Patent trends / technology filing-trend analysis for a tech field or CPC class.

For R&D-strategy and competitive-intelligence agents. Worldwide.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison.
