We represented a law firm and individual attorneys in a highly contentious and complicated case brought by a developer alleging legal malpractice claims against our clients, along with numerous claims against a large group of other individuals and companies involved in a real estate joint venture. We executed an aggressive defense strategy, using early discovery and motion practice, to quickly extricate our clients from the dispute. We secured dismissal for waiver of costs for all the individual attorneys and a favorable early settlement for the law firm.
We represented SanDisk in a massive trade secret misappropriation and corporate espionage case. SanDisk, a global leader in flash memory storage solutions, sued competitor SK Hynix for misappropriating approximately ten gigabytes of highly confidential trade secret information and using that information over the course of six years to revamp Hynix’s technology and unfairly compete with SanDisk. We obtained a sweeping preliminary injunction that barred Hynix from any further use or disclosure of stolen SanDisk information, and fought back efforts to dismiss the case, to send it to arbitration, to transfer it overseas, and to remove it from the court that granted the preliminary injunction. Following a series of courtroom victories for our client, the parties reached a confidential settlement and entered into a product supply agreement.
In this putative securities class action, the plaintiff accused our client, a renewable energy company, of knowingly making false and misleading statements over the production of a chemical used in transportation fuels. After we demonstrated the company was simply mistaken in their projections and its statements provided meaningful cautionary warnings, the judge granted our motion to dismiss.
We successfully defended in arbitration a top law firm and one of its partners against a multi-million dollar malpractice claim related to estate planning. We were able to get the case dismissed on statute of limitations grounds and also obtained attorneys’ fees on behalf of our client.
On behalf of the ACLU and other amici, we submitted a brief challenging the San Diego District Attorney’s refusal to offer juveniles the benefit of sentencing reforms made available by Proposition 47. We argued that the DA’s position contravened voter intent and violated juveniles’ equal protection rights. The Court of Appeal for the Fourth District agreed, ruling that Proposition 47 should apply equally to juveniles and adults. The court’s decision is now binding on trial courts across California, and the sentencing relief afforded will help thousands of young people access better opportunities in education, employment, and the military. It also ensures that they face less severe penalties in future criminal or immigration proceedings.
