What this shows Ensco's Innovation Score is 60.6/100 (top 3% 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 Ensco?

Each dot is one of Ensco’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). Ensco’s own 22.7 claims/patent is ABOVE the 18.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ensco's grants concentrate

Ensco, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 50% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2016. By volume, Ensco sits between Dyno Nobel Inc. and Exposure Illumination Architects, Inc..

Ensco's three-year grant acceleration

Ensco, Inc. shows 14 grants in 2022–2024 against only 2 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.
