Patent and Trademark Office August 10, 2007 – Federal Register Recent Federal Regulation Documents

The United States Patent and Trademark Office (Office) is proposing to revise the rules of practice pertaining to any claim using alternative language to claim one or more species. The search and examination of such claims often consume a disproportionate amount of Office resources as compared to other types of claims, because determining the patentability of these claims often requires a separate examination of each of the alternatives within the claims. The Office expects that requiring applicants who choose to draft claims that read on multiple species using alternative language to maintain a certain degree of relatedness among the alternatives will enable the Office to do a more thorough and more reliable examination of such claims.
