Text: ating system that in turn utilizes subsystems from at least one other operating system, comprising: receiving documents from diverse applications in formats that are specific to the respective ap- plications and differ as between at least some of said applications; automatically associating time-based indicators with the documents received in the receiving step from the diverse applications; automatically archiving the received documents; automatically creating glance views that are ab- breviated versions of respective ones of said documents; selectively displaying at least some of said documents as a receding, foreshortened stack of partly overlapping documents so that only a part of each of said documents in the displayed MIRROR WORLDS v. APPLE 6 stack, after the first document in the stack, is visible to the user; said displaying further including displaying a cursor or pointer and responding to a user sliding the cursor or pointer over said displayed stack to display the glance view of the document in the stack that is currently touched by the cur- sor or pointer, without requiring clicking on the document; and utilizing, in said document stream operating system, subsystems from said at least one other operating system for operations including writing documents to storage media, interrupt handling and input/output. ’313 patent col. 16 ll. 14–26. The asserted claims of the ’227 patent (independent claim 13 and dependent claim 22) do not contain the “cursor or pointer” limitation. Claim 13 recites a method for organizing documents as they are generated in and received by the computer: 13. A method which organizes each data unit re- ceived by or generated by a computer system, comprising the steps of: generating a main stream of data units and at least one substream, the main stream for re- ceiving each data unit received by or gener- ated by the computer system, and each substream for containing data units only from the main stream; receiving data units from other computer systems; generating data units in the computer system; selecting a timestamp to identify each data unit; 7 MIRROR WORLDS v. APPLE associating each data unit with at least one chronological indicator having the respective timestamp; including each data unit according to the time- stamp in the respective chronological indicator in at least the main stream; and maintaining at least the main stream and the substreams as persistent streams. ’227 patent col. 16 ll. 9–25. Claim 22, which depends from claim 13, recites an additional limitation for “archiving data units having timestamps older than a specified time point.” Id. col. 16 ll. 61–64.
