Across all tracked assignees
USPTO PatentsView assignee record — 363 granted patents across 96 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA).
NIPPON ELECTRIC GLASS CO., LTD. has been granted 363 US utility patents between 2015 and 2025, placing NIPPON ELECTRIC GLASS CO., LTD. at rank #1,172 across all assignees tracked by PlainPatent. This portfolio spans 96 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a Foreign Corporation, NIPPON ELECTRIC GLASS CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 58.5/100 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 212 grants, compared with 151 in the 2015–2019 window — a +40% 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. NIPPON ELECTRIC GLASS CO., LTD.'s 9.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 96 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NIPPON ELECTRIC GLASS CO., LTD. against peers pursuing similar technology classes.
