Deep-tech startups with a patent tagged this technology

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

Filing momentum
Filings by year - recent years still publishing

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.
