What this shows I-tek's Innovation Score is 37.0/100 (top 45% 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 I-tek?

Each dot is one of I-tek’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). I-tek’s own 7.7 claims/patent is at or below the 9.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where I-tek's grants concentrate

I-tek Metal MFG. Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 69.6% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2024. By volume, I-tek sits between Horteve Breeding BV and Keysight Technologies Singapore (SALES) Pte. Ltd..

I-tek's three-year grant acceleration

I-tek Metal MFG. Co., Ltd. shows 10 grants in 2022–2024 against only 9 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.
