My practice focuses on intellectual property law, particularly patent law. I work in all areas of patent law, including preparation, prosecution, counseling, opinions, litigation, and post-issuance practice. Post-issuance practice is an important part of my work. This includes reissue applications, ex parte reexaminations, inter partes review, and interferences. I have taught CLE programs, spoken, and published on the strategic use of reexamination procedures. In our representation of clients, I have successfully used reexamination to overturn adversaries' patents. In the reissue area, client's patents have been successfully corrected by overcoming prior art and/or broadening to cover competitors' activities. I have worked on over declared 20 interferences in my career and have in many more instances been involved in counseling clients on potential interferences and preparing for interferences so that our clients are put in a position to prevail. With the passage of the American Invents Act, the post-issuance patent practice will become even more important, because this law expands such procedures for correcting or challenging patents to include post-grant oppositions, inter partes reviews, pre-issuance submissions, derivation proceedings, and supplemental examinations. To prepare for the availability of these procedures, I have extensively spoken on the procedures and advised clients on their strategic use. My clientele includes established companies, start-up companies, and universities. The technologies I work in include biotechnology, pharmaceuticals, chemistry, medical devices, chemical processing equipment, and mechanical devices generally. In the biotechnology area, I have worked on vaccines, recombinant production of proteins, personalized medicine, arrays, DNA amplification technology, DNA detection procedures, antigen detection, transgenic plants, stem cells, and screening small molecules against protein or nucleic acid targets.
