What this shows Cellutech's Innovation Score is 38.6/100 (top 40% 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 Cellutech?

Each dot is one of Cellutech’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). Cellutech’s own 17.2 claims/patent is at or below the 19.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cellutech's grants concentrate

Cellutech AB is a focused PatentsView assignee: 23 CPC subclasses with 55.6% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Cellutech sits between Celeno Communications Ltd. and Certona Corporation.

Cellutech's three-year grant acceleration

Cellutech AB shows 1 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.
