Nikon is being sued for alledgedly infringing four patents related to digital camera technology

Bloomberg reports that Intellectual Ventures LLC has sued Nikon for patent infringement on four different digital camera technology patents:

"IV said it initially approached Nikon in 2008 about taking a license to the patents. Nikon declined to meet with the technology-licensing company at that time, according to court papers.

In 2011, IV said it made a second approach to Nikon and its “good-faith efforts to negotiate a license” with the camera company failed."

The four patents in question can be found here:
