Abstract
Multiple different credentials and/or signatures based on different credentials may be included in a header portion of a single electronic message. Different recipients of intermediary computing systems may use the different credentials/signatures to identify the signer. The electronic message may include an encoding algorithm and a type identification of a credential included in the electronic message, allowing the recipient to decode and process the credential as appropriate given the type of credential. Also, the electronic message may include a pointer that references a credential associated with a signature included in the electronic message. That referenced credential may be accessed from the same electronic message, or from some other location. The recipient may then compare the references credential from the credentials used to generate the signature. If a match occurs, the integrity of the electronic message has more likely been preserved.

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.
