What this shows Cnbm's Innovation Score is 53.8/100 (top 8% 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 Cnbm?

Each dot is one of Cnbm’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). Cnbm’s own 15.4 claims/patent is ABOVE the 9.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cnbm's grants concentrate

Cnbm Research Institute FOR Advanced Glass Materials Group Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 73.3% of grants classified under H10F (Inorganic Semiconductor Devices Sensitive TO Infrared Radiation, Light, Electromagnetic Radiation OF Shorter Wavelength OR Corpuscular Radiation). Peak complete grant year is 2024 (6 grants) versus a trough of 2 in 2022. By volume, Cnbm sits between CHU Nantes and Coriolis Group.

Cnbm's three-year grant acceleration

Cnbm Research Institute FOR Advanced Glass Materials Group Co., Ltd. shows 12 grants in 2022–2024 against only 0 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.
