Denise Marie De Mory

Denise Marie De Mory is the managing partner and co-founder of Bunsow De Mory LLP, an intellectual property litigation boutique based in Silicon Valley. Her practice focuses on complex patent and intellectual property disputes across various technology sectors, including life sciences (such as CRISPR RNA synthesis technology), mobile communications (e.g., 3G technology), telecommunications, artificial intelligence, fintech, software e-commerce, and computer science. She also handles matters involving trade secrets, trademarks, copyrights, and data security.

While the provided case data shows a balanced mix of plaintiff (4) and defendant (3) representations, Ms. De Mory's firm explicitly states a focus on plaintiff-side patent cases, securing significant verdicts and settlements for patent holders. She has extensive trial experience, having litigated over 150 patent and intellectual property cases and tried more than a dozen to verdict. Notable outcomes include leading the trial team that secured a $110.7 million jury verdict for TOT Power Control, S.L. against Apple, Inc. in June 2025, concerning 3G technology. Additionally, she was lead counsel in a September 2023 trial for ViaTech Technologies, Inc. against Adobe, Inc., where a jury initially awarded nearly $33.8 million for software patent infringement, though a judgment notwithstanding the verdict was later granted. She was also a key player on the U.S. Department of Justice's team in the U.S. v. Microsoft antitrust litigation.

Ms. De Mory possesses substantial experience with the Patent Trial and Appeal Board (PTAB) and the U.S. Court of Appeals for the Federal Circuit, having litigated dozens of inter partes review (IPR) petitions. Her firm, Bunsow De Mory, was recently ranked as a top-performing law firm at the PTAB. She successfully defended Theta patents against Lenovo's IPR challenges at the PTAB, upholding patent validity. She also represented Agilent Technologies, Inc. in IPRs and subsequent appeals against Synthego Corp. concerning CRISPR RNA synthesis patents, which ultimately resulted in the patents being found unpatentable by the PTAB, affirmed by the Federal Circuit, and certiorari denied by the Supreme Court, leading to dismissal of related district court actions for mootness.

She is admitted to the State Bar of California, the U.S. Court of Appeals for the Federal Circuit, and the Supreme Court of the United States, among other federal courts. She earned her J.D. from John Marshall Law School and her B.A. from the University of Illinois.
