Canon lost the case of patent infringement related to sensor technology

CANONFour years ago, in September, 2011 the company Intellectual Ventures filed suit against the defendants Canon Inc. and Olympus Corporation and alleged both the companies for infringement of nine patents.

After long run the United States district court finally accused Canon for utilizing the two image sensor patens of with the patent number of US6, 221,686 for “Method of making a semiconductor image sensor” and another patent number of US6, 023,081 for “Semiconductor image sensor.”

As mentioned in the published document:-

“By Memorandum Opinion entered by The Honorable Sue L. Robinson in Intellectual Ventures I, LLC, et al. v. Canon Inc., et al., Civil Action No. 11-792-SLR (D.Del., May 18, 2015), the Court granted plaintiff’s alternative motion for a new trial regarding infringement of U.S. Patent Numbers 6,121,960 (“the ‘960 patent”) and 5,754,348 (“the ‘348 patent”) after concluding that defense counsel in his closing argument improperly played the role of expert witness by inferring from factual testimony that the accused devices did not meet the claim limitations arguments.  The court found such argument to be contrary to a pre-trial agreement that defendant would not present any evidence of non-infringement, including evidence of a lack of a subjective intent to infringe, particularly given that the Court previously barred certain testimony from plaintiff’s witnesses on the topic during the trial.”

At last the court made the decision in favor of Intellectual Ventures.
