Cardinal Files Lawsuit Against Oldcastle

Cardinal IG filed a lawsuit last week in the US District Court in Minnesota alleging Oldcastle Glass infringed upon six of its patents.

The suit filed says that Cardinal acquired three of the patents listed in the initial complaint, and developed the rest internally. The suit further goes on to say Cardinal bought "Method of Producing Masked Glazing Panels," and "Masked Glazing Panels" from Oregon Glass Company in January 2003. It acquired "Method to Protect Glass in Doors and Windows from Scratches, Abrasion, and Painting Processes," from William B. Swensen in 1999. It developed "Methods and Devices for Manufacturing Insulating Glass Units," "Masking Method Using Lasers" and "Masking Glass Shapes."

Cardinal is petitioning the court that, "Oldcastle, its officers, agents, servants and employees, and those persons in active concert or participation with any of them be enjoined from further infringement of the Cardinal patents; An accounting be had for the profits and damages arising out of Oldcastle's infringement of the Cardinal Patents; Cardinal be awarded compensatory and exemplary damages, including treble damages for willful infringement as provided by 35 U.S.C § 284, with interest, but no less than a reasonable royalty; Oldcastle be preliminary and permanently enjoined from continued use and manufacture, sale, or offer for sale of Oldcastle's products that infringe the Cardinal patents; Cardinal be awarded its attorneys' fee, costs, and expenses in this action; Cardinal be awarded pre-judgment and post-judgment interest on its damages, as allowed by law; and Cardinal be awarded such other relief as this Court may deem just, equitable, and proper."

Neither side could be reached for comment as yet.
