What this shows Tower's Innovation Score is 40.8/100 (top 35% 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 Tower?

Each dot is one of Tower’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). Tower’s own 24.4 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tower's grants concentrate

Tower Ipco Company Limited is a focused PatentsView assignee: 9 CPC subclasses with 66.7% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Tower sits between Tomi Environmental Solutions Inc. and Traxcell Technologies, LLC.

Tower's three-year grant acceleration

Tower Ipco Company Limited shows 3 grants in 2022–2024 against only 3 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.
