What this shows Grirem's Innovation Score is 51.3/100 (top 12% 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 17.4 claims/patent is ABOVE the 16.3 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 Hi-tech Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 57.1% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2024 (5 grants) versus a trough of 2 in 2023. By volume, Grirem sits between Grena USA LLC and GTLpetrol Holding Co. LLC.

Grirem's three-year grant acceleration

Grirem Hi-tech Co., Ltd. shows 7 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.
