- Patent Flowchart in India
The patent flowchart in India provides a clear and structured pathway for inventors, entrepreneurs and companies who wish to protect their innovations. It helps applicants visualise each step of the patent application process flowchart, ensuring that deadlines, documentation and legal compliances are not missed.
In India, the patent system is governed by the Patents Act, 1970 and the Patent Rules. While the law can appear complex, the patent flow chart simplifies the process into clear stages. This makes it easier for innovators across the globe to secure protection for their intellectual property in India.
Before diving into detailed explanations, it is helpful to see the entire journey mapped out in a sequence. The patent process flow chart highlights every important milestone from idea to protection. This overview helps inventors and companies plan their strategy in advance.
Idea → Prior art search → Drafting (provisional or complete) → Filing → Publication → Request for Examination → Examination and First Examination Report (FER) → Response and hearing → Opposition (if any) → Grant → Renewal
The patent application flowchart consists of multiple steps, each with its own requirements and timelines. Following them carefully is the key to securing successful grant.
The first stage is to determine if the invention is patentable. A prior art search helps confirm novelty, inventive step and industrial applicability. This step prevents unnecessary filings and increases the chances of a successful grant.
Applicants must choose between filing a provisional or a complete specification:
• Provisional Specification – Useful when the invention is at an early stage. It secures the priority date but must be followed by a complete specification within 12 months.
• Complete Specification – Required when the invention is fully developed, with detailed claims, description, drawings and abstract.
At this stage, the invention is formally filed with the Indian Patent Office. Filing can be done online using prescribed forms and a digital signature. This step marks the official start of the legal protection process.
Every application is published automatically after 18 months from the filing or priority date. However, applicants may request early publication to accelerate the process. Once published, the application enters the public domain.
Examination of the application does not happen automatically. A Request for Examination must be filed within 48 months from the priority date. Without this, the application is treated as withdrawn.
The application is assigned to an examiner who issues a First Examination Report (FER). The FER usually contains objections relating to novelty, inventive step, clarity and formal requirements.
Applicants have six months to reply to the FER, extendable up to nine months. Written responses, claim amendments and hearings may be required before the Controller of Patents.
Patent applications may face opposition at two stages:
• Pre-grant opposition: After publication but before the grant.
• Post-grant opposition: Within one year from the grant of the patent.
Step 9: Grant of Patent
Once objections are resolved and no opposition succeeds, the Controller grants the patent. The details are recorded in the Patent Register and published in the Patent Journal.
Step 10: Renewal
Patents in India last for 20 years from the filing date. Renewal fees must be paid annually starting from the third year to maintain validity.
The patent filing process flowchart is more than a diagram. It is a practical guide that ensures inventors, businesses and legal teams stay aligned. By following it, applicants avoid missing deadlines, reduce objections during examination, and manage their costs efficiently.
The flowchart demonstrates that every stage of the process has a legal purpose. From protecting priority dates to responding to examination reports, each step builds towards a strong and enforceable patent.
Preparing documentation correctly is essential for smooth filing. The patent flowchart in India highlights the specific documents required at different stages. Having them ready avoids delays or rejections.
Indian patent law is strict about deadlines. Missing a single date can lead to loss of rights. The patent process flow chart highlights the most important compliance requirements every applicant must remember.
A structured approach through a patent flowchart offers multiple advantages. It ensures that inventors and companies are able to manage the process strategically while saving time and money.
The Indian patent system is open to a wide variety of applicants. The patent application flowchart applies to individuals, start-ups, and global corporations alike. Anyone who meets the basic eligibility criteria can protect their invention in India.
The following step-by-step patent filing process flowchart can be used as a practical checklist by innovators worldwide. It ensures that no key stage is missed during the journey.
The patent filing process flowchart transforms a complex legal system into a clear and manageable journey. By following each step carefully, inventors can protect their ideas, create commercial opportunities, and gain an edge in global markets.
Start planning today. Map your invention against the patent application process flowchart and move forward with confidence towards securing long-term protection in India.
The process can take between 3 to 5 years depending on the complexity of the invention, backlog at the Patent Office, and objections raised.
No. Filing a provisional is optional. You may file directly with a complete specification if the invention is fully ready.
Form 1, Form 2, Form 3 (if applicable), Form 5, the specification, abstract, and drawings.
If the request is not filed within 48 months, the application is deemed withdrawn and cannot be revived.
A patent remains valid for 20 years from the filing date, provided renewal fees are paid annually.
