Technology Hotbed
Where India's Deep-Tech Is Heading
Data as of 12 Oct 2026Methodology
1,050 technology and theme buckets drawn from 4,84,093 analysed patents, grouped by sector. Each bar is weighted by how many patents map to that technology; the highlighted technologies have their own deep-dive pages.
Startup counts are name-matched candidates, not ownership records - see methodology. Methodology
Patent coverage: 4,84,093 applications, 84.4% filed 2022 onward, 96% carry AI-generated technology tags. Earlier records, back to 2004, are largely granted cases, so pre-2022 years show survivors rather than full filing volume.
Why this page exists - and how to read it
This is the patent record clustered into technology and problem buckets - a bottom-up view of what India's deep-tech is actually working on, weighted by filings rather than by press coverage. Bucket size tells you where effort concentrates; the deep-dive pages show each one's filing trend across fully-published years.
- Investors
- Momentum beats size - a technology's page shows its filing trend across fully-published years (the current, still-publishing year is set aside), so you can see where activity is genuinely building.
- Founders & operators
- Find your space's bucket to see how crowded it is and who already files there - validated demand vs open whitespace.
- Corporate & R&D
- Benchmark your portfolio against each bucket's filers, and watch adjacent buckets for technologies converging on yours.
- Policy & TTO
- Bucket sizes show where national research effort concentrates - and which strategic areas are thin.
💬 Highlighted technologies have deep-dive pages: filing trend, top filers, inventors and a state-by-state filing map.
