Patents by Inventor Robert L. Merker

Robert L. Merker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Biostatic product using interpenetrating network polymers
    Patent number: 6572926
    Abstract: Applicants' invention is a product that is biocompatible and antimicrobial. According to Applicants' invention, a monomeric quaternary ammonium salt in a solvent is exposed to a polymeric substrate. The quaternary salt in solvent is absorbed by the polymeric substrate and the quaternary salt is polymerized thereby creating a product having quaternary salts impregnated on its surface. The polymerized material also penetrates the surface to some depth forming an interpenetrating network.
    Type: Grant

  • Method of creating a biostatic agent using interpenetrating network polymers
    Patent number: 6146688
    Abstract: Applicants' invention is a method for creating an interpenetrating network on the surface of devices and supplies that is biocompatible and antimicrobial. According to Applicants' invention, a polymerizable or monomeric quaternary ammonium salt in a solvent is exposed to a polymeric substrate. The quaternary salt in solvent is absorbed by the polymeric substrate and the quaternary salt is polymerized such that an interpenetrating network is formed with said polymeric substrate.
