What this shows Cengage's Innovation Score is 36.7/100 (top 46% 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 Cengage?

Each dot is one of Cengage’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). Cengage’s own 16.8 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cengage's grants concentrate

Cengage Learning, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under G06F (Electric Digital Data Processing). By volume, Cengage sits between Celligence International LLC and Central Boiler, Inc..

Cengage's three-year grant acceleration

Cengage Learning, Inc. shows 2 grants in 2022–2024 against only 0 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.
