Why this page exists — and how to read it
A one-page brief of this sector: its filing trend, the problems being worked on, the technologies in play, who files most, foreign interest, and a sample of the startups we've mapped to it. Each panel is a door — most drill into a fuller view.
- Investors
- Read the trend and foreign share first — momentum plus outside interest — then scan the roster for patent-backed startups.
- Founders & operators
- The problems list is a whitespace map: crowded themes are validated demand, thin ones are open ground.
- Corporate & R&D
- Top filers and technologies show who to benchmark and where the sector is consolidating.
- Policy & TTO
- The domestic-vs-foreign filing split signals where Indian players lead — and where outside applicants dominate.
