Permlight Products has filed a patent infringement lawsuit against Electraled in the United States District Court for the Central District of California.
Headquartered in Largo, Florida, Electraled produces LED illumination products for the sign market.
The lawsuit alleges that Electraled's "FLEX" LED system infringes Permlight's patents, including US patent no. 6,712,486 entitled "Mounting Arrangement for Light Emitting Diodes" and US patent no. 6,846,093, entitled "Modular Mounting Arrangement and Method for Light Emitting Diodes".
The patents are related to Permlight's popular RL, SL, DL, DL2, DL3, DSL, PaletteLight, PaletteLight MINI. Twister and EL Blanco White LED product families.
The complaint requests damages and an injunction against infringement.
Permlight has instigated a number of patent lawsuits against its competitors. In December 2004, a settlement was reached between Permlight and Tempo Lighting in a lawsuit dating back to April of that year.
Permlight also settled a lawsuit against US LED in August 2004. |
