In Knauf Insulation, Inc. v. Rockwool International, the U.S. Court of Appeals for the Federal Circuit vacated and remanded the Patent Trial and Appeal Board’s determination in an inter partes reexamination that certain patent claims for two of Knauf’s patents covering fibrous products and related methods and binder and fiber glass products were obvious. The Court also found that certain other claims of the two patents were not unpatentable as obvious, and Rockwool International cross-appealed that determination, but the Court held that Rockwool did not have standing to cross-appeal and thus dismissed it. The decision was not precedential, but some have commented that the Court’s holding with respect to Rockwool’s lack of standing for a cross-appeal could have significant implications.
