Indiana Patent Litigation: Four Mile Bay Asserts Patent Infringement Claims Against Zimmer


Hammond, Indiana – Patent attorneys for Four Mile Bay LLC (“FMB”) of Wadsworth, Ohio instituted intellectual property litigation in the Northern District of Indiana alleging that Zimmer Holdings, Inc. (“Zimmer”) of Warsaw, Indiana infringed its patented “Hip Implant With Porous Body,” Patent Nos. 8,821,582 and 8,506,642, which have been registered by the U.S. Patent Office.

Zimmer is a manufacturer and marketer of reconstructive orthopedic implants, including hip implants. At issue in this Indiana patent lawsuit are United States Patent Nos. 8,821,582 (the “‘582 patent”) and 8,506,642 (the “‘642 patent”). Zimmer is accused of having infringed and continuing to infringe the ‘582 and ‘642 patents by making, selling, and using hip implants, including a Trabecular Metal Primary Hip Prosthesis, that embody the patented invention.

Ownership of the ‘582 patent, issued for an invention in a method of machining, fabricating, and attaching components of a hip implant with a porous body, is claimed by FMB. FMB also asserts ownership of the ‘642 patent.

In this Indiana litigation, patent lawyers for FMB ask the court for the following:

  • Judgment that Zimmer has directly infringed claims of the ‘582 patent and the ‘642 patent;
  • For a reasonable royalty; and
  • For pre-judgment interest and post-judgment interest at the maximum rate allowed by law.

The case was assigned to Chief Judge Philip P. Simon and Magistrate Judge Christopher A. Nuechterlein in the Northern District of Indiana and assigned Case No. 3:15-cv-00063-PPS-CAN.
