What this shows Cdgm's Innovation Score is 40.6/100 (top 35% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Cdgm?

Each dot is one of Cdgm’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Cdgm’s own 19.8 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cdgm's grants concentrate

Cdgm Glass Co., Ltd is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under 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). Peak complete grant year is 2019 (9 grants) versus a trough of 1 in 2021. By volume, Cdgm sits between Blazer and Flip Flops, Inc. and CPG Interational LLC.

Cdgm's three-year grant acceleration

Cdgm Glass Co., Ltd shows 10 grants in 2022–2024 against only 12 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
