What this shows Chart's Innovation Score is 51.5/100 (top 11% 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 Chart?

Each dot is one of Chart’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). Chart’s own 16.1 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chart's grants concentrate

Chart Inc. is a focused PatentsView assignee: 25 CPC subclasses with 76.2% of grants classified under F17C (Vessels FOR Containing OR Storing Compressed, Liquefied OR Solidified GASES; Fixed-capacity GAS-HOLDERS; Filling Vessels With, OR Discharging From Vessels, Compressed, Liquefied, OR Solidified Gases). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2020. By volume, Chart sits between Choon's Design LLC and De'longhi Braun Household GMBH.

Chart's three-year grant acceleration

Chart Inc. shows 15 grants in 2022–2024 against only 9 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.
