Patent 7788290 was granted and assigned to Microsoft on August, 2010 by the United States Patent and Trademark Office.
A conversion tool that is automatically launched enables file formats not understood by a given application to be opened by that application. The converter registers for file types that are not already associated with an application used by the system. When a file that is not supported by another application is opened, the converter automatically converts the file to the target format and then opens the file causing the application that is registered for the target format to be launched.
