What this shows Tetos's Innovation Score is 20.0/100 (6th 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 Tetos?

Each dot is one of Tetos’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). Tetos’s own 2.7 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tetos's grants concentrate

Tetos Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 66.7% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2018. By volume, Tetos sits between Tenova Advanced Technologies Ltd and Tews Elektronik GmbH & Co. KG.

Tetos's three-year grant acceleration

Tetos Co., Ltd. shows 1 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.
