Heading: The Collateral Estoppel Effect of Intellicall

Text: 23 We must first consider whether, as NTI and United suggest, we are bound by Intellicall, Inc. v. Phonometrics, Inc., 952 F.2d 1384, 21 USPQ2d 1383 (Fed.Cir.1992), in which this court also construed claim 1 of the '463 patent. The issue in Intellicall was whether the limitation digital display meant only visual display or also encompassed machine readable information. See id. at 1387-88, 952 F.2d 1384, 21 USPQ2d at 1386-87. The district court held, and we agreed, that the limitation digital display does not include machine readable devices, or information given to a computer for later access. Id. at 1388, 952 F.2d 1384, 21 USPQ2d at 1387. Any construction of other limitations in claim 1, including any construction of those limitations at issue here, that we or the district court made in Intellicall was merely dictum, and therefore has no issue preclusive effect for this appeal. 24
