Question:Does your USPTO database include data on the current fee status and expiration of patents?

Question:How do I obtain the status of a patent?

Answer:
The Patent Application Information Retrieval (PAIR) system permits third parties to obtain information about applications that have been published pursuant to 35 U.S.C. 122(b) and issued patents, such as the status of maintenance fee payments and whether or not a reissue application or reexamination request has been filed. PAIR can be accessed on the United States Patent and Trademark Office (USPTO) web site at http://portal.uspto.gov/external/portal/pair.
