What this shows Tsrc's Innovation Score is 37.5/100 (top 43% 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 Tsrc?

Each dot is one of Tsrc’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). Tsrc’s own 14.2 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tsrc's grants concentrate

Tsrc Corporation is a focused PatentsView assignee: 18 CPC subclasses with 57.1% of grants classified under C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Tsrc sits between Transound Electronics Co., Ltd. and Techtronic Outdoor Products Technology Limited.

Tsrc's three-year grant acceleration

Tsrc Corporation shows 3 grants in 2022–2024 against only 6 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.
