India

India had a patent office ("The Patent Office") located at 1, Council House Street, Calcutta. Local and internationals could and did apply for Indian patents.

India had a special own patent law including a unique patent law governing Mysore. Indian patents were effective from the date on which the complete specification was filed. Their normal duration was fourteen years, or until the expiration of the identical patent in GB or another foreign country, whichever came sooner. Average cost, £18.

An initial survey of some of the available patents from 1912 suggests that, while a few prolific international filers submitted patents in India, the overall trend of patents was towards the agricultural and industrial processes corresponding to the Indian economy at the time. (For example, patents for tea, sugar, and food production processes, as well as for general infrastructure and communications, especially railway and telegraph.)

IN is an abbreviation in this wiki referring to India.

We have used INPASS to gather some of our information on Indian patents in this time period.
