The regulations, which addressed the number of continuation applications as well as the number of claims that could be included within each application, were published in the Federal Register in August 2007, but were enjoined and never came into effect.
The USPTO also announced that it will file a motion to dismiss and vacate the federal district-court decision in a lawsuit filed against the USPTO that sought to prevent the rules from taking effect.  GlaxoSmithKline - one of two plaintiffs in the Tafas v. Kappos lawsuit - will join the USPTO’s motion for dismissal and vacatur.
 “The USPTO should incentivize innovation, develop rules that are responsive to its applicants’ needs and help bring their products and services to market,” Kappos said. “These regulations have been highly unpopular from the outset and were not well received by the applicant community. In taking the actions we are announcing today, we hope to engage the applicant community more effectively on improvements that will help make the USPTO more efficient, responsive, and transparent to the public.”
 “We are grateful to GlaxoSmithKline for working with us to file this joint motion to both dismiss the appeal and vacate the district court’s decision. This course of action represents the most efficient way to formally and permanently move on from these regulations and work with the IP community on new ways to take on the challenges these regulations were originally designed to address.”
