Douglas M. Kubehl
Partner | Practice Group Co-Chair - IP Litigation (Firmwide)

Overview

Doug Kubehl serves as the firm's co-chair of its patent litigation department. He is a first-chair trial lawyer with nearly thirty years of experience handling complex patent litigation and licensing in courts throughout the country as well as in Europe and Japan. According to Chambers USA (2022), Mr. Kubehl "is a fantastic attorney who knows the evidence, knows the arguments and is a great writer." Chambers (2022) also describes him as having "a great client approach" and as one who "understands complicated technology and is able to explain it in a common-sense way to others." IAM Patent 1000 (2022) identifies Mr. Kubehl as a "high-powered litigator" and also notes his "expertise in patent licensing" among other areas of intellectual property.

Mr. Kubehl specializes in competitor cases (both as patent holder and on defense) and ultra-complex defenses multi-patent (typically 8 or more asserted) patent cases. Most recently, he led a team in a case defending against 8 asserted patents related to automated driving software. As part of the defense, Doug’s team identified and counter-asserted patents against the competitor. When the dust settled, Doug’s team had defeated all 8 competitor patents before trial and had conducted a two-week jury trial against the competitor. What began as an aggressor case against our client resolved with only the aggressor facing liability and ultimately agreeing to a settlement while the jury deliberated.

Mr. Kubehl has conducted nearly 200 patent cases, receiving jury verdicts of infringement on the patent holder side and non-infringement and invalidity on the defense side, as well as securing over 20 summary judgment rulings of non-infringement. Mr. Kubehl assembles diverse trial teams and is helping to train the firm’s next generation of leading patent trial lawyers. Outside the courtroom, Mr. Kubehl has deep experience in negotiating complex technology agreements.
