What this shows Tianjin's Innovation Score is 39.6/100 (top 38% 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 Tianjin?

Each dot is one of Tianjin’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). Tianjin’s own 6.5 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tianjin's grants concentrate

Tianjin Yunda Industry and Trade Co., Ltd, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 45.5% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2018. By volume, Tianjin sits between ThreatSTOP, Inc. and Tilera Corporation.

Tianjin's three-year grant acceleration

Tianjin Yunda Industry and Trade Co., Ltd, Inc. shows 8 grants in 2022–2024 against only 0 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.
