Engin Ozkaynak 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).

  • Patent number: 5344654
    Abstract: A prosthetic device comprising a prosthesis coated with substantially pure osteogenic protein is disclosed. A method for biologically fixing prosthetic devices in vivo is also disclosed. In this method, a prosthesis is implanted in an individual in contact with a substantially pure osteogenic protein, enhancing the strength of the bond between the prosthesis and the existing bone at the joining site.
    Type: Grant

  • Patent number: 5266683
    Abstract: Disclosed are (1) osteogenic devices comprising a matrix containing substantially pure natural-sourced mammalian osteogenic protein; (2) DNA and amino acid sequences for novel polypeptide chains useful as subunits of dimeric osteogenic proteins; (3) vectors carrying sequences encoding these novel polypeptide chains and host cells transfected with these vectors; (4) methods of producing these polypeptide chains using recombinant DNA technology; (5) antibodies specific for these novel polypeptide chains; (6) osteogenic devices comprising these recombinantly produced proteins in association with an appropriate carrier matrix; and (7) methods of using the osteogenic devices to mimic the natural course of endochondral bone formation in mammals.
