Portfolio overview
KEIWA INCORPORATED has been granted 50 US utility patents between 2015 and 2025, placing KEIWA INCORPORATED at rank #6,667 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, KEIWA INCORPORATED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.2/100 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 29 grants, compared with 21 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. KEIWA INCORPORATED's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KEIWA INCORPORATED against peers pursuing similar technology classes.
