Does more volume mean deeper claims for Coorstek?
Each dot is one of Coorstek’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). Coorstek’s own 8.6 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Coorstek's grants concentrate
CoorsTek, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 26.7% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2022. By volume, Coorstek sits between Compellent Technologies and Cosman Instruments, LLC.
Coorstek's three-year grant acceleration
CoorsTek, Inc. shows 2 grants in 2022–2024 against only 2 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.
