Where can Prosecution History be found

Prosecution history is available to the public in the USPTO’s Patent Application Information Retrieval system (PAIR) http://portal.uspto.gov/pair/PublicPair PAIR accesses patent information held in the USPTO internal Patent Application Locating and Monitoring (PALM) system and presents it in two different web-based views: Public PAIR and Private PAIR. PAIR provides web-based access for pending patent information and eases the process of tracking patents, patent applications, and follow-on documents through the USPTO approval process. Public PAIR provides status and history information for issued patents and published applications. In Public pair you can search for application information using the Application number; the control number; a Patent number; a PCT number; or the publication number. Private PAIR provides controlled access to non-public patent information, and Private PAIR provides access to all public information.  There is an application process to gain access to Private PAIR.
