In a long-running patent dispute concerning cardiac monitors, Judge Talwani denied in part CardioNet’s motion for summary judgment. CardioNet sought judgment that InfoBionic infringed four claims of one of the remaining patents, and that those claims, along with a claim from another of the remaining patents, were valid. Judge Talwani found, in a very short electronic order, that there were genuine issues of material fact with respect to validity and infringement on the four claims and denied the motion. With respect to the second patent, Judge Talwani set the validity for a February hearing. She further instructed CardioNet to address why summary judgment of non-infringement should not be granted on the basis that the accused MoMe system lacks a frequency domain T wave filter as that term was construed.
