INPASS New Indian Patent Advanced Search System.

The present system, IPAIRS, allows a search to be conducted in all the Indian Patents and Patent Applications. This system however does not allow a user to perform a full-text search. The Patent Office has developed a new search tool, INPASS,which allows a full-text search to be conducted in all the Indian Patents as well as Patent Applications. INPASS supports wild-cards, truncation as well as Boolean operators in all the fields of the ST.36 compliant data available with the Patent Office, thereby enabling the stakeholders to conduct an advanced search in the Indian Patent Database. IPAIRSwill henceforth be withdrawn.
Comments for further improving INPASS may be sent to cgoffice-mh@nic.in
