Abstract
A hybrid encryption method for securely transferring an electronic data package from a sender to a plurality of clients. The method comprises storing a shared symmetric key on each of the clients. The sender encrypts a private key of an asymmetric key pair using the shared symmetric key. The sender encrypts the data package with a temporary symmetric key to generate an encrypted data package. The sender encrypts the temporary symmetric key with the public key of the asymmetric key pair to generate an encrypted temporary symmetric key. The sender transmits the encrypted data package, the encrypted temporary symmetric key, and the encrypted private key to the clients. Each client decrypts the encrypted data package by: using the shared symmetric key to decrypt the encrypted private key; using the decrypted private key to decrypt the encrypted temporary symmetric key, and using the decrypted temporary symmetric key to decrypt the encrypted data package.

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.
