What this shows Polatechno's Innovation Score is 33.7/100 (45th 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 Polatechno?

Each dot is one of Polatechno’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). Polatechno’s own 13.2 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Polatechno's grants concentrate

Polatechno Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 94.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2020. By volume, Polatechno sits between PGT Innovations, LLC and Preco, LLC.

Polatechno's three-year grant acceleration

Polatechno Co., Ltd. shows 2 grants in 2022–2024 against only 5 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.
