File history of an IP asset refers to the legal record of communications between the patent office and the applicant/representative that had occurred during the prosecution of the application prior to issuance or rejection of the IP right. It contains statements made by the applicant and record of interviews between the applicant and the patent office.

Concerning patents, file history reports reflect the evolution of patent claims during prosecution and can be insightful for litigation purposes, due diligence, licensing, business transactions, etc. File history analysis fishes out relevant prior art references cited by the examiner and is useful for infringement proceedings. A clear idea of the scope of the claims is obtained during the analysis.
