What is a Patent?

A patent is an exclusive right granted by the government to an inventor for a new invention, giving them the right to exclude others from making, using, selling, or importing the patented invention for a limited period (typically 20 years from the filing date). In return, the inventor must publicly disclose the complete technical details of the invention, contributing to the pool of human knowledge. Patents are granted for inventions that meet three fundamental criteria: novelty (new and not previously known), inventive step (non-obvious to a person skilled in the field), and industrial applicability (capable of being manufactured or used in industry).

Types of Patents

Patents are classified into: (1) Utility patents — the most common type, covering new and useful processes, machines, articles of manufacture, or compositions of matter; (2) Design patents — protecting ornamental designs of functional items; and (3) Plant patents (in the US) — granted for new, distinct, and asexually reproduced plant varieties. In India, the Patents Act, 1970 (as amended in 2005) primarily covers product and process patents. The 2005 amendment made India TRIPS-compliant by introducing product patents in all fields, including pharmaceuticals and agrochemicals.

Patent Filing Process in India (Indian Patent Office — IPO)

The patent filing process in India involves several stages:

1. Prior art search — examining existing patents and publications to confirm novelty
2. Patent application filing — submitting a provisional or complete specification with claims, abstract, and drawings to the IPO (offices in Delhi, Mumbai, Chennai, and Kolkata)
3. Publication — the application is published in the Official Journal 18 months after filing (or earlier upon request)
4. Examination — a formal request for examination must be filed within 48 months of the filing date; the patent examiner reviews for novelty, inventive step, and industrial applicability
5. First Examination Report (FER) — the examiner's report identifying objections, which the applicant must address within 12 months
6. Grant — if all objections are resolved, the patent is granted and published in the Patent Journal
7. Maintenance — annual renewal fees must be paid to keep the patent in force for up to 20 years

Patent Claims and Infringement

Patent claims are the legally operative part of a patent that defines the scope of protection. They are carefully drafted statements describing exactly what the invention covers. Patent infringement occurs when someone makes, uses, sells, or imports a patented invention without the patent holder's permission. Infringement can be direct (exact copying) or indirect (contributing to or inducing infringement). In India, patent infringement cases are handled by the High Court, which can grant injunctions, damages, and costs.

Notably, certain activities are not considered infringement in India: use for research or educational purposes, preparation of medicines by medical practitioners, and government use for public non-commercial purposes.

Quick Revision

• Patents protect technical inventions, not abstract ideas.
• Full disclosure is mandatory in exchange for time-bound exclusivity.
• Patent strategy is central for agri-biotech and machinery innovation.

Exam Traps

• Discovery and invention are not the same in patent law.
• Patent grant does not equal freedom to operate in all markets.
