Corey Johanningmeier

Partner

Corey specializes in complex intellectual property litigation, with a long record of success both asserting and defeating patent claims on behalf of startups, individuals, universities, and Fortune 500 companies. He has served as actual or de facto lead counsel, driving strategy from complaint through successful resolution. And he has often stepped in to manage technical or other aspects of ongoing cases. In particular, he has substantial experience working with, presenting, and cross-examining engineer and expert witnesses. A trial lawyer at heart and in actual practice, Corey works efficiently and with judgment born of wide experience. He writes and argues with clarity and credibility—having found more success with honest teaching than in any other form of advocacy to juries and judges.

Prior to joining Bunsow De Mory, Corey gained over a decade of experience trying, litigating, and resolving high-stakes intellectual property cases at Keker, Van Nest & Peters and at Jones Day. In addition to his many stand-up trial experiences in U.S. District Courts around the country and at arbitration, Corey tried three misdemeanor cases to jury verdict as a volunteer Deputy District Attorney in Los Angeles. He has also represented indigent clients pro bono in civil, family, traffic, eviction, and immigration courts, and in the U.S. Court of Appeals.

Corey had a whole previous career in electrical and computer engineering, before taking a hint from his childhood fascination with Perry Mason. He worked as a chip designer and technical marketing engineer on mixed-signal and very-large-scale integrated circuits—for disk drives, optical routers, network processors, and other applications. In his free time, he takes road trips, reads towards achieving polymathy, and tries to be a good Dad.
