He has appeared in over 90 litigations and lead counsel in over 50 IPR's.

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. Thomas was 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 (7th – 20th eds.) (now called PLC Which Lawyer? Yearbook)) for the years 2002 – 2015. Thomas was also named as a prominent practitioner by the Practical Law Company in PLC’s Cross-Border IP in Business Transactions Handbook for 2008-2015. Thomas was also named as a “Leading Lawyer” (2004 - 2015, 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 maintenance 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.
