Appeal No. 2004-0870 Page 5 Application No. 09/477,419 1. Claim Construction "Analysis begins with a key legal question — what is the invention claimed?" Panduit Corp. v. Dennison Mfg.

In re Lowry, 32 F.3d 1579, 1582, 32 USPQ2d 1021, 1034 (Fed. Cir. 1994) (citing In re Gulack, 703 F.2d 1381, 1385, 217 USPQ 401, 403-04 (Fed. Cir. 1983)). Here, claim 1 recites in pertinent part the following limitations: "a user-selectable mode of operation in which only an active one of the multiple task windows is normally displayed at a time, and a minimized representation is provided for all non-active task windows." Claim 30 includes similar limitations. Considering these limitations, claims 1 and 30 require that a user can select and de-select a mode that displays an active task window and a minimized representation of all non-active task windows. 2.
