Eric’s practice includes representing clients in various technology and commercial disputes throughout the U.S.  He focuses primarily on intellectual property litigation and works with his clients to achieve goal-oriented litigation.   Eric has taken ten cases to verdict, in matters ranging from life-saving medical devices to farming technology.

Prior to entering private practice, Eric served as law clerk to the Honorable Peder B. Hong in Minnesota’s First Judicial District. 

Client Recommendations:

​Eric represented H&S Manufacturing in a contentious, patent infringement matter, which was a bet-the-company case.  Its Chairman and CEO, Chris Heikenen, noted, “I knew Eric was crackerjack smart and quick, but was stunned by his skill in the heat of the battle.  It was a tough case and we got the best outcome we could reasonably expect in light of some unanticipated pretrial rulings. My company, my retirement, everything was on the line. If things had gone badly, I would have been in a world of hurt. There was no one I would rather have had to represent me.”  - Chris Heikenen, Chairman and CEO, H&S Manufacturing Co. Inc.

Notable Representations:

  • ​Represented defibrillator manufacturer against competitor and secured $23 million verdict for breach of patent cross-license.
  • Represented souvenir wholesaler and major retailer in trademark/false advertising dispute – invalidated competitor trademarks with no liability. 
  • Represented client in the agricultural equipment industry – while the client was found to infringe a competitor’s patents, the jury awarded the plaintiff a small fraction of what was sought, and substantially less than the competitor was ready to accept as settlement.
  • Represented manufacturer of high-speed data storage testing solutions against multiple infringers – cases settled with seven-figure payment, redesigns of infringing products and no licenses.
  • Represented computer software manufacturer against numerous charges of patent infringement by non-practicing entities – all cases resolved favorably without any payment to plaintiffs.
