The U.S. Patent Trial and Appeal Board (PTAB) determined it would not take an inter partes review petitioned by Advanced Bionics Inc., in a patent dispute with Med-El Elektromedizinische. The precedential PTAB decision notes that it had invoked a two-step process for declining to take the petition as seen in a patent dispute involving Becton Dickinson and Co., and affirming that this will be the standard for addressing prior art in such appeals going forward.
