What this shows TBS's Innovation Score is 35.0/100 (49th 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 TBS?

Each dot is one of TBS’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). TBS’s own 16.8 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where TBS's grants concentrate

TBS Engineering Limited is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2016. By volume, TBS sits between Taicang Kingfu Plastic Manufacture Co., Ltd. and Team IP Holdings, LLC.

TBS's three-year grant acceleration

TBS Engineering Limited shows 5 grants in 2022–2024 against only 8 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.
