Edward Kwok, Jennifer Lantz, Steve Levitan and Clark Stone join from Haynes and Boone and will be based in Hogan Lovells’ Silicon Valley office. Christian Mammen was an associate with Heller Ehrman and partner of Day Casebeer Madrid & Batchelder before working as a sole practitioner. He will be based in Hogan Lovells’ San Francisco office.
Mammen was one of six lawyers acting for Qualcomm censured by a judge in 2008 over their client’s failure to produce documents during the discovery process in litigation with Broadcom. The Court later ruled that there was insufficient evidence to prove that any of the six attorneys had operated in bad faith and declined to impose sanctions on them.
The five new partners will focus on IP litigation in the US courts and at the International Trade Commission, predominantly for technology clients from the US west coast and Asia.
Earlier this month the firm hired commercial trial lawyers Mark Goodman and Ethan Miller from Squire Sanders to help it win more cross-border litigation work from clients in the pharmaceutical, consumer product and energy sectors. The two are based in Hogan Lovells’ San Francisco and the Palo Alto offices. Last year a team of five IP litigation partners, led by Sunny Cherian and Scott Wales, joined the IP practice in the San Francisco office from Howrey.
