Why Businesses Choose Corpus Juris Legal
Patents protect technical innovations — new processes, products, and designs that provide a competitive advantage. India's patent law under the Patents Act 1970 has unique features that affect protection strategy: the Section 3(d) provision that restricts patents on incremental pharmaceutical innovations, the working requirements (Form 27 filings), and the compulsory licensing provisions. Corpus Juris Legal's patent practice covers Indian patent filing and prosecution, freedom-to-operate (FTO) analysis, patent licensing and assignment, and patent enforcement and invalidation proceedings.

Frequently Asked Questions
What can be patented under Indian patent law?+
An invention that is new, involves an inventive step, and is capable of industrial application can be patented. However, Section 3 of the Patents Act excludes several categories: abstract ideas, mathematical methods, computer programs per se, business methods, and discoveries of natural phenomena. Software patents are possible in India if claimed as a technical process producing a technical effect.
How long does patent prosecution take in India?+
Filing a patent application establishes the priority date immediately. The application is published 18 months after filing. Examination begins only after a Request for Examination (RFE) is filed (within 48 months of priority date). First examination report typically issues within 12-24 months of RFE. Total prosecution from filing to grant: 3-5 years on average.
Is an Indian patent valid globally?+
No — patents are territorial. An Indian patent gives protection only in India. For global protection, you must file in each country where protection is needed, typically using the Patent Cooperation Treaty (PCT) within 12 months of the Indian priority filing. We advise on international patent strategy alongside Indian prosecution.
