Image Processing Technologies LLC v. LG Electronics Inc., decided 29 Jan 25

This non-precedential Federal Circuit opinion affirms a district court's claim construction in a patent infringement case. Image Processing Technologies (IPT) appealed the district court's interpretation of a claim term in U.S. Patent No. 6,959,293, arguing it was broader than the broadest reasonable interpretation applied by the Patent Trial and Appeal Board (PTAB). The Federal Circuit disagreed, finding the district court's construction consistent with the patent's intrinsic evidence (claims, specification, and prosecution history), and rejecting IPT's arguments regarding "common parameter" limitations. The court concluded that the district court correctly determined that the disputed claim term was not unduly broad, affirming the judgment for LG Electronics.
