BTL Files Patent Infringement Lawsuit Against WonderFace Device

BTL Group has filed a patent infringement claim before the Unified Patent Court against Lexter Microelectronic Engineering Systems S.L., the company behind the WonderFace device.

The claim centers on BTL’s proprietary technology used in its EMFACE system, which integrates selective muscle stimulation and radiofrequency heating through hands-free applicators. The company alleges that the WonderFace device infringes on these patented innovations.

"We will vigorously defend our intellectual property to protect the investments of our clients. This lawsuit marks the beginning of our broader effort to take legal action against any third party that we believe infringes upon our innovations," said Tomas Schwarz, CEO of the BTL Enterprise Group.

According to BTL, the legal filing seeks to restrict the distribution of WonderFace devices across multiple European markets. A favorable ruling would be enforceable across 18 jurisdictions under the Unified Patent Court system.
