What this shows Lipac's Innovation Score is 34.1/100 (47th 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 Lipac?

Each dot is one of Lipac’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). Lipac’s own 16.1 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Lipac's grants concentrate

Lipac Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Lipac sits between Limited Liability Company “PEERF” and Liverpool John Moores University.

Lipac's three-year grant acceleration

Lipac Co., Ltd. shows 3 grants in 2022–2024 against only 3 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.
