What this shows Ruentex's Innovation Score is 42.2/100 (top 31% 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 Ruentex?

Each dot is one of Ruentex’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). Ruentex’s own 13.9 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ruentex's grants concentrate

Ruentex Engineering & Construction Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 55.6% of grants classified under E04C (Structural ELEMENTS; Building Materials). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2024. By volume, Ruentex sits between ROE Visual Co Ltd and Recurium IP Holdings, LLC.

Ruentex's three-year grant acceleration

Ruentex Engineering & Construction Co., Ltd. shows 9 grants in 2022–2024 against only 13 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.
