Does more volume mean deeper claims for Freeport?
Each dot is one of Freeport’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). Freeport’s own 17.5 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Freeport's grants concentrate
Freeport Minerals Corporation is a focused PatentsView assignee: 17 CPC subclasses with 80% of grants classified under C22B (Production AND Refining OF Metals ; Pretreatment OF RAW Materials). Peak complete grant year is 2024 (13 grants) versus a trough of 2 in 2016. By volume, Freeport sits between Erasmus University Medical Center Rotterdam and Grail, Inc..
Freeport's three-year grant acceleration
Freeport Minerals Corporation shows 22 grants in 2022–2024 against only 10 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.
