Technology Highlights

• Male-female protrusion/aperture connections between basin and drain anchor the drain during installation, improving reliability over conventional friction-fit drains.
• Claims reach electric, water-pressure, and air-pressure activation of switch-controlled stoppers and valves — broad coverage across multiple real-world implementation approaches.
• A quarter-turn ball valve provides an alternative flow-control mechanism at the drain, alongside stopper and strainer modules.
• An April 2007 priority date predates the current wave of smart-home, IoT-enabled water-control products by roughly a decade.
• Both patents are already issued, with best term running to October 18, 2030 — no pending prosecution before a buyer can act.
