What this shows Grirem's Innovation Score is 61.4/100 (top 3% 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 Grirem?

Each dot is one of Grirem’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). Grirem’s own 15.6 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Grirem's grants concentrate

Grirem Advanced Materials Co., Ltd. is a focused PatentsView assignee: 33 CPC subclasses with 51.3% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2015. By volume, Grirem sits between GE Renewable Technologies and Goodrich Lighting Systems GmbH & Co. KG.

Grirem's three-year grant acceleration

Grirem Advanced Materials Co., Ltd. shows 20 grants in 2022–2024 against only 7 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.
