What this shows Letinar's Innovation Score is 48.6/100 (top 16% 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 Letinar?

Each dot is one of Letinar’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). Letinar’s own 13.3 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Letinar's grants concentrate

Letinar Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2024 (11 grants) versus a trough of 2 in 2020. By volume, Letinar sits between L&T Technology Services Limited and Lippert Components Manufacturing, Inc..

Letinar's three-year grant acceleration

Letinar Co., Ltd shows 17 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.
