Baldwin Graphics Sys., Inc. v. Siebert, Inc.
January 22, 2008
Baldwin Graphic Systems, Inc. (Baldwin) sued Siebert, Inc. (Siebert) for infringement of U.S. Patent No. Re. 35,976 (the Reissue patent) and U.S. Patent No. 5,974,976 (the ’976 patent). After conducting a Markman hearing, the United States District Court for the Northern District of Illinois ultimately granted Siebert’s motions for summary judgment of non-infringement of both patents. Because the district court erred in its construction of some of the disputed claim terms, this court affirms-in-part, reverses-in-part, and remands.
