William Alderman Senior Counsel

San Francisco

Bill is additionally recognized for the results he has obtained in insurance coverage, employee benefits, and federal and state antitrust disputes. He commits a substantial part of his time to pro bono representation and to representation of the firm.

Representing clients in class and derivative actions, Bill's approach is to minimize his clients’ overall cost through careful strategic planning, dispositive motions and aggressive negotiation. Only three of the many securities class actions he has defended have resulted in any settlement payment by his client or its carrier. Of his nearly 100 motions to dismiss securities class, mass or derivative actions since 1996, more than 90 percent were granted in their entirety (most with prejudice), while others were granted in part or led to a successful motion for summary judgment.

Peter Bicks Partner

New York

In recognition of Peter’s career trial work, he was inducted into the American College of Trial Lawyers in 2015. Juries have compared him favorably to Johnnie Cochran and F. Lee Bailey. Clients laud Peter, telling Chambers USA 2020-2022, “He’s a standout trial lawyer and an outstanding advocate overall. He appreciates the client’s needs and advocates for them everywhere.” Another client notes, “He is brilliant in the courtroom under the most intense pressure,” “a master of seeing the full chessboard.” That praise is echoed by sources saying, Peter is “one of these lawyers that really turns big cases; he’s a real trial lawyer,” and calling him “one of the most gifted trial lawyers that I have ever seen.” Clients go on to applaud his trial experience and strategic approach saying, “Peter really knows his way round a courtroom. He's a great trial tactician.” “He is an outstanding advocate who appreciates the client's needs and reputational questions involved.” A peer in the trial bar told Law360, “What is most impressive is his ability as a true Field General – calmly directing his team’s efforts.”

With precedent-setting trial wins in intellectual property, commercial and products liability litigation, Peter has amassed honors from annual top rankings in Chambers USA, Legal 500, and Benchmark Litigation, to awards for excellence, such as New York “Litigation Star,” “Law360 MVP,” “Litigator of the Week,” and “Top 100 Trial Lawyers in America.”

It is Peter’s versatility that sets him apart. He brings a combination of deft courtroom skills, strategic acuity and team leadership. In July 2023, a leading company in the biotech agricultural space, Corteva Agriscience, retained Peter as lead trial counsel in a high profile intellectual property lawsuit Corteva filed against Inari Agriculture, Inc. and Inari Agriculture NV to protect its highly valuable patent protected genetically modified seeds. As noted in the complaint, the lawsuit "…seeks to prevent Inari from continuing its brazen efforts to steal Corteva's groundbreaking work." Specifically, the lawsuit alleges that Inari deliberately used a third-party agent to obtain protected Corteva seeds, illegally exported the seeds out of the United States, made slight genetic modifications of the biotech traits and is seeking U.S. patents for those modified traits. The case is pending in the U.S. District Court, Delaware and is in discovery. In May 2022, when faced with a headlining trial over control of the leading international model and talent company, Elite Worldwide Group, the company and its Chairman tapped Peter as lead trial counsel to parachute in just 45 days before trial. Our complete trial win for the client earned Peter and the team Litigators of the Week Runner-Up honors from the American Lawyer. Louis Dreyfus Company turned to Peter recently as lead trial counsel once they saw that a massive, high stakes trial was on the horizon with over $1 billion at stake amid class action claims alleging manipulation of the cotton futures market. DISH Network brought Peter in shortly before trial when the FTC and various state attorneys general sought $700 billion in damages and penalties for alleged telemarketing violations. He achieved an astounding trial victory for DISH limiting recovery to less than one percent of the exposure. For Johnson & Johnson, Peter has been part of a small group of market-leading outside counsel overseeing the defense of more than 15,000 talc-related cases, including product liability trials, consumer class actions, and cases brought under California’s Prop 65; handling multiple trials, SEC, DOJ, and AG investigations; and representing senior executives in major depositions, at trial, and before Congress.

Peter served as co-head of the firm's Global Litigation practice and is a former member of Orrick’s Board and Management Committee. Before joining Orrick, Peter was a partner at Donovan Leisure. He captained his college tennis team to a national ranking, has successfully competed in major national sailboat competitions, and serves on the Board of the Harlem Junior Tennis and Education Program. With his wife Linda, he has three children: Avery, Isabelle and Phoebe.
