What this shows Inventronics's Innovation Score is 37.4/100 (top 44% 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 Inventronics?

Each dot is one of Inventronics’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). Inventronics’s own 12.8 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Inventronics's grants concentrate

Inventronics (HANGZHOU), Inc. is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2019. By volume, Inventronics sits between Intelgenx Corp. and Ipcomm.

Inventronics's three-year grant acceleration

Inventronics (HANGZHOU), Inc. shows 2 grants in 2022–2024 against only 1 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.
