A method and a system for setting a priority level of a call in which a request is received for changing a priority level of a call to one of a plurality of available call priority levels, the priority level of the call is changed based on the received request, and the call is handled based on the changed priority level of the call. The request for changing the priority level of the call can be a request for a central office service feature for changing the priority of the call, receipt a call routed to a predetermined telephone number, such as an 800, an 888, a 900 or a charge-to-caller number, or receipt of a DTMF signal indicating the requested priority level. A message can be generated providing a menu for changing the priority level of the call having at least one available priority level with an associated charge rate for each available priority level. When the priority level of the call is changed, the call can be advanced in a call holding queue, a lower priority call can be interrupted or the call can be routed on a high-priority trunk capacity available for high-priority calls.
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.
