What this shows Chemi's Innovation Score is 28.7/100 (28th 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 Chemi?

Each dot is one of Chemi’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). Chemi’s own 11.6 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chemi's grants concentrate

Chemi S.P.A. is a focused PatentsView assignee: 10 CPC subclasses with 33.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2022. By volume, Chemi sits between Celltrust Corporation and Chongqing Haier Drum Washing Machine Co., Ltd..

Chemi's three-year grant acceleration

Chemi S.P.A. shows 1 grants in 2022–2024 against only 4 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.
