What this shows Watts's Innovation Score is 69.2/100 (top 1% 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 Watts?

Each dot is one of Watts’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). Watts’s own 14.6 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Watts's grants concentrate

Watts Regulator Co. is a focused PatentsView assignee: 49 CPC subclasses with 39.1% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2023 (21 grants) versus a trough of 2 in 2021. By volume, Watts sits between Tsann Kuen (Zhangzhou) Enterprise Co., Ltd. and Anhui Huami Information Technology Co., Ltd..

Watts's three-year grant acceleration

Watts Regulator Co. shows 50 grants in 2022–2024 against only 15 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.
