Does more volume mean deeper claims for KEY?

Each dot is one of KEY’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). KEY’s own 34.3 claims/patent is ABOVE the 6.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where KEY's grants concentrate

KEY DH IP INC./IP Strategiques DH, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under C25B (Electrolytic OR Electrophoretic Processes FOR THE Production OF Compounds OR NON-METALS; Apparatus Therefor). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2024. By volume, KEY sits between Kejser, LLC and Kietta.

KEY's three-year grant acceleration

KEY DH IP INC./IP Strategiques DH, Inc. shows 7 grants in 2022–2024 against only 0 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.
