What this shows RTL's Innovation Score is 49.7/100 (top 14% 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 RTL?

Each dot is one of RTL’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). RTL’s own 19.0 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where RTL's grants concentrate

RTL Materials Ltd is a focused PatentsView assignee: 26 CPC subclasses with 46.2% of grants classified under E04C (Structural ELEMENTS; Building Materials). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, RTL sits between Rokform IP LLC and Raven SR, Inc..

RTL's three-year grant acceleration

RTL Materials Ltd shows 5 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.
