July 7 (Reuters) - Neel Chatterjee, a technology lawyer

whose clients have included Facebook, Oracle and LinkedIn, has

left law firm Goodwin Procter to join rival King & Spalding, his

new firm said on Monday.

Chatterjee, a Silicon Valley-based partner who helped

organize opposition among law firm partners to U.S. President

Donald Trump's actions targeting the legal industry, is joining

King & Spalding's business litigation group and will co-lead its

intellectual property team, the firm said.

Chatterjee in April helped create Law Firm Partners

United, a group that now includes more than 800 members from the

200 largest U.S. firms by revenue.

The non-profit association filed friend-of-the-court briefs

backing law firms Susman Godfrey, and Jenner & Block in their

lawsuits challenging Trump's executive orders against the firms.

Federal judges have blocked the orders permanently.

The group also filed a brief in support of lawyer Mark

Zaid in his lawsuit challenging the Trump administration's

decision to revoke his U.S. security clearance. Zaid represented

a government whistleblower in a case that led to Trump's

impeachment during his first term.

Chatterjee had no immediate comment. A Goodwin

spokesperson said the firm appreciated his contributions.

Among his prominent cases, Chatterjee represented Facebook

and its founder Mark Zuckerberg in a legal battle with former

Harvard classmates Cameron and Tyler Winklevoss. Their battle

was dramatized in the 2010 film "The Social Network."

Other clients have included former Google engineer Anthony

Levandowski, as well as NVIDIA ( NVDA ), eBay ( EBAY ) and Logitech, according to

King & Spalding.

Chatterjee joined Goodwin in 2017 and previously served on

its executive committee.
