Portfolio overview
CHUO HATSUJO KABUSHIKI KAISHA has been granted 19 US utility patents between 2015 and 2025, placing CHUO HATSUJO KABUSHIKI KAISHA at rank #15,179 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in F16F (SPRINGS; SHOCK-ABSORBERS; MEANS FOR DAMPING VIBRATION). As a Foreign Corporation, CHUO HATSUJO KABUSHIKI KAISHA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 39.3/100 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 11 grants, compared with 8 in the 2015–2019 window, a +38% 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. CHUO HATSUJO KABUSHIKI KAISHA's 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CHUO HATSUJO KABUSHIKI KAISHA against peers pursuing similar technology classes.
