A US judge has slashed a legal award Apple was set to collect in its patent infringement case with Samsung.
Judge Lucy Koh ruled that $450.5m of the verdict awarded to Apple will be cut over concerns that key testimony in the case was not permissible.
According to a report from Bloomberg, Koh said that the original verdict which a jury had awarded in favour of Apple relied on testimony which she had instructed them was inadmissible. Despite that instruction, the jury decision appeared to be based on that testimony, Koh ruled.
The ruling cuts a large chunk off of what had been a significant legal victory for Apple. The company claimed victory in August of 2012 when a jury ruled that Samsung had infringed on a number of Apple patents related to the design and operation of mobile devices.
Koh's ruling further cuts into Apple's expected legal reward in the patent infringement case. The company had previously sought to claim damages upwards of the original verdict in a claim which was also shot down.
Apple and Samsung have long been tied up in legal wrangling over allegations of copyright infringement between the iOS and Android platforms. In legal filings around the globe, each company has accused the other of violating intellectual property holdings and sought orders banning the import of hardware.
