PRESIDENT
Adam Powell | 858.707.4000 | adam.powell@knobbe.com
Partner, Knobbe Martens LLP.
Adam Powell has a broad practice that involves litigating all types of intellectual property cases, including patent, trade secret, copyright, and trademark matters. He also has extensive experience litigating antitrust matters, particularly those involving technologically complex issues. Adam works with various technologies, including medical devices, software, electronics, chemistry, biotechnology, solar energy, and commercial diving.
In one of his most successful cases, Adam represented Masimo Corporation in a three-week trial against Philips. The jury awarded $466 million to Masimo and rejected Philips’ infringement claims seeking $169 million. That verdict was featured in The National Law Journal‘s “Top Verdicts of 2014” as the top intellectual property verdict and number 5 verdict overall and was also listed as the “Top IP Award of 2014” by Law360. After the jury trial, Adam was responsible for defending against Philips’ antitrust counterclaims alleging patent misuse, monopolization, attempted monopolization, and technological tying. The litigation eventually settled with Philips paying Masimo $300 million and agreeing to a multi-year joint marketing and sales program in which Philips would integrate Masimo technologies in its patient monitors.
