ThroughPuter, Inc. v. Microsoft Corporation DC

In late March, Eastern District of Virginia Judge M. Hanna Lauck granted a Microsoft motion to transfer the case filed by ThroughPuter, Inc. there, a year ago nearly to the day, to the Western District of Washington. After losing the six-months long fight over that proposed transfer, ThroughPuter has doubled down, filing a new case against Microsoft (2:22-cv-00492) in the Western District of Washington, asserting two more patents from the same large family, both having issued to the plaintiff since it filed the first case last year. Both cases are situated in a central dispute over the early development of modern distributed computing systems.

Inventor-controlled ThroughPuter, Inc. has sued Microsoft (3:21-cv-00216) over the provision of its Azure cloud computing platform. The nine asserted patents, from the same family of nearly three dozen, are generally related to various aspects of parallel processing in a network of shared computing resources, the most recent of which issued on March 30, 2021. The new complaint alleges a history of interactions between the parties that preceded the current litigation.
