What this shows Laserssel's Innovation Score is 40.0/100 (top 37% 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 Laserssel?

Each dot is one of Laserssel’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). Laserssel’s own 5.7 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Laserssel's grants concentrate

Laserssel Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2020. By volume, Laserssel sits between Lang Technik GMBH and Learjet Inc..

Laserssel's three-year grant acceleration

Laserssel Co., Ltd. shows 6 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.
