Microsoft has filed a patent for a technology that would enable multiple users to wirelessly connect to a single computing device and share a desktop session.
The idea is based on a centralized screen sharing scenario, in which users are not accessing a screen of another user, but leverage a dedicated computing device with the purpose of serving as a collaboration platform. The patent is set up to describe a service that could, conceivably, be offered as a commercial cloud product, especially since it also mentions the possibility of a session administrator. Shared "resources" would, for example, include collaborative editing of a text document or a presentation.
What makes this patent filing interesting is the fact that Microsoft offers a similar feature for Office 365 as it enables co-authoring of documents via a SharePoint server.
However, Google, for instance, has been offering a similar service for Docs and any other centralized collaboration feature is sure to collide with this patent. Microsoft may have a tough time enforcing the patent, if it is granted, in its general form. This specific document focuses on wireless connections, but we have doubt that this claim will be unique enough to grant Microsoft to the rights to the universal form of enabling centralized screen and resource sharing.
