    Attacking a Patent at the PTO: Beware the Real Party in Interest

    by Eugene Perez | Corporate Counsel

    Patents are critical to the success of many companies, where having a good patent portfolio can protect commercial products, keep competitors out of the market and force licensing negotiations. Given the amount of patent litigation, with the latest patent reform laws of 2011, Congress has created new ways to attack and defend patents at the Patent Trial and Appeal Board (PTAB) of the U.S. Patent & Trademark Office (PTO) instead of district court or the International Trade Commission. The idea was to create an alternative forum for contesting patent validity and to reduce the amount of patent litigation. However, around 80 percent of PTAB procedures have concurrent litigation, though sometimes a stay in the litigation is possible. These PTO procedures are called post-grant review (PGR), inter partes review (IPR) and a PGR solely for business method patents (CBM), with IPR being by far the most popular.
