Magistrate Judge Burke Construes Terms of Patents Asserted Against Microsoft Kinect

Magistrate Judge Burke recently issued a thorough report and recommendation on claim construction in a patent infringement dispute between plaintiff Impulse Technology and defendants, Microsoft and the makers of several games for Microsoft’s Xbox 360 system and Kinect sensor. See Impulse Tech. Ltd. v. Microsoft Corp., C.A. No. 11-586-RGA-CJB, Report and Recommendation at 1-4 (D. Del. May 13, 2013). In addition to the parties’ agreed-upon constructions, Judge Burke construed the following disputed terms related to tracking the position of a player in physical and virtual spaces:

- “a tracking system”
- “defined physical space” and “first/second physical space”
- “virtual space”
- “player virtual location[s] in a virtual space corresponding to the physical location[s] of the player[s]”
- “positioning the representation of the user on the monitor” and “moving the representation of the user to reflect movement of the user”
- “representation”
- “overall physical location”
- “moving in the physical space”
- “[the view is from a] point of view in the virtual space corresponding to a location on a line directed outward from the display into the physical space”

Id. at 61-62.

UPDATE:
In a recent Order, Judge Richard G. Andrews adopted Judge Burke's recommended constructions, but provided additional clarification as to the proper construction of the following terms: "overall physical location" and "'positioning the representation of the user' and 'moving the representation of the user to reflect movement of the user.'" Impulse Technology Ltd. v. Microsoft Corporation, et al., C.A. No. 11-586-RGA-CJB (D. Del. Sept. 19, 2013).
