A federal judge in Maine denied a company’s motion to dismiss a patent infringement suit filed against it, concluding a letter the patent holder sent the alleged infringing company plausibly established the defendant’s specific intent to encourage customer infringement.

U.S. District Judge Lance E. Walker for the District of Maine denied Rejuva Fresh and its owner Polly Jacobs’ motion to dismiss a patent-infringement suit over electromagnetic technology in noninvasive aesthetic body-contouring devices, brought by BTL Industries Inc., after it determined that defendants plausibly knowingly infringe on BTL’s patents.
