1Opinion of the Court
MAYER, Circuit Judge.
Cat Tech LLC (“Cat Tech”) appeals the judgment of the United States District Court for the Southern District of Texas holding that none of four configurations of loading devices manufactured by Tube-Master, Inc. (“TubeMaster”) infringes U.S. Patent No. 6,905,660 (the “'660 patent”). We conclude that the district court correctly construed the “spacing” element of claims 3-7 of the '660 patent and that the dispute was sufficiently real and immediate to warrant a declaratory judgment of non-infringement. We therefore affirm.
