USPTO PatentsView assignee record - 297 granted patents across 112 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B24C (ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL).
The verdict
Sintokogio holds 297 US patents across 112 technology areas, rank #1,417 of 50,000 tracked assignees.
Sintokogio, Ltd. has been granted 297 US utility patents between 2015 and 2025, placing Sintokogio, Ltd. at rank #1,417 across all assignees tracked by PlainPatent. This portfolio spans 112 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in B24C (ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL). As a Foreign Corporation, Sintokogio, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sintokogio sits between University Of Tennessee Research Foundation (298 patents, rank #1,413) and Flextronics AP, Llc (295 patents, rank #1,421) - the closest US assignees by grant volume. The composite Innovation Score of 61.8/100 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. Between 2020 and 2025 the company received 166 grants, compared with 131 in the 2015–2019 window, a +27% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sintokogio, Ltd.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sintokogio, Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Sintokogio's 297 grants land it in the top 3% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
