Patent Filing India for Foreign Applicants

Patent filing, PCT national phase and enforcement in India for foreign applicants.

Strategic context

The issues that decide the outcome

A foreign company protecting an invention in India usually enters through the PCT national phase or a Paris Convention route, and the India-specific provisions can materially affect what is patentable and how the application fares. Section 3 excludes certain subject matter, including specified software and business-method claims and some pharmaceutical forms under the Section 3(d) efficacy test, so claims drafted for other jurisdictions often need adaptation for India. The foreign-filing and information-disclosure requirements also impose obligations that applicants miss.

Beyond grant, India imposes a working requirement with a periodic statement on the commercial working of the patent, and the pre-grant and post-grant opposition routes give third parties real opportunities to challenge. We manage the national-phase entry and prosecution, adapt claims to the Indian patentability rules, handle the statutory disclosures and working statements, and defend or bring oppositions so the patent is granted and remains enforceable.

Answers

Frequently asked questions

01How does a foreign company get a patent in India?

Most commonly through the PCT national phase, entered within the prescribed deadline, or through a Paris Convention application claiming priority from a home filing. The claims should be reviewed and adapted to the Indian patentability rules on entry.

02What is not patentable in India?

Section 3 excludes certain subject matter, including specified software per se and business methods, and the Section 3(d) test limits patents on new forms of known pharmaceutical substances without enhanced efficacy. Claims drafted for other jurisdictions often need adaptation for India.

03What is the patent working requirement?

India requires the patentee to file a periodic statement on the extent to which the patent is being commercially worked in India. This is a continuing obligation after grant, and non-compliance can have consequences, so it should be tracked.

04Does an initial discussion create a lawyer-client relationship?

No. No engagement is treated as accepted until conflicts, scope and terms are confirmed in writing. An initial discussion is confidential and is used only to understand the matter and assess fit.
