Patent Prosecution: Tafas v. Doll INTELLECTUAL PROPERTY

United States Patent Office Publishes New Rules on Continuing Applications and Claims

On August 21, 2007, the US Patent and Trademark Office published revised rules that make a number of controversial revisions relating to patent prosecution. Two key aspects of the revised rules involve limitations on the number of continuation applications and the number of claims in an application. In particular, the revised rules provide that an applicant seeking to file more than two continuation or continuation-in-part applications, or more than one request for continued examination, must present a showing as to why an amendment, argument or evidence sought to be entered could not have been previously submitted. The revised rules also require an applicant to file an examination support document covering all of the claims in any application containing more than five independent claims or 25 total claims. Revised rules also were published regarding multiple applications having the same filing or priority date, substantial overlapping disclosure, a common inventor and common ownership.
