SAN FRANCISCO — Life sciences cloud computing company Veeva Systems Inc. has sued three rivals, claiming the noncompete agreements they force employees to sign violate California law.

The company’s lawyers, Chris Baker and Deborah Schwartz of Baker Curtis & Schwartz in San Francisco, filed a declaratory judgment lawsuit in Alameda County Superior Court Monday seeking a ruling that its competitors’ noncompete agreements illegally restrain trade in violation of California law. Veeva has taken a prominent, public stand against noncompete agreements in the life sciences industry, but the lawsuit seeks to put its rivals and their noncompete agreements on the defensive.
