NANOBIOTIX
NANOBIOTIX is a Public Limited Company registered in France under 44752160000034, and its current status with INPI (Institut National de la Propriété Industrielle) is active. The company was incorporated on 1 March 2003 and lists its registered address as PARIS, France. 2 shareholders are on record for NANOBIOTIX, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from INPI (Institut National de la Propriété Industrielle) and was last updated on 9 September 2026.
