Technology Hotbed
Where India's Deep-Tech Is Heading
1,050 technology and theme buckets drawn from 4,50,060 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
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 tell you whether it's accelerating.
- Investors
- Momentum beats size — open a technology's page and check whether filings are accelerating or fading before reading its rank.
- 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.
