Jiaxing Super Lighting Electric Appliance Co. Ltd., et al. v. CH Lighting Technology Co. Ltd., et al.

Analysis Group was retained on behalf of Jiaxing Super Lighting Electric Appliance (Super Lighting) and Obert, Inc. (Obert), Super Lighting’s US subsidiary, the plaintiffs in a patent infringement dispute brought in the US District Court for the Western District of Texas against CH Lighting Technology (CH Lighting), a rival lighting company; Shaoxing Ruising Lighting (Ruising), CH Lighting’s subsidiary; and Elliott Electric Supply (Elliott), a Texas-based electrical parts distributor. Super Lighting alleged that the defendants manufactured, imported, and sold LED tube lamps that infringed three of its patents, and sought royalty damages. At issue in the case were the validity of all the asserted patents and infringement with respect to one of the asserted patents.

An Analysis Group team led by Vice President Tom McGahee supported Managing Principal Lauren Kindler in her work assessing Super Lighting’s royalty damages resulting from the defendants’ infringement. Ms. Kindler filed an expert report and testified at deposition and trial.

Judge Albright of the Western District held that one of the contested patents was valid in a directed verdict. A jury then found in Super Lighting’s favor, holding that the remaining patents were valid and infringed by all three defendants, and that willful infringement had been proven with respect to Ruising and CH Lighting. Based on Ms. Kindler’s damages opinion, the jury awarded damages in the amounts of $13.9 million for CH Lighting and Ruising, and $298,000 for Elliott.
