About This Service
Patent Services in India
A patent grants the patentee the exclusive right — under Section 48 of the Patents Act 1970 — to prevent others from making, using, offering for sale, selling or importing the patented product or process without consent. Securing and enforcing a patent requires careful navigation of the technical, legal and procedural requirements at every stage — from initial patentability assessment through filing, prosecution and, where necessary, litigation.
At Ingenious IP LLP, our team of registered patent agents and patent attorneys manages the complete patent lifecycle. We have handled patent applications for Indian and international clients across a wide range of technology domains — from filing and prosecution before the Indian Patent Office to IP strategy, enforcement and litigation support before Indian courts.
We maintain a cloud-based IP portfolio management and docketing system to ensure no critical deadline is missed across a client’s patent portfolio — providing organized, secure and up-to-date tracking of all IP assets and associated deadlines.
What We Offer
Our Patent Prosecution & Litigation Services
We provide comprehensive patent services — from pre-filing searches and drafting through prosecution, litigation and ongoing portfolio management — for inventors, research institutions and businesses.
Patentability Search
A patentability search empowers inventors to assess the patentability of an invention before applying for patent protection. The patentability search report helps in making the final decision about filing a patent application and assists in drafting the patent specification by highlighting the genuine novelty of the invention.
The search report is a comprehensive document that cites similar patents and relevant non-patent literature, helping determine the likelihood of obtaining patent protection for the invention. We search Indian and international patent databases across all relevant technology classes.

Patent Drafting
Patent drafting is the art of writing a patent specification that clearly and concisely describes the invention. A patent specification includes a background of the technical area, a summary of the invention, reference to any drawings, and a detailed description. Special emphasis is given to the unique and innovative aspects of the invention within the claims and description.
It is critical that the specification includes sufficient detail to fully describe all aspects of the invention — while ensuring the claims are carefully drafted to achieve the broadest possible scope of protection that the prior art allows. Our patent drafting team combines technical expertise with legal precision.
To file a patent application in India, an applicant may apply at the branch of the Indian Patent Office having jurisdiction based on the applicant’s place of residence, business or registered address for service. Our team of patent agents and patent attorneys have experience in filing patent applications in India and in multiple countries.
We are fully familiar with the legalities and procedural requirements of patent filing in India — including provisional and complete specifications, convention applications under the Paris Convention, PCT international applications and national phase entries. We maintain a cloud-based IP docketing system to track all filing deadlines across the portfolio.

Patent Prosecution
Patent prosecution is the process of preparing a patent application, filing it with the patent office, and negotiating with the Indian Patent Office to obtain the grant of the patent. Patent prosecution involves responding to examination reports and objections raised by the examining officer, amending claims where necessary, and attending hearings to advance the application to grant.
Patent prosecution is distinct from patent litigation — prosecution is the administrative process before the Patent Office, while litigation involves court proceedings. Our team manages the full prosecution process, including responding to examination reports within prescribed statutory timelines.

Freedom to Operate (FTO) Search
A Freedom to Operate (FTO) search — also called a Right to Use search — is conducted to mitigate the risk of infringing valid patent rights of third parties in a particular region before commercializing a product, launching a new product, process or service. FTO search is a necessary step for R&D, product development and technology companies before market entry.
An FTO search assesses risk — it does not guarantee non-infringement. The analysis reviews in-force patents in the relevant jurisdiction to identify claims that may read on the proposed product or process, enabling the business to make an informed commercialization decision.

Invalidity Search
Whether an organization is facing a patent infringement suit or evaluating a licensing opportunity, an invalidity search is a critical tool in the IP sector. An invalidity search — also called an invalidation or prior art search — identifies prior art that may anticipate or render obvious the claims of a granted patent, potentially providing grounds to challenge the patent’s validity.
The discovery of “killer prior art” — prior art that directly anticipates the asserted claims — can be a decisive outcome of an invalidity search. We employ structured, methodology-driven search strategies to locate the most relevant prior art efficiently.

Patent Watch Service
A patent watch service — also called patent monitoring — involves the continuous observation and tracking of newly published IP data including patent applications and grants in relevant technology areas. Patent watch helps organizations identify potentially infringing patents, licensing and acquisition opportunities, and competitor IP activity in real time.
Patent watch services help businesses minimize the risk of loss of business capital and assets by staying ahead of competitor IP movements and identifying early-stage technology developments in their domain.

