Microsoft Assigned Patent

Microsoft Corp., Redmond, WA, has been assigned a patent (8,725,782) developed by five co-inventors for “virtual disk storage techniques.“

The co-inventors are Dustin L. Green, Redmond, Mathew John, Redmond, WA, Todd William Harris, Sammamish, WA, John A. Starks and Senthil Rajaram, Seattle, WA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ” This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.“

The patent application was filed on April 25, 2011 (13/093,731).
