What this shows GEM's Innovation Score is 47.8/100 (top 18% 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 GEM?

Each dot is one of GEM’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). GEM’s own 7.2 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where GEM's grants concentrate

GEM Co., Ltd. is a focused PatentsView assignee: 34 CPC subclasses with 46.3% of grants classified under C22B (Production AND Refining OF Metals ; Pretreatment OF RAW Materials). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2020. By volume, GEM sits between Foret Plasma Labs, LLC and Garland Industries, Inc..

GEM's three-year grant acceleration

GEM Co., Ltd. shows 6 grants in 2022–2024 against only 4 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.
