What this shows Harvey's Innovation Score is 33.4/100 (44th percentile 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 Harvey?

Each dot is one of Harvey’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). Harvey’s own 6.5 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Harvey's grants concentrate

Harvey Water Softeners Limited is a focused PatentsView assignee: 6 CPC subclasses with 53.8% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2019. By volume, Harvey sits between Haler US Appliance Solutions, Inc. and Heye International GmbH.

Harvey's three-year grant acceleration

Harvey Water Softeners Limited shows 7 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.
