20160217443 "Digital rights management system providing trial use and facilitating purchase of managed documents," assigned to Konica Minolta Laboratory U.S.A., Inc.
A digital rights management method provides effective enforcement of purchase requirements to prevent users from accessing documents before purchasing the rights, and also provides the users with limited trial access to review the document before purchase. A digital rights management server maintains a database with information regarding users' payment status with respect to documents and their trial access status with respect to unpaid documents. Various trial modes may be implemented, including a "trial period" mode, a "number of attempts to open" mode, and a "summary view" mode. When a user attempts to access a document, the application on the client computer transmits a request to the server, and the server determines whether the user has paid for the document, or whether he should be given trial access, and transmits a reply to the client accordingly. The reply may include an invitation to pay for the document.
