What this shows Bellson's Innovation Score is 45.1/100 (top 24% 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 Bellson?

Each dot is one of Bellson’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). Bellson’s own 14.8 claims/patent is ABOVE the 10.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Bellson's grants concentrate

Bellson Electric PTY Ltd is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2021. By volume, Bellson sits between Beijing Zenithnano Technology Co., Ltd. and Benit M Co., Ltd..

Bellson's three-year grant acceleration

Bellson Electric PTY Ltd shows 4 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.
