Abstract
The invention provides techniques for implementing secure transactions using an instrument referred to as 'executable digital cash.' In an illustrative embodiment, a first user generates a piece of digital cash representing an offer made by that user. The piece of digital cash includes a digital certificate authorizing the first user to make specified transfers, and an offer program characterizing the offer. The piece of digital cash is broadcast or otherwise transmitted to one or more additional users, utilizing a mobile agent or other suitable mechanism, such that a given one of these users can evaluate the offer using the offer program. For example, a second user could execute the offer program with a specific bid as an input to determine what that user would receive upon acceptance of his bid. If the result is acceptable to the second user, that user generates a bid capsule including the bid, the corresponding output of the offer program, and another certificate authorizing the second user to make the transfer specified in the bid. The bid capsule is submitted to an institution for processing in accordance with a policy which may be specified in the piece of digital cash. The institution selects one or more winning bids and implements the corresponding transactions. Digital signatures generated using secret keys associated with the certificates of the first and second users are utilized to ensure adequate security for the transmitted offer and bid information.

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.
