The verdict
CDGM holds 37 US patents across 9 technology areas — rank #8,550 of 50,000 tracked assignees.
CDGM GLASS CO., LTD has been granted 37 US utility patents between 2015 and 2025, placing CDGM GLASS CO., LTD at rank #8,550 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.8 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, CDGM GLASS CO., LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.6/100 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 14 grants, compared with 23 in the 2015–2019 window — a -39% 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. CDGM GLASS CO., LTD's 19.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CDGM GLASS CO., LTD against peers pursuing similar technology classes.

How to use this portfolio
CDGM's 37 grants land it in the top 35% by Innovation Score — but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity — not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
