Does more volume mean deeper claims for Chandler?

Each dot is one of Chandler’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). Chandler’s own 25.9 claims/patent is ABOVE the 18.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chandler's grants concentrate

Chandler Systems, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 91.7% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2015. By volume, Chandler sits between Biofire Technologies Inc. and Clarifai, Inc..

Chandler's three-year grant acceleration

Chandler Systems, Inc. shows 8 grants in 2022–2024 against only 19 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.
