Work highlights
Secured a landmark First Amendment victory for Jenner & Block, defeating a retaliatory executive order issued by President Trump that sought to punish the firm for its client advocacy.
Defended Google in two high-stakes jury trials involving novel privacy and data-use theories. In Csupo v. Google, plaintiffs sought $1.25 billion over claims that Android’s data transmission constituted tortious conversion of cellular data plans. In Rodriguez v. Google, statutory and punitive claims under California’s CDAFA were defeated, and recovery was limited to a fraction of the $30+ billion sought, despite findings on certain common law claims. Both verdicts are on appeal.
Secured a landmark fair use victory for Meta in one of the first US copyright cases challenging generative AI model training. The court held that Meta’s use of copyrighted works to train its LLaMA model was “highly transformative” and caused no market harm, dismissing all copyright and DMCA claims.
