Christie Parker & Hale LLP in Glendale announced Monday that it has merged with Phoenix’s Lewis Roca Rothgerber LLP to become Lewis Roca Rothgerber Christie LLP.

The combined law firm will specialize in intellectual property law as well as prosecution and litigation for patents, trademarks and copyrights.

From individual inventors to Fortune 500 companies, the practice represents a wide range of clientele both international and domestic. The combined firm will have almost 300 lawyers working throughout Arizona, California, Colorado, Nevada and New Mexico.

“Lewis Roca Rothgerber already had a solid reputation in its core practices of IP, litigation, business transactions, government relations and gaming, especially the substantial litigation experience that our clients need,” Greg Lampert, managing partner at Christie Parker said in a statement. “Both legacy firms share a deep commitment to client service, and this is a seamless fit strategically, culturally and professionally.”

Prior to the merger, Christie, Parker & Hale had over 40 lawyers in Southern California, while Lewis Roca Rothgerber had approximately 250 attorneys in Phoenix, Las Vegas and the Southwest region.

Currently, all offices remain at their existing locations.
