What this shows Catalyst's Innovation Score is 22.5/100 (10th 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 Catalyst?

Each dot is one of Catalyst’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). Catalyst’s own 3.5 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Catalyst's grants concentrate

Catalyst Medium Four, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 16.7% of grants classified under A45C (PURSES; LUGGAGE; Hand Carried Bags). Peak complete grant year is 2020 (10 grants) versus a trough of 1 in 2024. By volume, Catalyst sits between Crrc Tangshan Co., Ltd. and Comcast Cable Holdings, LLC.

Catalyst's three-year grant acceleration

Catalyst Medium Four, Inc. shows 5 grants in 2022–2024 against only 15 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.
