A communication system for transmitting address changes. A communication system includes a source communication system and one or more destination communication systems, each of which is identified by a unique number or address. A memory in the source communication system maintains a record of each destination communication system that communicates with it. If the number or address of the source communication is changed, the source communication system generates a new number or address message which is transmitted to each of the destination communication systems. The destination communication systems receive the new number or address message and update a memory to reflect the new number or address of the source communication system. Those destination systems that are able to read the new number or address message and update a record of the number or address for the source communication system generate an acknowledge signal which is transmitted to the source communication system. The source communication system may transmit a human readable new number or address message to those destination communication systems that have not transmitted the acknowledge signal. The communications systems may comprise telephones, facsimile machines or computers having e-mail or IP addresses.

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.
