What this shows Cemedine's Innovation Score is 32.4/100 (41st 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 Cemedine?

Each dot is one of Cemedine’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). Cemedine’s own 6.4 claims/patent is at or below the 11.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cemedine's grants concentrate

Cemedine Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 77.8% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2019. By volume, Cemedine sits between Cellomics, Inc. and Centre Scientifique ET Technique DU BÂTIMENT (CSTB).

Cemedine's three-year grant acceleration

Cemedine Co., Ltd. shows 4 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.
