Quick answer
A patent can protect a qualifying invention in India if it is new, involves an inventive step and is industrially applicable, subject to statutory exclusions. Start with confidentiality and a patentability assessment, then file an appropriate specification with the Patent Office. Publication and a separate examination request precede substantive examination and possible grant.

Overview
What you need to know about Patent Registration & Filing in India
The Patents Act, 1970 governs Indian patents. An invention must meet novelty, inventive-step and industrial-applicability requirements and avoid statutory exclusions, including those in Sections 3 and 4.
Form 1 is the application and Form 2 contains the provisional or complete specification. A provisional filing must be followed by a complete specification within 12 months; it is not itself a granted patent.
Examination is requested using Form 18, or Form 18A where expedited-examination eligibility is met. The usual patent term is 20 years from filing, subject to renewal fees; for a PCT national-phase patent, it runs from the international filing date.
Is this for you?
Who needs this and when
Inventors and businesses developing technical products or processes should assess patent protection before public demonstrations, sales, academic publication or online disclosure. India does not offer a broad general grace period that safely cures every earlier disclosure. A patent search helps identify relevant prior art, but cannot guarantee grant or complete visibility of unpublished applications. Establish who invented the subject matter and who owns the right to apply, especially where employees, consultants, university researchers or collaborators contributed to the work.
Not every useful idea is patentable. Business methods, computer programs per se, methods of medical treatment and other excluded subject matter require careful legal analysis under the Patents Act. Software-related inventions should be assessed on their actual technical substance rather than a label. A provisional specification may secure a filing date for sufficiently disclosed subject matter, but is not a granted patent. Businesses also need a separate freedom-to-operate review before commercialisation, because patentability does not establish permission to use another party technology.

Timeline
How long it takes
Invention disclosure and prior-art assessment
Usually 1–3 weeks
Specification drafting and inventor review
Usually 2–6 weeks, depending on complexity
Complete specification after provisional filing
Within 12 months where a provisional route is used
Ordinary publication
Generally after 18 months from filing or priority; early publication is available
Examination, objections and grant consideration
Often several years overall; expedited routes depend on eligibility
Avoid delays
Common mistakes to avoid
- Publishing or pitching technical details without confidentiality safeguards can destroy novelty, so patent strategy should be considered before demonstrations, papers, crowdfunding or unrestricted customer discussions.
- Treating a provisional specification as a placeholder with minimal technical detail risks weak priority support and does not excuse filing a complete specification within twelve months.
- Assuming filing automatically starts substantive examination overlooks the separate examination request and its deadline, which depends on the application filing date and applicable transitional rules.
- Confusing a patentability search with freedom to operate can leave a business exposed to earlier patents even when its own improvement is independently patentable.
- Naming only the founder while excluding actual inventors or ignoring assignment documents can create ownership disputes during examination, licensing, investment diligence or enforcement proceedings.
Next steps
After it’s done: staying compliant
Keep laboratory records, drawings, inventor approvals and assignment documents securely organised. For applications filed on or after 15 March 2024, the ordinary examination-request deadline is generally 31 months from the priority or filing date, whichever is earlier; earlier applications have transitional treatment. Confirm the deadline for the particular application rather than relying on a generic reminder. Respond to examination reports and comply with foreign-application disclosure obligations where applicable, using a qualified patent professional for substantive prosecution.
After grant, track renewal fees, ownership records and any licence terms. The ordinary patent term is twenty years from filing, with the relevant international filing date applying to PCT national-phase cases. Working statements under Form 27 follow the current three-financial-year reporting framework, subject to applicable rules and extensions. Review commercialisation separately from grant, including regulatory approvals and third-party rights. An Indian filing does not itself provide worldwide protection, and overseas protection requires timely strategic decisions.
FAQs
Frequently asked questions
Does the starting price include a complete patent?
No. It is an indicative entry-level professional fee, not an all-inclusive grant price. Search, technical drafting, official fees, prosecution, hearings and overseas filings require a scope-specific quotation.
Can software or a business idea be patented?
An idea alone is insufficient. Business methods, algorithms and computer programs per se are excluded under Section 3(k); a technical invention requires careful assessment under applicable law and examination guidance.
How long does a patent take?
Initial drafting may take 2–4 weeks after a complete disclosure. Examination and grant can take substantially longer, often years; expedited examination is available only to eligible applicants.
What deadlines can put the application at risk?
A complete specification is due within 12 months of a provisional filing. For applications filed on or after 15 March 2024, examination is generally requested within 31 months from priority or filing, whichever is earlier; earlier applications generally retain the 48-month period.
What must I do after grant?
Pay renewal fees and meet applicable working-statement and other obligations. Form 27 is generally required for each three-financial-year period under the amended rules. An Indian patent does not protect the invention overseas.
Should I disclose the invention before filing?
Avoid public disclosure until filing strategy is settled. India does not offer a general grace period for all inventor disclosures, and publication or sale can destroy novelty unless a specific exception applies.
Key takeaways
- Protect confidentiality before disclosing potentially patentable technical details.
- A provisional filing is neither a granted patent nor an unlimited extension.
- Substantive examination requires a separate timely request.
- Patentability and freedom to operate answer different business questions.
- Renewals, reporting and territorial limits remain important after grant.
