OpenAI tapped Keker as lead trial counsel in a series of copyright lawsuits that will establish the boundaries of copyright fair use as applied to generative AI. The cases include claims brought by newspapers, authors, and other media outlets alleging that the training of Open AI's large language models infringe their works.

We defended a prominent law firm and one of its senior partners against legal malpractice and fraud actions in California federal court, Los Angeles Superior Court, and U.S. Bankruptcy Court. The firm had served as tax opinion counsel in connection with a series of tax-sheltered investments in a solar business that turned out to be a Ponzi scheme. After years of litigation, we negotiated a successful settlement between the firm and the solar company investors. We also negotiated a successful settlement between the law firm and the Trustee for the consolidated estates of the company and its subsidiaries.

We represented a former law firm partner in settling a fraud action brought by the government of Denmark in the Southern District of New York. The case involved claims that the lawyer set up pension plans and assisted them in purporting to invest in, and then unwinding, transactions in dividend-paying Danish companies to obtain a half-billion dollars’ worth of tax refunds, thereby defrauding Denmark’s tax authority.
