What this shows Assure's Innovation Score is 39.6/100 (top 38% 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 Assure?

Each dot is one of Assure’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). Assure’s own 5.3 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Assure's grants concentrate

Assure Tech. (HANGZHOU) Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 35.7% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2018. By volume, Assure sits between Archangel Device LLC and Aura Technologies, LLC.

Assure's three-year grant acceleration

Assure Tech. (HANGZHOU) Co., Ltd. shows 10 grants in 2022–2024 against only 0 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.
