What this shows SAN's Innovation Score is 42.7/100 (top 30% 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 SAN?

Each dot is one of SAN’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). SAN’s own 7.9 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 SAN's grants concentrate

SAN Fang Chemical Industry Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 48.4% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2016. By volume, SAN sits between Resolution Products, LLC and Shenzhen Capchem Technology Co., Ltd..

SAN's three-year grant acceleration

SAN Fang Chemical Industry Co., Ltd. shows 10 grants in 2022–2024 against only 8 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.
