Katie O'Sullivan

Katie O'Sullivan is a seasoned patent litigation attorney primarily operating in an in-house defense capacity. She serves as Senior Corporate Counsel, US Litigation at Renesas Electronics, where she manages and supports US-based litigation and disputes across a diverse range of semiconductor technologies. Her responsibilities also encompass the drafting and negotiation of global IP licenses, R&D development projects, strategic sales agreements, and M&A (cite: 1). Her practice centers on defending operating companies, as evidenced by her single tracked appearance on the defendant side and her current role addressing patent assertions from entities often perceived as NPEs (Non-Practicing Entities) (cite: 7).

Her experience in patent litigation is notably focused on the semiconductor industry, stemming from her current role at Renesas and prior experience as an IP Litigation Associate at Kirkland & Ellis, where she handled matters involving semiconductors, online advertising software, and medical devices (cite: 1). A tracked case, Greenthread, LLC v. Renesas Electronics America, Inc., further highlights her engagement in semiconductor patent disputes against patent assertion entities (cite: 1, 10). She also filed a declaration in Koji IP, LLC v. Renesas Electronics America, Inc., another patent infringement suit against her employer (cite: 8). Additionally, Renesas Electronics has been involved in significant trade secret litigation, AMS-OSRAM USA Inc. v.

O'Sullivan's background includes experience at the U.S. Patent and Trademark Office as a patent examiner in the business methods art unit, and she is a registered patent attorney (cite: 1). While specific personal appearances in PTAB proceedings are not detailed, her history as a patent examiner and her role in managing litigation suggest familiarity with post-grant review mechanisms, often leveraged in semiconductor patent defense strategies, as seen in related cases where stays pending IPR were granted (cite: 10).
