The official filing languages in India are English and Hindi. If you are filing a patent application with the IPO, you can file the application in either of the two languages. However, in the case of Patent Cooperation Treaty (PCT), you can file the application in English or any language that ISA accepts. However, even if the ISA accepts the filing, the language may not be fit for publication. Hence, if your language is different than the publication language, you must submit a translation of the application. These languages are Arabic, Chinese, English, French, German, Japanese, Korean, Portuguese, Russian or Spanish.
As far as the official filing languages in India go, Hindi and English will work.
