Veteran IP litigator David Bloch is moving his practice to Greenberg Traurig after 13 years with Winston & Strawn.

Bloch is the co-author of “IP and Technology in Government Contracts.” While at Winston he helped the firm score a Supreme Court win for generic pharma in the patent case Caraco Pharmaceutical Laboratories v. Novo Nordisk.

Bloch said he has nothing but good things to say about Winston and his colleagues there, but couldn't pass up the opportunity to join Greenberg, which with nearly 2,000 lawyers across 40 offices, has about double the footprint.

“It felt like it an opportunity I couldn't say no to, so at the end of the day I didn't say no,” said Bloch, who will join Greenberg's San Francisco office Monday.

Adding to the appeal was that former Winston colleagues, such as Charles Birenbaum and Bradley Marsh, now practice at Greenberg. Bloch also worked with Greenberg partner L. Scott Oliver when the two were starting out at Gray Cary Ware & Freidenrich.

“I feel as if I'm going to a place where I've already got friends and even a network,” Bloch said.

Birenbaum said he knows Bloch's capabilities well, having recruited him to Winston when he was the firm's San Francisco managing partner. “David is a seasoned litigator in a broad range of IP litigation,” Birenbaum said. He “adds to a growing NorCal center of gravity in that space after our recent addition of Scott Oliver.”
