Cases of Note
Taiwan Semiconductor Manufacturing Company v. Semiconductor Manufacturing International Corporation: We represented TSMC against China's then-leading semiconductor manufacturer, SMIC, in the largest trade secret misuse case tried to date. SMIC owed its very existence to technology stolen from our client. Following a jury verdict on liability in favor of TSMC, SMIC agreed to pay $200 million in cash and approximately $130 million of its company stock. The case serves as precedent for the strong protection afforded by California's trade secret statute, even where the actual theft occurred in Asia.
Purdue Pharma v. Impax Laboratories, Inc.: We defended Impax Laboratories, Inc. against patent claims related to generic oxycodone products. Following the Federal Circuit’s reversal and remand of inequitable conduct findings in an earlier lawsuit brought against another defendant, we brought a revised challenge under the terms of the Federal Circuit’s order. We then secured a settlement that released our client from all past liability, and gave the company a limited license.
Ziptronix v. Taiwan Semiconductor Manufacturing Company: We won summary judgment of non-infringement for Taiwan Semiconductor Manufacturing Company, Ltd. and its subsidiary TSMC, North America in a long-running patent lawsuit brought by North Carolina semiconductor company, Ziptronix, Inc. Ziptronix had asserted nine patents and more than 500 patent claims directed to TSMC’s manufacturing of semiconductors for use in backside-illumination image sensors used predominantly in smartphone cameras. On behalf of TSMC, we defeated Ziptronix’s claims by arguing that the territorial limits of U.S. patent law prohibited reaching TSMC’s business transactions and manufacturing operations in Taiwan.
Eastman Kodak Co. v. HTC Corp.: We defended HTC in a five-patent investigation brought by Kodak before the International Trade Commission. The action accused dozens of mobile devices of infringing digital imaging patents that covered a range of technologies, including image capture, processing, display, compression and transmission. Consistent with ITC practice, our defense took place on a fast schedule, with a hearing date that was set approximately one year from the start of the investigation and fact discovery being completed in approximately six months. Just prior to the scheduled hearing date, the case was resolved when the Kodak patent portfolio was sold.
Securities and Exchange Commission v. Former Chief Financial Officer: We defended the former chief financial officer of a San Francisco-based hedge fund firm against charges of insider trading. The case was part of the government’s push to make insider trading the focus of financial fraud prosecution. The Securities and Exchange Commission named our client and several others in a civil suit, alleging they made more than $8 million trading on stocks based on insider tips. We knocked out half of the case on summary judgment and settled the remainder on very favorable terms.
Securities and Exchange Commission v. Chief Executive and Chief Financial Officers: We represented the CEO and CFO of a communications technology company in a Securities and Exchange Commission (SEC) investigation, a lawsuit filed with the SEC, related civil lawsuits filed by investors, and a related bankruptcy action. We resolved all of the lawsuits on favorable terms.
United States v. McKesson Corporation: We won a complete defense judgment in favor of a major medical supply company after a month-long trial of a qui tam action alleging violations of the False Claims Act and Anti-Kickback Statue. This victory was listed by the National Law Journal as one of the year's five most significant trial wins.
Plaintiff v. Law Firm: We successfully defended at trial an Am Law 50 law firm and one of its former partners against a $100 million claim. The plaintiff alleged malpractice and breach of fiduciary duty related to estate planning. After an eight-week trial in California state court, we won a complete victory.
Plaintiffs v. Individuals: Plaintiffs filed breach of contract and many other state claims including fraud and unjust enrichment against our clients. We successfully filed a demurrer on more than half of the claims, eventually leading to a successful settlement.
Plaintiff v. Westamerica Bank: We successfully tried this breach of contract lawsuit, filed in Solano County Superior Court. We won a favorable verdict for the plaintiff on the liability phase.
