What this shows Patech's Innovation Score is 24.1/100 (14th 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 Patech?

Each dot is one of Patech’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). Patech’s own 13.0 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Patech's grants concentrate

Patech Fine Chemicals Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under C10M (Lubricating Compositions ; USE OF Chemical Substances Either Alone OR AS Lubricating Ingredients IN A Lubricating Composition). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, Patech sits between Parker Intangibles LLC and Paul Muller GMBH & Co. KG Unternehmensbeteiligungen.

Patech's three-year grant acceleration

Patech Fine Chemicals Co., Ltd. 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.
