A sample of matched deep-tech startups - Startup counts are name-matched candidates, not ownership records - see methodology. Methodology
Deep-tech basis: site-backed (own website fetched and read), IP-backed (patent or design filed in its own name), web-backed (described elsewhere on the open web), registry only (registry description alone). How this is decided

Patents publish ~18 months after they're filed, so the current year is always incomplete. The Rising / Steady / Cooling signal ignores it and compares only fully-published years - read a dip in the latest year as data still coming in, not a decline.

Briefings on this technology
tech brief
India's Energy Sector Looks 97% China-Free. Its Batteries Are 75% Chinese.
Energy is India's least China-dependent sector at 2.8%, until you look at lithium-ion cells, which run 75.2% Chinese. It's the one sector where patents, startups and capital point the right way.
