Abstract
Security services and policy enforcement for electronic data is provided through a series of transactions among a server and clients using electronic security certificates. A first client generates a digest from the electronic data, and submits a security certificate request containing the digest to a trusted arbitrator server, where the request is time stamped and logged. The trusted arbitrator authenticates the first client's credentials and returns the security certificate to the first client. The data and security certificate are combined to create a distribution unit. A second client acquires the distribution unit, extracts the security certificate, and generates a digest from the data. If the digest from the second client matches the logged digest from the first client, the data is valid. Depending on the certificate type and policy level, the trusted arbitrator server provides other services to the clients, such as notification of improper user of the data.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
