Patents in India: An Overview for Foreign Businesses
A patent in India is an exclusive right granted for a new, inventive, industrially applicable invention. It is administered by the Indian Patent Office under the Controller General (CGPDTM), governed by the Patents Act 1970. India has no utility-model right and examination happens only on request. A granted patent generally runs for a term measured from the filing date (commonly stated as twenty years under current law), subject to renewals; confirm the current term and schedule with the Indian Patent Office.
Patents in India matter to any foreign business that manufactures, licenses, or sells technology into one of the world's larger markets, and the system has enough distinctive features that an overview is worth having before you commit to a filing strategy. A patent is an exclusive right granted for an invention, a product or process that is new, involves an inventive step, and is capable of industrial application. In India, patents are governed by the Patents Act 1970 and the Patents Rules, and they are administered by the Indian Patent Office under the Controller General of Patents, Designs and Trade Marks (the CGPDTM). This page frames how the system works at a high level and points to a detailed walkthrough for the mechanics. It is general information, not legal advice. For anything fact-specific, the sensible course is to consult a vetted local firm.
What a patent protects in India
A granted patent gives its owner the exclusive right to prevent others from making, using, selling, or importing the patented invention in India without consent, for the life of the patent. Protection is tied to what the granted claims actually cover, so the drafting of those claims, not the broad description of the technology, defines the boundary of the right. A patent is a territorial right: an Indian patent is enforceable in India and does not by itself confer protection elsewhere.
Two features of the Indian system shape what protection means in practice. First, India has no utility-model or petty-patent right. There is no second tier of shorter, lightly examined protection for incremental inventions, so an invention either qualifies for a full patent or it does not, which makes the inventive-step threshold consequential. Second, the Patents Act sets out specific categories of subject matter that are not patentable in India, and these exclusions are applied more firmly in some areas than applicants from other jurisdictions expect. Both points are worth pressure-testing with local counsel before filing.
Who administers patents: the Indian Patent Office under the CGPDTM
Patents in India are handled by the Indian Patent Office, which operates under the Controller General of Patents, Designs and Trade Marks. The office examines applications, raises objections, grants patents, and maintains the register, all under the Patents Act 1970 and its rules. India has several patent office branches with defined territorial jurisdiction. The appropriate branch is fixed by territorial-jurisdiction rules (broadly tied to the applicant's place of business or, for foreign applicants, the agent's address for service), so the correct one depends on your circumstances; your agent will confirm it.
In practice most foreign businesses act through a registered Indian patent agent and must provide an address for service in India. Official proceedings are conducted accordingly. This representation is a structural feature of how foreign filers deal with the office rather than an optional extra, so it is worth factoring agent engagement into your planning from the outset. Confirm the exact representation and address-for-service requirements for your situation with local counsel, since those rules sit in the detail and can change.
The broad shape of getting a patent
Mechanically, obtaining an Indian patent follows a recognisable arc, with one feature that catches out applicants used to systems where examination is automatic. You file an application (often a complete specification, sometimes preceded by a provisional), the application is published after a set period, and the office then examines it, but examination does not begin automatically. In India, examination happens only on request: an applicant must file a request for examination within a prescribed period, and if that request is not filed in time the application is generally treated as withdrawn by the applicant. The length of that period has been revised over the years, including a recent reduction, so do not rely on a figure you have seen elsewhere; confirm the current request-for-examination deadline with the Indian Patent Office or your agent. Once examination is requested, the office issues its objections in an examination report, the applicant responds and amends as needed, and if the objections are resolved the patent is granted.
Timelines vary with the office's workload and with whether any expedited route applies, and the relevant periods have shifted over the years, so treat any single figure as indicative only. Build margin into any commercial plan rather than relying on a best case, and confirm current publication periods, examination-request deadlines, and processing times via the Indian Patent Office's official channels or your agent. The full procedure, including provisional and complete specifications, the examination-request deadline, and response timelines, is covered in the how-to guide.
How long protection lasts
Under the Patents Act 1970 the term of a patent is generally measured as twenty years from the date of filing of the application (for applications entering the Indian national phase under the PCT, that filing date is generally the international filing date rather than the later national-phase entry date), subject to keeping the patent in force. Maintaining a granted Indian patent requires paying renewal (annuity) fees on the prescribed schedule, and a patent can lapse if renewals are missed, though there is provision for restoration within a limited period in defined circumstances. The exact term, renewal schedule, restoration window, and fees are version-specific, so confirm the current term, start date, renewal timetable, and any restoration provisions directly with the Indian Patent Office or through your agent rather than relying on a fixed figure.
Disclosure obligations: a point foreign applicants must get right
India places disclosure duties on applicants that go beyond what some other systems require, and they are a recurring source of difficulty for foreign filers. Two in particular deserve flagging at overview level.
Under Section 8 of the Patents Act, an applicant who is also pursuing corresponding applications for the same or substantially the same invention outside India must keep the office informed about those foreign applications, and must supply prescribed information about them, including, on the Controller's requirement, details of their processing. This is an ongoing duty during prosecution, not a one-off form at filing, and failure to comply can be raised against the patent. The periods for furnishing Section 8 information are set by the rules and have been revised, so track corresponding foreign filings deliberately and respond to the office's requirements within the periods prescribed by the current rules.
The Act also requires disclosure relating to the source and geographical origin of biological material used in an invention, where relevant. Where an invention draws on biological material, additional disclosure and, in some cases, regulatory approvals can apply. If your technology touches biological material, raise it with local counsel early.
Foreign-filing licence: inventions originating in India
A separate point catches out multinationals with research or inventors in India. Under Section 39 of the Patents Act, an invention made in India, or made by a person resident in India, may require either a first Indian filing or the Controller's written permission (commonly called a foreign-filing licence) before any application for it is filed abroad. Where the route is a first Indian filing rather than a licence, a prescribed waiting period after that Indian filing may also apply before an overseas filing can proceed, so a same-day foreign filing does not necessarily clear the bar. Non-compliance carries consequences under the Act. If any of your inventors are based in India or the invention was made there, treat the foreign-filing question as a gating item and confirm the current Section 39 conditions, timing, and process with local counsel before filing anywhere.
The route in: direct national filing or the PCT
Foreign businesses generally reach India either by a direct national filing through an Indian patent agent or by entering the Indian national phase from an international application under the Patent Cooperation Treaty (PCT), the WIPO-administered system for seeking patent protection in multiple countries through one international application. A direct national filing can suit a single-country need or a fast first filing; a PCT route suits a multi-country programme, deferring the country-by-country commitment while preserving an early priority date. Either way, the Indian national-phase or national filing still goes through the Indian Patent Office and is subject to the same examination, disclosure, and renewal rules described above. For the wider mechanics of the international route, see our overview of the PCT.
Main practical considerations for a foreign business
Several recurring issues are worth holding in view. The examination-on-request rule means a deadline can pass quietly and cost you the application, so it should be diaried from the day you file or enter the national phase, with the current period confirmed rather than assumed. The disclosure duties, Section 8 in particular, demand active management of your corresponding foreign portfolio rather than a single declaration. The foreign-filing-licence question is a genuine gate for anything invented in India and is easiest to handle before, not after, an overseas filing. And because India has no utility-model fallback, the inventive-step threshold and the subject-matter exclusions carry more weight than in jurisdictions where a lesser right is available.

Because the consequences of each of these points are jurisdiction-specific and often turn on facts, the sensible course before filing in India is to consult a vetted local firm to pressure-test your subject matter, your claims, your disclosure compliance, and your filing route.
