Abstract
In a system and method and system for controlling delivery of unsolicited electronic mail messages, one or more spam probe e-mail addresses are created and planted at various sites on the communications network in order to insure their inclusion on large-scale electronic junk mail ('spam') mailing lists. The mailboxes corresponding to the spam probe e-mail addresses are monitored for incoming mail by a spam control center. Upon receipt of incoming mail addressed to the spam probe addresses, the spam control center automatically analyzes the received spam e-mail to identify the source of the message, extracts the spam source data from the message, and generates an alert signal containing the spam source data. This alert signal is broadcast to all network servers and/or all user terminals within the communications network. A filtering system implemented at the servers and/or user terminals receives the alert signal, updates stored filtering data using the spam source data retrieved from the alert signal, and controls delivery of subsequently-received e-mail messages received from the identified spam source. The filtering system controls delivery of the unsolicited e-mail messages by discarding the messages without displaying them to the user, displaying the messages to the user with a 'JUNK' or similar marker, or otherwise processing the spam mail as desired by the network provider and/or the network users. The filtering system may also filter e-mail messages sent by the user terminals.

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.
