What this shows MGC's Innovation Score is 41.9/100 (top 32% 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 MGC?

Each dot is one of MGC’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). MGC’s own 11.0 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where MGC's grants concentrate

MGC Filsheet Co., Ltd. is a focused PatentsView assignee: 27 CPC subclasses with 59.6% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2018 (9 grants) versus a trough of 1 in 2021. By volume, MGC sits between LSI Industries, Inc. and Marchesini Group S.P.A..

MGC's three-year grant acceleration

MGC Filsheet Co., Ltd. shows 9 grants in 2022–2024 against only 17 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.
