What this shows ESS's Innovation Score is 37.9/100 (top 42% 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 ESS?

Each dot is one of ESS’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). ESS’s own 18.1 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ESS's grants concentrate

ESS 2 Tech, LLC is a focused PatentsView assignee: 13 CPC subclasses with 62.5% of grants classified under F05D (Indexing Scheme FOR Aspects Relating TO Non-positive-displacement Machines OR Engines, Gas-turbines OR Jet-propulsion Plants). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, ESS sits between Epalex Corporation and Europlasma NV.

ESS's three-year grant acceleration

ESS 2 Tech, LLC 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.
