The patent battle between Shenzhenshi Leiming Shangmaozhongxin and Novoluto GmbH puts patent US9763851B2 under scrutiny. This patent claims a groundbreaking stimulation device designed for erogenous zones, offering a pressure-based experience without direct skin contact.
Marketed as an innovation that reduces irritation and enhances hygiene, this technology has been a key player in its industry. But does it truly stand on new ground, or is there prior art that could shake its foundation? If earlier patents disclose similar pressure-based stimulation mechanisms, Novoluto’s claims could be at risk.
That is where Global Patent Search (GPS) comes in, helping uncover potential prior art that could challenge the validity of US9763851B2. Let us break down this patent’s core features before diving into the prior art that could put it to the test.
Understanding Patent US9763851B2
Patent US9763851B2, owned by Novoluto GmbH, describes a stimulation device for erogenous zones, specifically designed to create a pressure field that stimulates the clitoris without direct contact.
Unlike traditional vibratory stimulators, which rely on direct skin contact, this device uses alternating pressure waves to generate a massage-like effect, enhancing pleasure while reducing skin irritation and hygiene concerns.
Source: US9763851B2
Its four key features are:
#1. Pressure field generator – Uses at least two chambers to create alternating positive and negative pressures, simulating natural stimulation.
#2. Connection element – Links the two chambers, directing airflow to the erogenous zone without direct touch.
#3. Drive unit & control device – Controls the pressure field’s intensity and pattern, allowing for customizable stimulation.
#4. Hygienic, non-contact stimulation – Reduces the risk of irritation, habituation effects, and hygiene concerns found in traditional suction-based stimulators.
Novoluto GmbH’s US9763851B2 is at the center of litigation, with Shenzhenshi Leiming Shangmaozhongxin potentially challenging its validity. If prior patents disclose similar pressure-based stimulation technology, Novoluto’s claims could face scrutiny. Finding strong prior art could impact this case significantly.
