The Search Workflow.

Four sequential stages over 2-4 weeks for a standard patentability search. Faster for narrowly scoped searches, longer for landscape analyses or freedom-to-operate studies. The deliverable is a written report and a clear recommendation: file as-is, amend the claims, redesign around prior art, or abandon.

Stage 1
Brief & scope
Invention disclosed under NDA. Technical features mapped. Search type selected: patentability search (novelty assessment), prior art search, freedom-to-operate (FTO), validity / invalidity, or landscape analysis. Jurisdictions decided (India only or with US / EP / WIPO). Section 3 exclusions screened upfront to avoid wasted search effort.
→
Stage 2
Database search & screening
Multi-database search executed. InPASS (Indian Patent Advanced Search System, official IPO database, free). Espacenet (European Patent Office, worldwide coverage). WIPO PATENTSCOPE (international PCT applications). USPTO and EPO where applicable. IPC classification + keyword + citation searches combined. Results filtered for relevance.
→
Stage 3
Analysis & opinion
Each relevant prior art reference analysed against your invention's claims. Patentability assessed on the three statutory criteria: novelty (Section 2(1)(l)), inventive step (Section 2(1)(ja), with the distinctively Indian "economic significance" lens), industrial applicability. Section 3 exclusions re-checked against the actual claim scope.
→
Stage 4
Report & recommendation
Written search report delivered: search strategy used, databases queried, relevant prior art with bibliographic references, patentability opinion, and a clear recommendation: file as-is, amend the claims to avoid identified prior art, redesign around a blocking patent, or abandon if patentability is unlikely. Report becomes the input for provisional filing strategy.
↺ One-time engagement per invention. Patent watch (ongoing monitoring of competitor filings in your technology domain) is a separate recurring engagement. Search precedes filing; search findings shape the provisional specification.

What Is a Patent Search?

A patent search is a pre-filing assessment of whether an invention is patentable under the Patents Act 1970 and the Patents Rules 2003. It is not a statutory requirement, an applicant may file without searching, but it is the single most cost-effective step in patent strategy. A well-conducted search costs a fraction of a patent application and prevents the largest avoidable expense in patent practice: filing, paying examination fees, and pursuing an application that will be refused because the invention is not new or not inventive in the eyes of the law.

Indian patent law tests every invention against three statutory criteria. Novelty under Section 2(1)(l): the invention must not have been anticipated by publication in any document or use anywhere in the world before the priority date. Inventive step under Section 2(1)(ja): the invention must involve a technical advance compared to existing knowledge, or have economic significance, the "economic significance" provision is distinctively Indian and allows patents where the innovation lies in cost reduction or resource efficiency rather than technical leap. Industrial applicability: the invention must be capable of being made or used in an industry. A patent search assesses each criterion against the actual claim scope.

Section 3 exclusions, the silent killer of Indian patent applications

Beyond the three positive criteria, Section 3 of the Patents Act excludes specific categories from patentability regardless of how novel or inventive they may be. Section 3(k): mathematical methods, business methods, and computer programs per se. Section 3(m): schemes for mental acts or playing games. Section 3(p): traditional knowledge. Section 3(d): new forms of known substances without enhanced efficacy. Many Indian startup inventions, especially software, fintech, and pharma, fail at Section 3 even when novelty is clear. Our search screens Section 3 exclusions upfront so you do not pay to file an unpatentable invention.

What the search delivers

The search report is a working document. It identifies relevant prior art (with bibliographic references, claim mapping, and relevance analysis), assesses patentability on the statutory criteria, flags Section 3 exclusions applicable to your invention, and delivers a clear recommendation: file as-is, amend the claims to avoid identified prior art, redesign around a blocking patent, or abandon if patentability is unlikely. For freedom-to-operate (FTO) searches, the report also identifies granted in-force patents that could block commercialisation of your product.

What Gets Done Each Cycle.

Six search types across the patent practice. Each addresses a different question; the right one for you depends on what decision the search will inform.

Patentability / novelty search
Pre-filing
The most common search. Assesses whether your invention is new and inventive against worldwide prior art. Output: file-as-is, amend claims, redesign, or abandon recommendation. Done before drafting the patent application; shapes the claim strategy.
Freedom-to-operate (FTO) search
Pre-launch
Identifies granted, in-force patents that could block commercialisation of your product, regardless of whether you patent yours. Critical before product launch, especially in regulated industries. Different from novelty search: focuses on enforceability, not patentability.
Prior art search
Pre-filing
Broader than novelty: maps the full prior art landscape in a technical domain. Used to draft strong, defensible claims that distinguish from existing knowledge. Particularly useful in crowded technical fields where novelty is incremental.
Validity / invalidity search
Litigation
Reviews the strength of an existing patent, yours or a competitor's. Used in opposition, revocation proceedings, infringement defence, and licensing negotiations. Search the prior art that may not have been before the examiner when the patent was granted.
Patent landscape analysis
Strategic
Maps competitor portfolios, technology trends, and white space in a domain. Used for R&D direction setting, M&A diligence, and entering a new technology area. Output: visual maps, filing trends, top assignees and inventors, and white-space recommendations.
Patent watch & monitoring
Standing
Ongoing surveillance of newly published patents in a defined technology domain or by named competitors. Quarterly or monthly reports flag relevant new filings. Useful for keeping ahead of FTO risks and identifying licensing opportunities.

