The maker of the Satisfyer Pro clit sucker devices has been told that its patent for the sex toy range is invalid in Australia, as the company lost a patent infringement case in the country.
German company EIS GmbH, which owns the Satisfyer Pro brand, claimed that Lelo Australia had infringed on its patent with its clitoral stimulator devices. However, a judge said that EIS GmbH’s patent was vague and lacked definition.
The Satisfyer Pro (pictured below) has proved popular since its launch in Australia in 2016, due to its contactless sucking function designed to pleasure the clit. Many other sextech brands have released clit-sucking sex toys over the past decade, including Lelo Australia, which is the Australian branch of Swedish sextech company Lelo.
EIS GmbH won a legal case in Germany in 2024, which resulted in some Lelo products being pulled from sale in the country. However, News.com.au reported that a judge ruled that the Satisfyer Pro patent was not sufficient for this to happen in Australia, and that EIS GmbH had acted like it had a “monopoly” on clit-sucking devices.
Justice Kylie Downes said: “The invention claimed in the patent is for a compression wave massager device which has particular features when used on the clitoris. The invention is not defined. [The patent] is therefore invalid and should be revoked.”
EIS GmbH’s claim against Lelo Australia was formally dismissed, with Lelo Australia granted legal costs.
One country at a time…
The German company had claimed to be a clit-sucking trailblazer, but in the Australian court retail experts explained that devices like these had been around before the Satisfyer Pro. The court heard that the Womanizer, for example, was released in Australia in 2015 and was popular from the start.
A sex toy retailer giving evidence in court said it was commonly known in the industry that sex toys using air pressure were introduced to the Australian market around 2014.
EIS GmbH had more success in 2024 in Germany, where it was ruled that the Lelo products Sona (Sona 2 Cruise pictured above), Sila and Enigma infringed on the Satisfyer Pro patent, and were required to be removed from sale.
In 2025 EIS GmbH tried to get the same three Lelo products banned from sale in Sweden, over the same patent infringement claim. A Swedish court ruled that the patent was not valid, so the Lelo products were not in violation of it.
