Jackson Walker Resolves Preliminary Injunction Request for Principal Lighting Group
Jackson Walker has resolved a patent infringement lawsuit filed by its client Principal Lighting Group, LLC (PLG). The suit was filed in the Central District of California (Los Angeles division) against The Sloan Company d/b/a SloanLED, alleging that SloanLED infringed PLG’s U.S. Patent Nos. 9,311,835, 9,851,054, and 10,024,501, each directed to light-emitting diode (LED) assemblies that can be used to retrofit commercial signs designed for use with fluorescent lamps.
Shortly after PLG filed its complaint, PLG filed a motion for preliminary injunction seeking to enjoin SloanLED from selling its PrismBEAM products as infringing PLG’s ’054 and ’501 Patents and competing with PLG’s Stik™ family of products covered by those patents.
After briefing and further proceedings on PLG’s request for preliminary injunction, PLG and SloanLED reached a resolution whereby SloanLED agreed to redesign its PrismBEAM product in view of the ’054 and ’501 Patents and license the ’835 Patent. The full joint statement of the parties can be found here.
