From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

Multilayer Stretch Cling Film Holdings, Inc. (“Mult i- layer”) brought suit against Berry Plastics Corp. (“Be r- ry”), alleging infringement of at least claim 1 of U.S. Patent No. 6,265,055 (“the ’055 patent”), which relates to multilayered plastic cling wrap films . The district court construed the claims of the ’055 patent as not covering (i.e., closed to) blends of the four resins expressly recited by those claims or unlisted resins, instead requiring that each of five inner layers within the film be composed of only one of the listed resins .
