Nikon seeks $154m from Sigma in patent suit
Digital camera maker Nikon announced on its website that it has filed a patent infringement lawsuit against the Sigma Corporation in a Japanese court on Tuesday. At issue is Sigma's manufacture and sale of lenses for SLR cameras that have a vibration reduction feature built-in. Nikon hopes to get the Tokyo District Court to impose an injunction against Sigma, as well as about $154 million in damages.
Nikon argued Sigma used its intellectual property without permission and tried to negotiate, but couldn't find a non-adversarial solution. Sigma hadn't directly responded to the claim.
Sigma is better known for its lenses for cameras like Nikon's and others rather than cameras, though it makes a handful of high-end models like the SD1.
