The Federal Circuit overturned a $13.9 million patent verdict against Jiaxing Super Lighting Electric Appliance Co., citing errors by a Texas court that limited the defense’s ability to present evidence and failed to properly evaluate the damages expert’s testimony. The case stemmed from CH Lighting Technology Co.’s alleged willful infringement of three Super Lighting patents, which led to a doubled damages award by Judge Alan Albright. CH’s appeal contended that the judge did not allow its witness to authenticate photos demonstrating that Super Lighting marketed tube products containing elements claimed in the patents.