Patent Litigation Support
Patent litigation in India has seen a significant increase in recent years — particularly in the pharmaceutical and Standard Essential Patent (SEP) space. We provide structured patent litigation support — including claim chart preparation, infringement analysis, prior art searches for invalidity defence and coordination with litigation counsel for proceedings before Indian District Courts and High Courts.
Parties are also encouraged to explore patent dispute settlement to reduce the burden of litigation. We advise on both enforcement and defence strategies — supporting clients through the complete litigation cycle.
A clear overview of the patent prosecution process in India — from initial assessment through to grant and ongoing maintenance under the Patents Act 1970.
1
Invention Disclosure & Patentability Assessment
The inventor discloses the invention to our team. We assess whether the invention is patentable — evaluating novelty, inventive step and industrial applicability under the Patents Act 1970. We conduct a patentability search to identify prior art and determine the likely scope of protection before committing to a filing strategy.
2
Patent Drafting
Our patent drafting team prepares the patent specification — including the complete technical description, abstract, drawings and carefully crafted patent claims. Claims are drafted to capture the broadest defensible scope of the invention, with dependent claims providing fallback positions. The specification must satisfy the sufficiency of disclosure requirement under the Patents Act 1970.
3
Patent Filing with the Indian Patent Office
The application is filed at the appropriate branch of the Indian Patent Office — based on the applicant’s jurisdiction (Chennai, Delhi, Kolkata or Mumbai). A provisional specification may be filed first to establish a priority date, followed by a complete specification within 12 months. The filing date establishes the priority date for the invention in India.
4
Publication & Request for Examination
Under the Patents Act 1970, a patent application is published 18 months from the filing or priority date. After publication, a Request for Examination (RFE) must be filed to initiate examination — within 48 months of the priority date or filing date, whichever is earlier. An expedited examination option is available for certain applicants including startups and MSME-registered entities.
5
Prosecution — Responding to Examination Reports
The Patent Office issues a First Examination Report (FER) setting out objections to the application. We prepare and file detailed written responses to the FER — addressing each objection through legal argument, technical explanation and, where necessary, claim amendments — within the prescribed statutory timeline. Hearings before the examining officer may also be arranged.
6
Grant & Renewal
Once all objections are overcome, the Patent Office grants the patent. A granted patent in India is valid for 20 years from the date of filing — subject to payment of annual renewal fees from the third year after the date of the application. We track all renewal deadlines to keep the patent in force for its full term.
IP Search Services
Strategic Patent Search Services
Our patent search services provide evidence-based intelligence to support filing decisions, commercialization, enforcement and defence — conducted by experienced patent searchers across all technology domains.
Patentability Search
Identifies prior art to assess novelty and inventive step before filing. Assists in drafting decisions and highlights genuine innovations in the specification — citing comparable patents and pertinent literature from Indian and international databases.
Freedom to Operate (FTO) Search
Assesses infringement risk of a proposed product or process against in-force patents in the target territory. A necessary step before product launch for R&D and product development companies. The search output is a risk assessment — not a legal guarantee of non-infringement.
Invalidity Search
Searches for prior art that anticipates or renders obvious the claims of a granted patent — providing grounds for a validity challenge. Particularly important when facing an infringement allegation or evaluating the strength of an asserted patent. Discovery of “killer prior art” can be a decisive outcome.
Patent Watch & Monitoring
Continuous tracking of newly published patent applications and granted patents in relevant technology domains and against specified assignees — providing timely intelligence on competitor IP activity, licensing opportunities and emerging infringement risks.
Patent Landscape Analysis
Provides a structured overview of the patent landscape in a specific technology domain — identifying key players, technology trends, white spaces and patent clusters. Used for R&D strategy, investment decisions and competitive intelligence.
State of the Art Search
A broad search of the prior art in a technology field to understand the current state of knowledge — supporting R&D planning, patent strategy development and identification of technology gaps where patent protection may be available.
Accurate answers to frequently asked questions about patent prosecution, filing and related search services in India.
Patent prosecution is the administrative process of preparing, filing and negotiating a patent application before the Patent Office — with the objective of obtaining the grant of the patent. It involves responding to examination reports and objections from the Patent Office examiner within statutory timelines.
Patent litigation involves court proceedings — typically a civil suit for patent infringement or a petition for revocation — where parties resolve disputes about patent rights before a competent court. The two processes are entirely distinct.
Under the Patents Act 1970, a granted patent is valid for 20 years from the date of filing of the patent application — not from the date of grant. To keep the patent in force, annual renewal fees must be paid from the third year after the date of the application. Failure to pay renewal fees on time results in the patent lapsing, though restoration may be possible within 18 months from the date of lapse.
A Freedom to Operate (FTO) search — also called a Right to Use search — is conducted to assess whether a proposed product or process can be commercialized in a specific territory without infringing the valid patent rights of third parties. It is a necessary step for R&D, product development and technology companies before commercializing a product, launching a new service or entering a new market.
An FTO search is a risk assessment tool — it does not guarantee non-infringement. The analysis identifies in-force patents with claims that may read on the proposed product or process, helping the business make an informed decision about commercialization.
Under the Patents Act 1970 and Patent Rules 2003, a Request for Examination (RFE) must be filed within 48 months from the date of filing or the priority date of the patent application, whichever is earlier. If an RFE is not filed within this period, the application is treated as withdrawn. An expedited examination option is available for eligible applicants including startups recognized by DPIIT, MSME-registered entities and certain other categories specified by the Patent Office.
A patent watch service — also called patent monitoring or IP watch — is an ongoing service that systematically monitors newly published patent applications and granted patents in specified technology domains or by specified assignees. It helps organizations identify potentially infringing patents, licensing and acquisition opportunities, and competitor IP activity — providing continuous intelligence that helps minimize the risk of adverse impacts on the business from third-party IP activity.
