What this shows Siser's Innovation Score is 36.3/100 (top 47% 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 Siser?

Each dot is one of Siser’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). Siser’s own 4.2 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Siser's grants concentrate

Siser NA is a focused PatentsView assignee: 4 CPC subclasses with 16.7% 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 2022 (2 grants) versus a trough of 1 in 2023. By volume, Siser sits between Sinochem Corporation and Sivananthan Laboratories, Inc..

Siser's three-year grant acceleration

Siser NA shows 5 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.
