What this shows Kortek's Innovation Score is 50.2/100 (top 13% 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 Kortek?

Each dot is one of Kortek’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). Kortek’s own 8.2 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kortek's grants concentrate

Kortek Corporation is a focused PatentsView assignee: 16 CPC subclasses with 45.8% of grants classified under G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2015. By volume, Kortek sits between KM Biologics Co., Ltd. and Kurashiki Boseki Kabushiki Kaisha.

Kortek's three-year grant acceleration

Kortek Corporation shows 14 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.
