USPTO PatentsView assignee record - 92 granted patents across 49 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING).
The verdict
Watts holds 92 US patents across 49 technology areas, rank #3,950 of 50,000 tracked assignees.
Watts Regulator Co. has been granted 92 US utility patents between 2017 and 2025, placing Watts Regulator Co. at rank #3,950 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING). As a US Corporation, Watts Regulator Co. is one of the more focused assignees in the PatentsView dataset. By volume, Watts sits between Tsann Kuen (zhangzhou) Enterprise Co., Ltd. (92 patents, rank #3,946) and Anhui Huami Information Technology Co., Ltd. (91 patents, rank #3,954) - the closest US assignees by grant volume. The composite Innovation Score of 69.2/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 80 grants, compared with 12 in the 2015–2019 window, a +567% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Watts Regulator Co.'s 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Watts Regulator Co. against peers pursuing similar technology classes.

How to use this portfolio
Watts's 92 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
