PTAB Trials and Interferences

Richard Neifeld, Patent Attorney
703.415.0012 ext. 100

Both Dr. Hahl and I have substantial experience in inter partes Board practice, having collectively participated to various degrees on over 50 interferences during the last 20 years. After several years of interference practice, I was appointed to the chair of the AIPLA Interference Committee and served in that position for the 2000-2002 term. I also moderate the popular 'PatentInterPartes' forum in which many of the regular PTAB practitioners participate. In addition, I regularly publish articles on intellectual property, particularly patent law and PTAB practice. Assuming no conflict, if you need either strategic advice or immediate representation, we can help.
