What this shows TSI's Innovation Score is 58.3/100 (top 5% 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 TSI?

Each dot is one of TSI’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). TSI’s own 17.4 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where TSI's grants concentrate

TSI Group Co., Ltd. is a focused PatentsView assignee: 37 CPC subclasses with 70.7% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2018 (13 grants) versus a trough of 2 in 2016. By volume, TSI sits between THE Timken Company and University OF Cape Town.

TSI's three-year grant acceleration

TSI Group Co., Ltd. shows 22 grants in 2022–2024 against only 12 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.
