duPont v. Medtronic


Oral Argument
09/18/13 – 09/18/13


In this oral argument before the Delaware Supreme Court, the attorney representing Du Pont appealed the decision of the lower court, which held that the stent portion of a stent delivery system is not part of a "catheter". This is a royalty dispute between Medtronic and DuPont involving a 1989 patent assignment and cooperative research agreement (“PACRA”) originally entered into by DuPont and C.R. Bard, In. This dispute is about the royalties that Medtronic was obligated to pay on certain “catheters” -- stent systems used in coronary angioplasty that included balloons covered by the Levy patents.


The judgment of the Superior Court was affirmed.
