Overall Summary Table

*The ‘Maibox’ system allowed India to defer the granting of product patents for Agrochemicals and Pharmaceuticals until amendments to the Patent Act of 1970 came into force in 2005. Prior to accession to the WTO, the Patent Act of 1970 in India  provided protection of processes and methods of manufacture of Agrochemicals and Pharmaceuticals, but not for the products themselves. In compliance with the Trade-Related Intellectual Property Rights (TRIPS) on 1st January 1995, India  set up the ‘Mailbox’ system for filing patent applications for these products.

** 2 letters are used to identify the regional office and national/PCT filing routes in the standard Derwent Application Number format, due to legacy system constraints. For customers taking a direct XML datafeed, these are converted back to the corresponding full 3 letter regional office codes (DEL, KOL, CHE, MUM) plus the 2 letter PCT Transfer signifier "NP" where appropriate (DELNP, KOLNP, CHENP, MUMNP).
