Doug Kubehl's practice focuses on complex patent litigation and licensing in courts throughout the country as well as 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 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.

In the wireless space, Mr. Kubehl recently has received a jury verdict of infringement of seven patents in a competitor case, summary judgment of noninfringement with respect to Acacia's vaunted Adaptix portfolio, summary judgments of noninfringement and invalidity with respect to Intellectual Ventures' portfolio of LTE patents, and summary judgment of noninfringement of Iridescent Networks' patent allegedly covering all Voice Over LTE networks. Mr. Kubehl regularly undertakes joint representations of the wireless carriers where the carriers are accused based upon their use of common third party products. And in cases where Mr. Kubehl represents less than all of the defendants, he has been nominated to present on behalf of the group of multiple defendants, both at the district court and at the Federal Circuit Court of Appeals. Outside of the courtroom, Mr. Kubehl has deep experience in negotiating complex technology agreements.

Mr. Kubehl is a registered patent attorney with degrees in Electrical and Computer Engineering and experience involving a variety of technologies, including electronics, telecommunications services, internet technologies, wireless and wireline networking equipment and software, computer hardware and software, semiconductors and optical systems and components. He has considerable experience in the valuation and strategic development of IP portfolios. This experience, along with his work in evaluating and negotiating patent license agreements, gives Mr. Kubehl a broad perspective that facilitates the multi-faceted needs of his clients.
