What this shows Balltec's Innovation Score is 32.0/100 (40th 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 Balltec?

Each dot is one of Balltec’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). Balltec’s own 18.0 claims/patent is ABOVE the 17.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Balltec's grants concentrate

Balltec Limited is a focused PatentsView assignee: 9 CPC subclasses with 44.4% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2015. By volume, Balltec sits between Burton Inc. and Basic Holdings.

Balltec's three-year grant acceleration

Balltec Limited shows 2 grants in 2022–2024 against only 5 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.
