No infringement in camera patent dispute
Ampex Corp. v. Eastman Kodak Co. et al., No. 04-1373-KAJ, Oct. 31, 2006.
Jordan, J. Defendants’ motion for summary judgment of non-infringement is granted.
The technology relates to digital cameras. Defendants claim their cameras do not store, for later access, the same “data” that was initially received and used to generate a reduced size image. Their cameras perform significant processing which changes the pixel values of an image before it is stored in permanent memory. The court found there was no literal infringement, and did not need to address other contested limitations. Prosecution history estoppel prevents the doctrine of equivalents from being applied to the “said data” element in amended claims.