When You Need Us to Handle This.

Patent search quality directly determines whether your filing strategy is built on real information or hopeful assumptions. Here's when professional handling pays back and when self-search is feasible.

Get help if
  • You're about to file a patent application. Filing without a search means paying government fees, examination fees, and prosecution costs for an invention that may be rejected on novelty or inventive step. The search cost is a fraction of the filing cost. Skipping the search is the most expensive shortcut in patent practice.
  • Your invention is software, fintech, or business-process driven. Section 3(k) excludes software per se and business methods. The line between patentable technical innovation and excluded software is narrow and case-specific. A search screens Section 3 exclusions before you pay to discover them at examination.
  • You're launching a product in a competitive technical space. Freedom-to-operate (FTO) searches identify granted patents that could block your launch, regardless of whether you have your own patents. FTO is risk management for product launches, not patent strategy. Critical in regulated industries.
  • You're raising capital or doing M&A and need IP diligence. Investors and acquirers want patent landscape analyses and FTO assessments before they price the deal. Self-prepared searches do not carry credibility in diligence. Independent search reports do.
  • You've been served with a patent infringement notice. Validity / invalidity searches are the standard defence: find prior art the examiner did not have, attack the patent's validity, and use that as leverage. This is highly technical work; self-search is rarely sufficient against a serious infringement claim.
Consider DIY if
  • You're at the early ideation stage and exploring patentability informally. InPASS is free and the basic keyword search is usable. Google Patents is free and convenient. A rough self-search to check if your idea has obvious prior art is useful before deciding whether to commission a professional search.
  • You have an in-house patent team or a registered Patent Agent. Established R&D-heavy companies with in-house patent practitioners handle most searches internally. External help is typically engaged for jurisdiction-specific searches, very large landscape studies, or validity searches in litigation context.
  • Your invention is in a niche where the prior art is limited and well-known to you. Some technical fields have small, well-mapped prior art landscapes. If you and your team already know the relevant patents and publications, a confirmatory self-search may be enough.
  • The patent is not commercially significant enough to justify professional search fees. Defensive filings (where you do not plan to enforce or license the patent) and exploratory filings (where the cost of refusal is acceptable) may proceed without a thorough search.

How We Work.

Six commitments. A CA-led IP team in partnership with registered Patent Agents (technical and legal practitioners under Section 126 of the Patents Act 1970), assessing patentability with rigour and writing reports you can hand to your filing counsel.

NDA signed before invention disclosure
Non-disclosure agreement executed before you share any technical detail. India's patent law treats prior public disclosure as a novelty bar; we treat your invention as confidential from first contact. NDA covers our team and any registered Patent Agent partner brought into the engagement.
Patentability report in 2-4 weeks
Standard patentability search delivered in 2-4 weeks from complete brief. FTO and landscape analyses take 4-8 weeks. Validity searches in active litigation context can be expedited. Timeline agreed and committed at engagement start.
Multi-database search, not InPASS alone
InPASS (official Indian database, free) + Espacenet (worldwide via European Patent Office) + WIPO PATENTSCOPE (international PCT) + USPTO + EPO + Google Patents combined. Search uses IPC classifications, keywords, citation chains, and inventor / assignee lookups. Single-database searches miss prior art.
Section 3 exclusions screened upfront
Software, business methods, mathematical methods, traditional knowledge, abstract ideas, all flagged before search effort is spent. Many Indian startup inventions fail at Section 3, not novelty. We tell you upfront if your invention has a Section 3 problem.
Registered Patent Agent on the report
Search analysis reviewed by a registered Patent Agent (Section 126 of the Patents Act 1970) before delivery. Patent Agent's name on the report. Engagement structured as advisory; if you proceed to filing, Patent Agent files Form 1 + Form 2 (specification) under their registration.
Patent watch as standing engagement
Ongoing monitoring of newly published patents in your technology domain or by named competitors. Quarterly or monthly reports flag relevant new filings. Useful for keeping ahead of FTO risks and identifying licensing or M&A opportunities. Separate engagement; predictable retainer.

What a Patent Search Catches Before You File.

A patent search is advisory, not mandatory. But the things it catches, each of which would otherwise turn into a refusal, an FTO crisis, or a litigation surprise, are why search-then-file is the standard approach in serious patent practice.

Search cost is a fraction of filing cost; filing without searching is the most expensive shortcut
No statutory requirement to search before filing in India. But across patent practice, search-then-file is the standard for serious commercial filings, because every one of the items above is cheaper to catch at search stage than to discover at examination, opposition, or litigation stage.

Frequently Asked Questions.

