Sports gear and sunglasses maker Oakley is not taking imitation as a form of flattery. The Orange County-based company sued e-commerce website Newegg Inc.on Tuesday for patent and trademark infringement, alleging Newegg has been selling knock-off products that use Oakley’s technology, design, and branding.

Represented by Irvine-based intellectual property law firm Knobbe, Martens, Olson & Bear, Oakley is seeking compensation and an injunction barring Newegg from selling high-tech sunglasses that it contends step on several patents or that feature Oakley’s trademarked “O” symbol.
