Elon Musk’s Solar City (SCTY) has been accused of intellectual property theft by Cogenra Solar, a wholly owned subsidiary of SunPower (SPWR), and Khosla Ventures.
In a lawsuit filed in San Francisco on Monday, the parties accused Solar City of gaining undue advantage of Cogenra’s Shingling technology that helps in manufacturing high-efficiency commercially viable solar panels.
Solar City and its subsidiary Silevo misappropriated Cogenra’s trade secrets, manufacturing processes, and other intellectual property to give themselves a competitive advantage and head start in developing shingled-cell solar modules, Cogenra said in the lawsuit.

Solar City said that last week it discovered that a former Solar City employee had unlawfully downloaded confidential information, copied that information to a personal hard drive, and then joined SunPower as a senior sales manager.
“Any unauthorized copying and use of this information is a very serious violation of Solar City’s intellectual property rights so we immediately notified SunPower,” Solar City said in a statement.
Cogenra’s complaint fails to identify any actual trade secret that Cogenra owns, much less that Solar City supposedly misappropriated, Solar City said.
From 2009 to 2015, venture capital firm Khosla Ventures owned about 80% of Cogenra, the lawsuit stated.
Last week Tesla said its proposed acquisition of Solar City could be delayed because of shareholder lawsuits alleging board members breached their fiduciary duty.
