What this shows Johnson's Innovation Score is 58.2/100 (top 5% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Johnson?

Each dot is one of Johnson’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). Johnson’s own 16.6 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

How Johnson's grant cadence moved

Between 2020–2024, Johnson Matthey PLC received 7 grants versus 67 in 2015–2019 (-90% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 26 grants and bottomed in 2024 at 1. Lead class B01J accounts for 55.4% of the portfolio across 52 subclasses. Volume neighbours: Huntsman Petrochemical LLC (#4,719) and Magnolia Medical Technologies, Inc. (#4,727).

Johnson's three-year grant acceleration

Johnson Matthey PLC shows 5 grants in 2022–2024 against only 4 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.
