What this shows Tangent's Innovation Score is 33.0/100 (43rd 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 Tangent?

Each dot is one of Tangent’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). Tangent’s own 19.1 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tangent's grants concentrate

Tangent Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 77.8% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Tangent sits between Taco Metals LLC and Teal Drones, Inc..

Tangent's three-year grant acceleration

Tangent Co., Ltd. shows 1 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.
