Tod Cohen, former Twitter Inc. deputy general counsel, has joined O’Melveny & Myers as a partner after nearly two decades in-house with technology companies.

Cohen said he’s returning to private practice to work on the complex legal matters corporations typically ship to outside firms. His practice areas at O’Melveny will include corporate & transactional, emerging companies, Internet of Things, mergers and acquisitions, and technology.

“Data protection is one area where the outside counsel are the folks that are really involved,” Cohen told Bloomberg Law, also mentioning competition and antitrust. “In my own practice, in many instances, we would sent the best things outside.”

Cohen brings to O’Melveny his reputation for internet and data privacy law—areas that have gained prominence during the Covid-19 pandemic. He started working on internet law at Covington & Burling in the mid 1990s, where he helped clients set up their first websites on the World Wide Web.

Cohen was “‘present at the creation’ of now-foundational internet law,” C. Brophy Christensen, O’Melveny corporate department co-chair, said in a statement Tuesday.

Cohen left his most recent role as deputy general counsel and vice president of Twitter last April, where he managed multiple areas, including antitrust probes.

Before Twitter, he was the general counsel at ticket resale company StubHub Inc. and deputy general counsel of e-commerce platform eBay Inc. Cohen has also worked for the Motion Picture Association of America.

He said the Covid-19 pandemic has led to privacy issues such as the growth of video conferencing and international content sharing. Privacy law will become more challenging in 2021 as the vaccine rollout continues, Cohen said.

“We’ve got a need to build out our vaccination and electronic records, all the time working to make sure privacy is maintained,” Cohen said. “That would be one of the areas that I would want to very much be involved with, if there’s a client need.”

Cohen is based in O’Melveny’s Washington office and is awaiting admission to the California bar.
