In India you can patent agricultural machinery, irrigation and sensing devices, drones, fertiliser and pesticide compositions with a synergistic effect, and new food-processing methods and equipment. Section 3(h) excludes methods of agriculture or horticulture, and Section 3(j) excludes plants, seeds, plant varieties and essentially biological processes. New plant varieties can instead be protected under the Protection of Plant Varieties and Farmers' Rights Act, 2001.

Usually patentable
- Farm machinery, implements, harvesters and post-harvest equipment
- Irrigation systems, soil and crop sensors, agri-drones and their control systems
- Fertiliser, bio-stimulant and pesticide compositions with a synergistic effect
- Food-processing and preservation methods and equipment
- Micro-organisms and processes using them (with deposit and disclosure requirements)
Usually not patentable
- A method of farming or growing crops (Section 3(h))
- Plants, seeds, varieties and essentially biological breeding processes (Section 3(j))
- Simple mixtures of known ingredients, including most recipes (Section 3(e))
- Traditional knowledge, such as known uses of neem or turmeric (Section 3(p))
The two big exclusions
Section 3(h) excludes "a method of agriculture or horticulture": a new way of sowing, spacing, pruning or rotating crops. Section 3(j) excludes "plants and animals in whole or any part thereof other than micro-organisms", including seeds, varieties and species, and essentially biological processes for producing them.
The equipment and products used in farming are not excluded. So the way to protect an agri-innovation is usually to claim the machine, device, system or composition, not the farming method.
| Excluded | Patentable alternative |
|---|---|
| A method of growing tomatoes hydroponically | A hydroponic system with a new nutrient-dosing and sensing arrangement |
| A new wheat variety | Protect under the PPVFR Act, 2001; a new seed-coating composition may be patentable |
| A method of spraying crops at a certain time | A drone with a new spray-control system that adjusts flow to crop density |
| A family recipe for pickle | A new preservation process that extends shelf life without preservatives, with test data |
Plant varieties: use the PPVFR Act
New, distinct, uniform and stable plant varieties can be registered under the Protection of Plant Varieties and Farmers' Rights Act, 2001, administered by the PPV&FR Authority. Farmers' varieties and extant varieties can also be registered.
Compositions need data
Fertiliser, bio-pesticide and feed compositions are often refused under Section 3(e) as mere mixtures. Field or lab data showing a synergistic effect (better yield or pest control than the ingredients separately) is what gets them granted. If the composition uses Indian plants, microbes or traditional knowledge, check Section 3(p), disclose the source of biological material, and plan for National Biodiversity Authority approval before grant.
Food products and recipes
Most recipes are mixtures of known ingredients and can't be patented, and publishing them is risky. A new process (for example, a way of drying, extracting or preserving that gives a measurable result) or equipment can be patented. Otherwise, a secret recipe plus a strong trademark is often the better strategy.
Student and university innovations
Many agritech inventions come from agricultural universities and student projects. Educational institutions and startups pay lower official fees, and startups can also request expedited examination. See patent fee benefits.
Frequently asked questions
Can I patent a new farming technique in India?
No. Methods of agriculture and horticulture are excluded under Section 3(h). You can patent a new machine, device or system used to carry out the technique.
Can seeds or a new crop variety be patented in India?
No. Plants, seeds and varieties are excluded under Section 3(j). New varieties can be registered under the Protection of Plant Varieties and Farmers' Rights Act, 2001.
Can I patent my food recipe?
Usually not, because a mixture of known ingredients falls under Section 3(e). A new food-processing method or equipment with a technical result can be patented. Many brands keep recipes as trade secrets instead.
Can micro-organisms be patented?
Yes. Micro-organisms are not excluded by Section 3(j), though naturally occurring ones are discoveries under Section 3(c). Genetically modified or isolated micro-organisms with a new use in a process can qualify, with deposit and source disclosure.
