What this shows Tianjin's Innovation Score is 42.3/100 (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 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 18.6 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tianjin's grants concentrate

Tianjin Sanan Optoelectronics Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2016. By volume, Tianjin sits between This AG and Titan Wood Limited.

Tianjin's three-year grant acceleration

Tianjin Sanan Optoelectronics Co., Ltd. shows 3 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.
