Portfolio overview

Ningbo Tuotuo River Design Company has been granted 61 US utility patents between 2021 and 2025, placing Ningbo Tuotuo River Design Company at #5,616 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.2 claims per patent with primary concentration in F16M (FRAMES, CASINGS OR BEDS OF ENGINES, MACHINES OR APPARATUS, NOT SPECIFIC TO ENGINES, MACHINES OR APPARATUS PROVIDED FOR ELSEWHERE; STANDS; SUPPORTS). As a Foreign Corporation, Ningbo Tuotuo River Design Company is one of the more focused assignees in the PatentsView dataset. By volume, Ningbo sits between Moxa Inc. (61 patents, rank #5,609) and OP Solutions, Llc (61 patents, rank #5,617) - the closest US assignees by grant volume. The composite Innovation Score of 47.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 61 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Ningbo Tuotuo River Design Company's 2.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 12 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
