Evansville, Indiana – In the matter of Berry Plastics Corporation v. Intertape Polymer Corporation, Judge Richard L. Young of the Southern District of Indiana ruled on Defendant Intertape’s motion to reconsider the court’s conclusion of patent invalidity on the grounds of obviousness.
This Indiana patent litigation, filed in January 2010, sought a declaratory judgment of non-infringement of U.S. Patent No. 7,476,416 (the “‘416 patent”). Plaintiff Berry Plastics Corp. sued competitor Intertape Polymer Corp., which owns the ‘416 patent.
In the complaint, Berry asked the federal court to rule that it had not infringed the patent-in-suit, titled Process for Preparing Adhesive Using Planetary Extruder. In the alternative, it asked that the court rule that the patent was invalid and unenforceable. Among the reasons cited for this proposed conclusion were assertions that Intertape had engaged in improper conduct before the U.S. Patent and Trademark Office and that the patent was invalid as obvious.
The court held a jury trial in November 2014. The jury found, inter alia, that the ‘416 patent was not obvious. After the trial, the court heard additional argument on the issue of the validity of the patent and ruled for Berry, holding that the patent-in-suit was invalid as obvious.
In this recent entry, the court rules on Intertape’s motion to reconsider on the grounds that the court had ruled too broadly, inadvertently invalidating the entire patent instead of addressing only the asserted claims presented at trial. The court held that it was permitted under Fed. R. Civ. P. 54(b) to modify its previous order (“[A]ny order or other decision … that adjudicates fewer than all the claims …does not end the action as to any of the claims or parties and may be revised at any time before the entry of a judgment adjudicating all the claims …. “). It also concluded that, under Fed. R. Civ. P. 50, it had the authority to enter judgment against a party after a jury trial as long as “a reasonable jury would not have a legally sufficient evidentiary basis to find for the party on that issue.”
The court first held that certain dependent claims had not been challenged as invalid at trial and, consequently, the court had no jurisdiction to rule on the validity of those claims. On these claims, it granted the motion to reconsider.
Regarding those dependent claims that had been asserted at trial, the court evaluated the evidence and testimony presented and concluded that the dependent claims added no patentable subject matter but were instead simply obvious selections of prior art used in an ordinary way. Consequently, the court denied Intertape’s motion to reconsider.
