SunPower and SunLink have settled a patent infringement case brought by SunPower before the U.S. District Court for the Northern District of California. SunPower called the lawsuit against SunLink back in February 2008 asserting infringement of SunPower’s patent rights covering its lightweight rooftop mounting products, SunPower PowerGuard and the SunPower T10 Solar Roof Tile.

The specifics of the settlement remain confidential, yet we do know that SunLink has acknowledged the infringement of SunLink’s MMS rooftop solar product as well as the validity and enforceability of SunPower’s patent rights. SunLink has also received a license to SunPower’s infringed patents for confidential consideration provided under the settlement.
