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 rank #5,613 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. The composite Innovation Score of 47.8/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2021 through 2025, with 61 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. NINGBO TUOTUO RIVER DESIGN COMPANY's 2.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NINGBO TUOTUO RIVER DESIGN COMPANY against peers pursuing similar technology classes.

How to use this portfolio

Ningbo's 61 grants land it in the top 18% by Innovation Score — but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance — Ningbo ranks #5,613 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F16M — see who else leads that technology area. F16M leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity — not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
