(Northern California Record) Nevro Corp., a global medical device company based in Redwood City, California, has announced it is facing a lawsuit from Boston Scientific. 

The plaintiff alleges patent infringement against Nevro, which provides evidence based solutions for the treatment of chronic pain. The case was filed Dec.9, 2016, in U.S. District Court for the District of Delaware. 

In the lawsuit, Boston Scientific says Nevro is infringing on the plaintiff's patents, which cover technology related to stimulation leads, batteries, and telemetry units. This suit comes after a previous action filed by Nevro Corp against Boston Scientific Nov. 28, 2016. In the previous lawsuit, Nevro alleged Boston Scientific infringed on Nevro's patents covering the Senza system and HF10 therapy.

The patents related in the first lawsuit involved Senza and HF10 spinal cord stimulation system. The Senza system, which is designed to deliver up to 10,000Hz to the spinal cord of patients in order to avoid a tingling sensation known as parasthesia, won pre market approval by the FDA in May.

One of the patents related to the November 2016 lawsuit against Boston Scientific by Nevro Corp. was U.S. patent No. 8,359,102, which is for selective high-frequency spinal cord modulation. The Patent Trial and Appeals Board of the U.S. Patent and Trademark Office declined an inter partes review Nov. 30, 2015, after finding out Boston Scientific had failed to establish a reasonable likelihood of showing that previous challenged claims of Boston Scientific toward the patent were invalid.
