#1,380
Across all tracked assignees
USPTO PatentsView assignee record — 304 granted patents across 56 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G01B (MEASURING LENGTH, THICKNESS OR SIMILAR LINEAR DIMENSIONS; MEASURING ANGLES; MEASURING AREAS; MEASURING IRREGULARITIES OF SURFACES OR CONTOURS).
KEYENCE CORPORATION has been granted 304 US utility patents between 2015 and 2025, placing KEYENCE CORPORATION at rank #1,380 across all assignees tracked by PlainPatent. This portfolio spans 56 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.0 claims per patent with primary concentration in G01B (MEASURING LENGTH, THICKNESS OR SIMILAR LINEAR DIMENSIONS; MEASURING ANGLES; MEASURING AREAS; MEASURING IRREGULARITIES OF SURFACES OR CONTOURS). As a Foreign Corporation, KEYENCE CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 56.3/100 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 168 grants, compared with 136 in the 2015–2019 window — a +24% 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. KEYENCE CORPORATION's 13.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 56 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KEYENCE CORPORATION against peers pursuing similar technology classes.
