Does more volume mean deeper claims for 1304338?

Each dot is one of 1304338’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). 1304338’s own 12.9 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where 1304338's grants concentrate

1304338 Alberta Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 54.5% of grants classified under F25J (Liquefaction, Solidification OR Separation OF Gases OR Gaseous ; OR Liquefied GASEOUS; Mixtures BY Pressure AND Cold Treatment ; OR BY Bringing Them Into THE Supercritical State). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2015. By volume, 1304338 sits between iHear Medical, Inc. and Academisch Medisch Centrum.

1304338's three-year grant acceleration

1304338 Alberta Ltd. shows 5 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.
