Oakley Adds to Claim Against Nike

Sunglasses manufacturer Oakley Inc. said Thursday that it has added a patent-infringement claim over lens coatings to a lawsuit it filed against Nike Inc. last year.

In an amended complaint in federal court in Santa Ana, Oakley contends sneaker and apparel giant Nike copied its patented Iridium lens-coating technology in Nike’s sunglasses line. The coating helps cut glare and allows wearers to tailor the glasses’ tint for specific purposes, according to Oakley, which is based in Foothill Ranch.

The original patent-infringement suit, claiming Nike misappropriated Oakley’s XYZ Optics lens technology, remains unchanged, Oakley said. Nike officials weren’t immediately available to comment on the amended complaint.
