What this shows Cellseed's Innovation Score is 30.3/100 (34th 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 Cellseed?

Each dot is one of Cellseed’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). Cellseed’s own 13.5 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cellseed's grants concentrate

Cellseed Inc. is a focused PatentsView assignee: 11 CPC subclasses with 90% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2020. By volume, Cellseed sits between Ccdi Composites, Inc. and Centre FOR Development OF Telematics.

Cellseed's three-year grant acceleration

Cellseed Inc. shows 1 grants in 2022–2024 against only 3 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.
