Across all tracked assignees
USPTO PatentsView assignee record — 38 granted patents across 36 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE).
Taiheiyo Cement Corporation has been granted 38 US utility patents between 2015 and 2025, placing Taiheiyo Cement Corporation at rank #8,495 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a Foreign Corporation, Taiheiyo Cement Corporation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.3/100 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 19 grants, compared with 19 in the 2015–2019 window — a +0% 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. Taiheiyo Cement Corporation's 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 36 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Taiheiyo Cement Corporation against peers pursuing similar technology classes.
