Across all tracked assignees
USPTO PatentsView assignee record — 87 granted patents across 42 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A01N (PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF ; BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES ; PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS).
ISHIHARA SANGYO KAISHA, LTD. has been granted 87 US utility patents between 2015 and 2025, placing ISHIHARA SANGYO KAISHA, LTD. at rank #4,120 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in A01N (PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF ; BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES ; PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS). As a Foreign Corporation, ISHIHARA SANGYO KAISHA, LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.9/100 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 30 grants, compared with 57 in the 2015–2019 window — a -47% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ISHIHARA SANGYO KAISHA, LTD.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ISHIHARA SANGYO KAISHA, LTD. against peers pursuing similar technology classes.
