Microsoft and I-O Data Device Inc entered into an agreement to provide I-O Data’s customers with patent coverage for their use of I-O Data’s products running Linux and other related open source software. Specifically, patent covenants apply to I-O Data’s network-attached storage devices and its routers, which run Linux. Although details of the agreement have not been disclosed, parties indicated that Microsoft is being compensated by I-O Data. This patent agreement is an extension of the strong relationship between Microsoft and I-O Data in both the consumer and enterprise markets. The companies recently worked together on a Windows 7 marketing campaign, and I-O Data released one of the industry’s first Windows 7 API-based sensors, which automatically detects when a person enters or leaves an office or room.
