also represents clients in matters before the U.S. Patent and Trademark Office, which has become an important complement to the firm’s IP litigation practice. Additionally, in life sciences matters, Mr. Nemec has advised on defense of patent infringement claims, enforcement of patent and other IP rights, and inter partes reviews related to the treatment of a variety of ailments and diseases.

Mr. Nemec is part of the Skadden IP Litigation Group that was named a Powerhouse in BTI Litigation Outlook 2018; a leading firm in the trademark field by World Trademark Review in 2018; ranked as a nationwide Tier 1 firm for intellectual property litigation by U.S. News — Best Lawyers Best Law Firms; and named to The National Law Journal’s Intellectual Property Hot List for multiple years. Mr. Nemec also was named to Intellectual Asset Management’s 2019 IAM Patent 1000, Chambers USA 2019 and 2020, The Best Lawyers in America 2020 and as a 2017 BTI Client Service All-Star by BTI Consulting Group. He also has been recognized as a leader in IP by Managing IP and LMG Life Sciences.

  • representing JP Morgan Chase as lead counsel in multiple patent infringement matters, including securing findings of non-infringement and patent invalidity at the trial and appellate court levels in Delaware, California and the Federal Circuit;
  • defending Caterpillar against patent infringement claims asserted by an after-market parts supplier, and pursuing counterclaims including copyright infringement, false advertising and unfair competition in the same matter in Chicago federal court;