No. The Patents Act 1970 does not require an applicant to conduct a search before filing. However, in serious commercial practice, search-then-file is the standard. A search costs a fraction of filing fees and prosecution costs and prevents the largest avoidable expense: filing, paying examination fees, responding to First Examination Reports, and ultimately being refused on novelty or inventive step grounds. The search is advisory; the decision to file is yours, but the search shapes whether you file as-is, amend claims, redesign, or abandon.
Patentability (novelty) search: Will my invention qualify for a patent? Looks at all prior art, granted and abandoned, published worldwide, anywhere in the world before the priority date. Freedom-to-operate (FTO) search: Can I commercialise my product without infringing someone else's patent? Looks only at granted, in-force patents in the jurisdictions where you intend to sell. The two searches answer different questions. You can have a patentable invention that is not free to operate (a competitor's patent covers a part you must use). You can have freedom to operate but no patentable invention. Many companies need both.
Standard patentability search: 2-4 weeks from complete brief to delivered report. Freedom-to-operate (FTO) and landscape analyses: 4-8 weeks because they cover more granted patents in greater depth. Validity / invalidity searches in active litigation context can be expedited to 1-2 weeks if needed. Timeline depends on technical complexity and number of jurisdictions. We agree timeline and committed delivery date at engagement start.
InPASS (Indian Patent Advanced Search System) is the official IPO database, publicly accessible at iprsearch.ipindia.gov.in. It covers published and granted Indian patents. It is free to use. Anyone can search it for keyword, application number, applicant, or IPC classification. A professional search uses InPASS as a starting point but adds Espacenet (European Patent Office, worldwide), WIPO PATENTSCOPE (international PCT), USPTO, EPO, and proprietary databases; combines keyword + IPC + citation + inventor / assignee strategies; and provides an interpretive opinion on patentability and Section 3 exclusions. A search list is not a search.
Section 3 of the Patents Act 1970 excludes specific categories from patentability regardless of novelty or inventive step. Most relevant for Indian startups: Section 3(k): mathematical methods, business methods, and computer programs per se (the “per se” matters, software with technical effect may be patentable; pure software is not). Section 3(m): schemes for mental acts or playing games. Section 3(p): traditional knowledge. Section 3(d): new forms of known substances without enhanced efficacy (relevant in pharma). Many Indian fintech, AI, and software inventions fail at Section 3 even when novelty and inventive step are clear. Our search screens Section 3 upfront.
Software per se is excluded under Section 3(k). However, software that produces a technical effect beyond the program itself, software combined with hardware, software solving a technical problem, software with measurable technical contribution, can be patentable. The line is case-specific and the Indian Patent Office's position has evolved through case law (notably Ferid Allani v Union of India, 2019, and subsequent CGPDTM guidelines). For software inventions, the search assesses both novelty AND Section 3(k) defensibility before recommending a filing strategy.
Yes, we need to understand the technical features to conduct a meaningful search. We sign a non-disclosure agreement (NDA) before any technical disclosure. The NDA covers our team and any registered Patent Agent partner brought into the engagement. Indian patent law treats prior public disclosure as a novelty bar, you must not publicly disclose the invention before filing (limited exceptions exist for certain disclosures within 12 months under Section 31). We treat your invention as confidential throughout the engagement.
A typical patentability search report includes: Executive summary with the patentability opinion and recommendation; Invention description as we understood it; Search strategy documenting databases, keywords, IPC classifications, and citation chains used; Relevant prior art with bibliographic references (publication number, date, title, assignee, jurisdiction); Claim-by-claim analysis mapping prior art to invention features; Section 3 assessment if applicable; Recommendation: file as-is, amend claims, redesign around prior art, or abandon. The report is written so you can hand it directly to filing counsel.
Pricing depends on: (1) search type, patentability searches are predictably priced; FTO and landscape analyses are higher because they cover more granted patents; validity searches are quoted per case; (2) technical complexity, mechanical or chemical inventions search differently than software or biotech; (3) jurisdictions, India-only vs India + US + EP + WIPO; (4) turnaround, standard vs expedited. We quote a fixed fee for the engagement once the scope is defined; no surprise billing. Reach out for a specific quote.
Yes. Patent filing in India must be conducted by a registered Patent Agent under Section 126 of the Patents Act 1970. We partner with registered Patent Agent firms and coordinate the filing under their registration. The search report becomes the input to the provisional or complete specification. If you prefer to use your own Patent Agent for filing, the search report is structured to hand off directly to them, no rework required.
Sometimes, yes. If you have a public disclosure date approaching (a product launch, a conference presentation, a publication), filing a provisional patent application immediately establishes a priority date under Section 9 of the Patents Act, even before the search is complete. The complete specification (Form 2) can be filed within 12 months of the provisional. The search can run in parallel and inform the complete specification. We can advise on the right sequence based on your timeline and risk tolerance.
Yes, this is the validity / invalidity search. The objective is to find prior art that was not before the examiner when the competitor's patent was granted, prior art that, if applied, would have prevented or narrowed the grant. The found prior art is used in pre-grant opposition (before the patent is granted, under Section 25(1)), post-grant opposition (within 1 year of grant, Section 25(2)), revocation proceedings (Section 64), or infringement defence. The search is highly technical and the analysis must be airtight. We typically partner with patent litigation counsel for these searches.
