Federal Circuit rules Rambus semiconductor memory patent not anticipated

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.” The appellate panel sided with Finnegan client Rambus and reversed the finding. The Federal Circuit ruling is the latest development in a series of reexaminations requested by Micron.
