Multilayer Stretch Cling Film Holdings, Inc. v. Inteplast Group, Ltd. and AmTopp Corp.

Case Summary: 12-cv-2107

This is a patent infringement case relating to stretch wrap. There is a complicated history to this patent which includes alleged fraudulent transfers, undisclosed interfamily involvement, disputes between the two inventors over who invented what and when, and previous litigation.

The plaintiff claims to own a patent for a Multilayer Stretch Cling Film ("055 Patent"). Defendants, Inteplast Groups and AmTopp Corp., are in the business of designing, manufacturing, and selling flexible packaging films. MSCFH claims Inteplast’s stretch film products of seven or more layers infringe upon its patent.

Defendants claim that they are not infringing any valid or enforceable claim of the '055 Patent. They further allege and counterclaim that the patent is invalid and/or unenforceable for many reasons, including numerous claims of inequitable conduct and/or fraud by the patent holders in the prosecution of the patent before the Patent and Trade Office.

Defendants also claim that a decision in a previous case in which the court granted partial summary judgment of non-infringement of this patent applies to and resolves a number of issues in this case. Related to that, Defendants allege that MSCFH is a shell holding company controlled by Manuli USA, that was created for the purpose of shielding Manuli from possible exposure to judgments rendered against MSCFH in this and related litigation and/or to provide a layer of separation between MSCFH and admissions made by Manuli in previous litigation.

Four cases in which MSCFH is the plaintiff have been consolidated for the Claim Construction Hearing (aka Markman Hearing) held on January 25, 2013, which is the subject of the video. The matter was taken under advisement. Also pending is a Motion for Partial Summary Judgment filed by AmTopp and Inteplast.
