IP Innovation L.L.C. and Technology Licensing Corporation (collectively, "Plaintiffs") have brought a patent-infringement action against Red Hat, Inc., and Novell, Inc., alleging infringement of U.S. Patent Numbers 5,072,412; 5,533,183; and 5,394,521. The patents concern a user interface that has multiple workspaces. The Plaintiffs' complaint identifies as accused products "Red Hat Linux system," the "Novell Suse Linux Enterprise Desktop," and the "Novell Suse Linux Enterprise Server."
UPDATE: THESE THREE PATENTS WERE INVALIDATED BY THE U.S. DISTRICT COURT, EASTERN DISTRICT OF TEXAS, ON APRIL 30, 2010, IN THE ABOVE REFERENCED ACTION.

Summary / Description
Summary / Description A key constraint on the effectiveness of window-based human-computer interfaces is that the display screen is too small for many applications. This results in “window thrashing,” in which the user must expend considerable effort to keep desired windows visible. Rooms is a window manager that overcomes small screen size by exploiting the statistics of window access, dividing the user's workspace into a suite of virtual workspaces with transitions among them. Mechanisms are described for solving the problems of navigation and simultaneous access to separated information that arise from multiple workspaces.

User interface with mulitple workspaces

A method of operating a system that includes: a display; a user input device for receiving signals from a user; and a data processor that receives input signals from the user input device and provides output signals to the display; the output signals causing the display to present images that include display objects; each of a set of the display objects being perceptible as a distinct, coherent set of display features; the method comprising: operating the data processor to provide first output signals to the display; the first output signals causing the display to present a first workspace containing a first subset of the set of display objects; the display objects of the first subset being perceptible as having spatial positions relative to each other when presented by the display; the first subset including a first display object that is perceptible as a tool that augments a user's capabilities; while the display is presenting the first workspace, receiving a switch signal sequence from the user input device; and in response to the switch signal sequence, operating the data processor to provide second output signals to the display; the second output signals causing the display to cease presenting the first workspace and begin to present a second workspace containing a second subset of the set of display objects; the display objects of the second subset being perceptible as having spatial positions relative to each other when presented by the display; the second subset including a second display object that is perceptible as a tool that augments a user's capabilities; the first and second subsets of display objects being different from each other so that the first and second workspaces are perceptible as different workspaces; the second display object being perceptible as the same tool as the first display object.
