Microsoft’s Operating System Sued for Patent Infringement
On Friday in the Western District of Texas, plaintiff Panther Innovations, LLC filed a complaint against Microsoft Corporation, claiming that Microsoft infringed the patents-in-suit through its operating systems that allegedly utilize network speed optimization.
The patents-in-suit are United States Patent Nos. 7,840,652 (the ’652 patent) and 8,069,231 (the ’231 patent), both relate to optimizing network and internet data transfer speeds. The plaintiff explained that “the Asserted Patents describe certain TCP/IP settings that can be adjusted to optimize the network connection, including, for example, Maximum Transmission Unit (MTU), Maximum Segment Size (MSS), Receive Window (RWIN), Time to Live (TTL), Black Hole Detection, and MTU Auto Discovery.”
According to the complaint, Microsoft has infringed the patents-in-suit “by making, using, offering to sell, and selling within the United States…certain products and services,” that purportedly infringe these asserted patents. The plaintiff stated that Microsoft’s accused products have “various user-selectable network configuration settings,” including “Windows Vista, Windows 7, Windows 8, and Windows 10 operating systems.”
