Application 08/826,618
Claim 20 is reproduced below.
20. A data processor controlled display system for
displaying a virtual three-dimensional workspace comprising:
means for displaying a plurality of virtual three-
dimensional objects in said virtual workspace;
means for storing for each of said virtual objects, at
least one planar two-dimensional image of said virtual
object;
user interactive means for selecting one of said
virtual objects;
means responsive to said selecting means for displaying
the two-dimensional image of said selected object;
user interface means for navigating away from said
selected virtual object within said three-dimensional
workspace, and
means for user interactive input to said displayed
two-dimensional image, said input means remaining
interactive after the user has navigated away from said
selected virtual object.
The Examiner relies on the following prior art references:
Linnett et al. (Linnett) 5,682,469 October 28, 1997
(filed July 8, 1994)
Lynch et al. (Lynch) 5,689,669 November 18, 1997
(filed April 29, 1994)
Claims 20-22 stand rejected under 35 U.S.C. § 103(a) as
being unpatentable over Linnett and Lynch. The Examiner finds
that Linnett teaches the claimed invention except for the
two-dimensional image corresponding to the three-dimensional
object being an "image of said virtual object." The Examiner
