Abstract
A subscribing user generates a private key and a corresponding public key stored locally in a 'key-ring.' The public key is uploaded to a key repository on a communications server, where public keys of subscribers are maintained. When sending a secure message, the sender's key-ring is checked to determine whether the public key for the recipient is present. If yes, then the public key is used to encrypt the message. If no, then a lookup request is sent to the server to determine whether a public key is available for the recipient. If there is, then the public key is downloaded from the repository to the sender. When the recipient receives the secure message, the recipient's private key is used to decrypt the message. The sender's most recent public key also is transmitted with the message and stored in the recipient's key-ring for future messages sent back to the key owner. Automated key management features are included.

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.
