The US Court of Appeals for the Federal Circuit has remanded  a patent infringement claim against technology companies including Huawei and Samsung to a district court.
In a decision handed down on March 3, the court altered a claim construction but added that the “minor modification” is unlikely to affect the outcome of the case.
In 2014, Technology Properties accused Huawei, Samsung, ZTE, LG and Nintendo of infringing US patent number 5,809,336, in five separate lawsuits filed at the US District Court for the Northern District of California.
Although the parties agreed to the first half of the construction, Technology Properties disputed the portion called “that does not require a control signal and whose frequency is not fixed by any external crystal”.
Technology Properties appealed and the Federal Circuit consolidated the appeals.
Because the district court erred in a portion of its construction, the Federal Circuit vacated and remanded the suit.
