Douglas M. Kubehl

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, 2015, Mr. Kubehl is regarded as a "very insightful, strategic lawyer," and as an "excellent advocate and team leader." IAM Patent 1000 (2015), describes Mr. Kubehl as a “dyed-in-the-wool litigator” and reports that his peers “hail his rare combination of ‘immense technical expertise and first-rate advocacy skills.” IAM relates that Mr. Kubehl's clients appreciate that “[h]e never raises an issue without also presenting a well-thought-out solution.”

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.
