What this shows Apex's Innovation Score is 34.6/100 (48th percentile 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 Apex?

Each dot is one of Apex’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). Apex’s own 15.5 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Apex's grants concentrate

Apex Microelectronics Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 76% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). Peak complete grant year is 2017 (7 grants) versus a trough of 1 in 2022. By volume, Apex sits between Alexza Pharmaceuticals, Inc. and Arkalumen Inc..

Apex's three-year grant acceleration

Apex Microelectronics Co., Ltd. shows 1 grants in 2022–2024 against only 5 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.
