Thomas J. Wimbiscus


Thomas J. Wimbiscus, a shareholder with McAndrews, Held & Malloy, has more than thirty years of experience and practices in all areas of intellectual property litigation, as well as the acquisition and management of patent, trademark, copyright, and trade secret protection. He has appeared in over 100 litigations and over 90 IPR's. He was named one of the 20 most active IPR practitioners in the U.S. for patent owners. (Docket Navigator 2014.)

Thomas was designated a fellow of the Litigation Counsel of America (LCA). The LCA is a trial lawyer honorary society composed of less than one-half of one percent of American attorneys – based on effectiveness and accomplishments, in both litigation and trial work. He was named one of the Top 500 Leading Lawyers Across the Globe by Intercontinental Finance & Law in 2016 and one of the Top 100 Lawyers for 2016/17 by LegalComprehensive.com.  Thomas was also named as “recommended” intellectual property (patent) counsel by an independent, global survey conducted by Practical Law Company (PLC Global Counsel 3000, Choose Your Counsel Wisely). Thomas was also named as a prominent practitioner by the Practical Law Company in PLC’s Cross-Border IP in Business Transactions Handbook. Thomas was also named as a “Leading Lawyer” (2004 - 2017, awarded to fewer than five percent of licensed Illinois lawyers) by independent survey.

His litigation successes include numerous multi-million dollar awards and settlements, as well as patent infringement victories before the U.S. International Trade Commission. His experience also encompasses the acquisition and procurement of patents, trademarks, and copyrights.

Thomas has served as co-trial counsel in a four-week jury trial resulting in a patent infringement award of over $80 million with a finding of willful infringement (reversed in part and remanded). He has worked in such diverse technologies as prodrug and other pharmaceutical technologies; semiconductors for cellular telephones, Wi-Fi and GPS technologies; oil refining; polyurethane, surfactant, and other technologies in the chemical arts; alternative fuels (including biodiesel); biotechnologies; and medical devices including implantable cardiac defibrillators, pacemakers, and balloon angioplasty catheters.
