Portfolio overview
ASAHI GLASS CO., LTD. has been granted 411 US utility patents between 2015 and 2024, placing ASAHI GLASS CO., LTD. at rank #1,052 across all assignees tracked by PlainPatent. This portfolio spans 121 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 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, ASAHI GLASS CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 56.1/100 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 11 grants, compared with 400 in the 2015–2019 window — a -97% 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. ASAHI GLASS CO., LTD.'s 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ASAHI GLASS CO., LTD. against peers pursuing similar technology classes.
