Does more volume mean deeper claims for Pittsburgh?

Each dot is one of Pittsburgh’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). Pittsburgh’s own 24.7 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Pittsburgh's grants concentrate

Pittsburgh Glass Works, LLC is a focused PatentsView assignee: 14 CPC subclasses with 52.4% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Pittsburgh sits between Phibro Animal Health Corporation and Poseida Therapeutics, Inc..

Pittsburgh's three-year grant acceleration

Pittsburgh Glass Works, LLC shows 6 grants in 2022–2024 against only 6 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.
