Regents of the Univ. of MN v. AGA Med.Corp.

The University of Minnesota owns the 281 and 291 patents, which are directed to “septal occluders,” medical devices for repairing holes in the septum of the heart, using a catheter threaded through a vein. The University accused AGA of infringing both patents. AGA’s accused septal occluders are one-piece devices made from tubes of wire mesh. After claim construction, the district court granted summary judgment that the 291 patent was not infringed and that the asserted claims of the 281 patent were invalid as anticipated. The Federal Circuit affirmed. The district court properly construed the terms “affixed” and “conjoint” to conclude that the 291 patent requires two physically separate disks.
