What this shows Qualicaps's Innovation Score is 46.8/100 (top 20% 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 Qualicaps?

Each dot is one of Qualicaps’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). Qualicaps’s own 12.4 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qualicaps's grants concentrate

Qualicaps Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 50% of grants classified under A61J (Containers Specially Adapted FOR Medical OR Pharmaceutical PURPOSES; Devices OR Methods Specially Adapted FOR Bringing Pharmaceutical Products Into Particular Physical OR Administering FORMS; Devices ). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2024. By volume, Qualicaps sits between Pura Scents, Inc. and Quintus Technologies AB.

Qualicaps's three-year grant acceleration

Qualicaps Co., Ltd. shows 4 grants in 2022–2024 against only 2 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.
