CadioNet sought to sever the patents that were found to be directed to ineligible subject matter from the remainder of the case, which remains to go to trial, so that the ruling on the two patents could be immediately appealed. Judge Talwani determined that, given the posture of the case, Fed. R. Civ. P. 54(b) should apply, rather than Rule 21 as had been argued by CardioNet. Noting the “long-settled and prudential policy against the scattershot disposition of litigation,” Judge Talwani determined that CardioNet’s decision to bring all four patent claims in a single action, “presumably based on its view that the claims are related and involve common sets of fact and law,” mitigate against entry of separate judgment on the two invalidated patents. She did note that CardioNet had a different pair of related patents that were invalidated on Alice grounds at the District Court level (also by Judge Talwani), and that she would likely have granted severance if CardioNet had sought it at the time the appeal on those patents was filed; but as the appeal in that case has been fully briefed, severing the claims in the current case would result in three different litigation tracks. Accordingly, CardioNet’s motion to sever was denied.
