ACCO Brands Corp. v. Fellowes, Inc., No. 15-1045 (Fed. Cir. 2016)
Annotate this CaseFellowes obtained the 468 patent, claiming a shredder that prevents paper jams using a combination of a presence sensor that detects whether paper is present in the feed and a thickness sensor that detects whether the stack’s thickness risks exceeding the shredder’s capacity. The patent further claims a controller that turns the shredder motor on only when those sensors indicate paper is present in the feed that does not exceed the shredder’s thickness capacity. Because prior art contained both sensors, Fellowes claimed nonobviousness based on its particular combination of these elements. Fellowes sued ACCO for infringement. The Patent and Trademark Office granted reexamination. An examiner found a prima facie case that certain claims would have been an obvious combination of prior art. The Patent Trial and Appeal Board reversed, finding that the examiner failed to make a prima facie showing of obviousness. The Federal Circuit reversed, holding that the examiner made this prima facie showing, and remanded to allow the Board to consider issues that it did not reach below: whether Fellowes’ rebuttal evidence changes the outcome on obviousness and whether the dependent claims at issue provide independent grounds of nonobviousness.
