John Heithaus specializes in drafting and prosecuting patent applications in the areas of biotechnology, oil and gas, biochemistry and pharmaceuticals. He has filed multiple appeal briefs before the PTAB and participated as counsel in litigation matters in the United States. Mr. Heithaus previously worked at a leading biological and chemistry firm in Osaka, Japan. In Osaka, he advised international clients as to Japanese prosecution and litigation.

Prior to entering the patent field, Mr. Heithaus worked in the protein engineering laboratory of Anthony Kossiakoff for over four years at the University of Chicago. During his research, Mr. Heithaus engineered by directed mutagenesis entropy minimized variants of hGHBP, optimized surface plasmon resonance and expression protocols for hGH, and, via phage display, engineered conformation specific antibodies to rescue protein function. His thesis “In vivo active conformation specific phage display” led to the publication “Allosteric control of ligand-binding affinity using engineered conformation specific effector proteins” in Nature Structural and Molecular Biology.
