What this shows Mems's Innovation Score is 49.4/100 (top 15% 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 Mems?

Each dot is one of Mems’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). Mems’s own 14.9 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mems's grants concentrate

Mems Drive (NANJING) Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 93.8% of grants classified under H02N (Electric Machines NOT Otherwise Provided FOR). Peak complete grant year is 2022 (7 grants) versus a trough of 2 in 2023. By volume, Mems sits between Matroid, Inc. and Metail Limited.

Mems's three-year grant acceleration

Mems Drive (NANJING) Co., Ltd. shows 12 grants in 2022–2024 against only 3 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.
