What this shows Johnson's Innovation Score is 45.1/100 (top 24% 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 13.0 claims/patent is ABOVE the 4.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Johnson's grants concentrate

Johnson Matthey Hydrogen Technologies Limited is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2022. By volume, Johnson sits between Jiangsu Comco Outdoor Products Co., Ltd. and K Sciences GP, LLC.

Johnson's three-year grant acceleration

Johnson Matthey Hydrogen Technologies Limited shows 4 grants in 2022–2024 against only 0 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.
