Abstract: A method and apparatus for collating, correlating and redistributing information about the use of proprietary products including copyrighted works and licensed software products, at various computer sites. The system consolidates information (originally captured by other systems) by time period, such as day, week or month, about which proprietary products are installed at each computer site, as well as to what particulars of use are relevant. This may include the number of invocations of various software products, the number of logons, the number of concurrent users, as well as other usage metrics. The information is sorted by vendor or copyright owner, so that the information about all of the proprietary products licensed from a particular vendor can be periodically sent to that vendor, automatically, or in response to prompting by vendors or from within the central computer system.
