How Progress's grant cadence moved

Between 2020–2024, Progress Rail Services Corporation received 27 grants versus 44 in 2015–2019 (-39% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2015 at 15 grants and bottomed in 2020 at 3. Lead class B61L accounts for 37.3% of the portfolio across 51 subclasses. Volume neighbours: Pensando Systems Inc. (#4,679) and Shoei Co., Ltd. (#4,687).

Progress's three-year grant acceleration

Progress Rail Services Corporation shows 20 grants in 2022–2024 against only 12 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.
