Three months after, Apple has filed a countersuit that accuses the film and imaging company of violating two of its own digital photography patents.
Apple accused Kodak of infringing patent 6,031,964, a "system and method for using a unified memory architecture to implement a digital camera device," and patent RE38,911, a "modular digital image processing via an image processing chain with modifiable parameter controls," according to details from the suit posted at Patently Apple.
Apple filed its suit in the federal court for the northern district of California on Thursday. Kodak had filed two suits in January accusing Apple of violating three Kodak patents. They were the latest in a series of patent infringement suits Kodak has brought against technology companies.
Update 4:37 a.m. PST: Kodak didn't comment on the particulars of the Apple case, but said: "As regards our intellectual property, Kodak has a long history of digital imaging innovation and we have invested hundreds of millions of dollars creating our industry-leading patent portfolio. We have an obligation to our shareholders and the other licensees to protect their interests. When others use our technology, we merely seek fair compensation for that use, in the same way that many other leading technology companies pay us to license Kodak technology."
