Upon dialing either of the above telephone numbers, you will first reach an automated information system. Often, the information sought can be obtained without speaking to an IAC representative. If you do not find the necessary information using the automated information system, your call will be forwarded to a USPTO Contact Center (UCC) operator. The UCC operator will provide answers to basic, non-technical questions and transfer calls to the IAC as necessary. So that we may assist all of our customers, we ask that you limit your calls to a reasonable length of time. A review of the materials available by mail or on the USPTO Web Site prior to your call will make your questions more meaningful and should provide the IAC staff with a better opportunity to properly answer your questions.
- The IAC will not be staffed during Government holidays . When the USPTO closes early (for example, due to weather conditions) the IAC will also cease operations.
- Operating Status for Washington DC Area
