What this shows LJ's Innovation Score is 30.0/100 (33rd percentile 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 LJ?

Each dot is one of LJ’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). LJ’s own 13.9 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where LJ's grants concentrate

LJ Star, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 71.4% 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 2021 (3 grants) versus a trough of 1 in 2016. By volume, LJ sits between Liposonix, Inc. and Lobo Systems Limited.

LJ's three-year grant acceleration

LJ Star, Inc. shows 2 grants in 2022–2024 against only 4 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.
