Portfolio overview

AOYAMA SEISAKUSHO CO., LTD. has been granted 29 US utility patents between 2015 and 2024, placing AOYAMA SEISAKUSHO CO., LTD. at rank #10,530 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.7 claims per patent with primary concentration in F16B (DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES; JOINTS OR JOINTING). As a Foreign Corporation, AOYAMA SEISAKUSHO CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 36.4/100 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 17 grants, compared with 12 in the 2015–2019 window, a +42% 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. AOYAMA SEISAKUSHO CO., LTD.'s 4.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AOYAMA SEISAKUSHO CO., LTD. against peers pursuing similar technology classes.
