Does more volume mean deeper claims for House?

Each dot is one of House’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). House’s own 16.4 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where House's grants concentrate

House OF Metals Company Limited is a focused PatentsView assignee: 14 CPC subclasses with 66.7% of grants classified under C22B (Production AND Refining OF Metals ; Pretreatment OF RAW Materials). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2019. By volume, House sits between Hoerbiger Automatisierungstechnik Holding GMBH and HTI IP, LLC.

House's three-year grant acceleration

House OF Metals Company Limited shows 9 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.
