The Federal Circuit reversed an anticipation ruling by the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board, which had found two claims of a Rambus patent to be “unsupported by substantial evidence.” On June 4, the appellate panel sided with Rambus and reversed the finding.
The Federal Circuit ruling is the latest development in a long-running dispute between Micron Technology and Rambus. Initially, Micron requested the inter partes review of two claims of the Rambus patent, designed to improve a computer’s memory by adding an external clock that synchronizes data transfer timing and provides the ability to delay a transfer by a specific, known amount of time. The Circuit judge decided that “a value cannot ‘represent’ an ‘amount of time’ if there are additional factors, wholly unrepresented by that value, that necessarily impact, or represent, the ‘amount of time.’”
Rambus is represented by Finnegan attorneys.
