| | Irdeto Access, Inc. v. Echostar Satellite Corporation, et al. |
 | | Irdeto Access, Inc. (“Irdeto”) appeals the decision of the United States District Court for the District of Colorado granting summary judgment of noninfringement to Echostar Satellite Corporation, and Kudelski, S.A. and Nagravision, S.A. (collectively, “Echostar”). |
 | | Irdeto brought suit against Echostar on June 12, 1998, alleging that the DISH Network system infringed the ’020 patent as well as U.S. Patent No. 4,531,021; the latter is not at issue in this appeal. |
 | | Irdeto attempts to explain away this passage by arguing that because a group may be a subset as small as one subscriber, in that particular instance, the group key/group address and box key/box address pairs overlap. |
