International patents expert witnesses may opine on international patents and licensing, drug patents, patent prosecution, and patent infringement. The USPTO describes the Leahy-Smith America Invents Act (effective 3/16/13):
“Migration to a first-inventor-to-file system will bring greater transparency, objectivity, predictability, and simplicity to patentability determinations and is another step towards harmonizing U.S. patent law with that of other industrialized countries,” said Acting Under Secretary of Commerce for Intellectual Property and Acting Director of the USPTO Teresa Stanek Rea.
Prior to the passage of the AIA, the USPTO was the only national patent office using a “first-to-invent” system. First-inventor-to-file complements USPTO’s existing efforts toward greater harmonization with foreign counterparts. One result of these efforts is the Cooperative Patent Classification system launched on January 1st of this year, a common classification system that will enhance the examination capabilities of both the USPTO and the European Patent Office. Another such effort is USPTO’s ongoing coordination with the world’s largest patent offices–the so-called Tegernsee Group dialogues. The USPTO currently is seeking comment on these initiatives.
