Rimon PC partner trio exit firm to launch Silicon Valley IP boutique

Founding partners joined by three former Rimon lawyers and support staff amid wave of US lateral IP activity


Three Rimon PC partners have left the firm to launch KXT Law, a six-lawyer commercial litigation and intellectual property boutique in Silicon Valley. 

Karineh Khachatourian, David Xue and Amir Tabarrok are spearheading the venture with three more lawyers and three support staff. The six lawyers have worked together for more than a decade, with their collective expertise spanning a range of IP issues tied to the Bay Area’s tech, mechanical and entrepreneurial markets. 

The trio set up the boutique in response to client demand for something other than a ‘one-size-fits-all’ approach to IP and commercial litigation matters, KXT Law said.  

Khachatourian, who is serving as KXT Law’s office managing partner, joined Rimon in 2018 as the firm’s office managing partner in Palo Alto. Before that, she was a founding member of Duane Morris’ Silicon Valley office, where she served as office managing partner between 2013 and 2018. 

Rimon did not immediately respond to a request for comment on Khachatourian’s replacement. 

“We are connected to the legal, technology and inventor communities and committed to our calling to acquire, manage, enforce and protect quality intellectual property for all our clients and defend them against intellectual dishonesty,” Khachatourian said. 

Xue and Tabarrok jumped to Rimon from Duane Morris with Khachatourian in 2018. Xue specialises in patent-related matters in the tech sector, while Tabarrok focuses on drafting and prosecuting patent applications in the electrical, mechanical and computer software fields.

For its part Rimon, a tech-driven distributed law firm based in Silicon Valley, has been rapidly expanding its global footprint over the past few years. 

The firm launched in Orlando in June and last September added a pair of finance partners from Bryan Cave Leighton Paisner to set up shop in Frankfurt, the firm’s seventh office launch in 2021 after Seoul, Casablanca, Paris, London, Austin and Montreal. The firm was started in 2008 but saw rapid growth during the Covid-19 pandemic and now has more than 45 locations around the globe.

Several other US law firms have added significant IP heft from national rivals as of late, including McDermott Will & Emery, which last week hired eight IP partners from Baker Botts to launch an office in Austin

And Fox Rothschilds opened an office in Boston with a group of IP lawyers from Mintz Levin in May, while Womble Bond Dickison hired a five-lawyer IP group from Abelman Frayne & Schwab to launch its 20th US office in New York in April.
