Our National Phase Entry and Prosecution Process

Attorneys at the Firm enter and prosecute the United States national phase portion of Patent Cooperation Treaty (PCT) and Paris Convention patent applications for patent owners and law firms around the world. Before filing a United States national phase application, the Firm’s attorneys conduct a thorough review of the application and the business objectives. Attorneys at the Firm provide guidance and advice regarding claim strategy and the intricacies of United States law throughout prosecution.

Declaratory and Experimental Evidence

The United States makes extensive use of declaratory and experimental evidence. Declarations must be written to not only overcome the examiners’ rejections, but must also be written to withstand potential challenges from litigation counsel, the Patent Trial and Appeals Board (PTAB), the Federal Circuit and more experienced personnel in the USPTO reexamination division.

The United States Patent Office is quite rigorous in defining the proper experimental protocol to demonstrate an improvement or a synergistic result. Failure to follow this protocol can result in the patent failing to withstand challenges by the examiner, experts, litigation counsel, the PTAB, the Federal Circuit and more experienced personnel in the USPTO reexamination division.

The Firm’s attorneys have industrial and laboratory experience prior to becoming attorneys. These attorneys provide significant expertise in recommending the proper experimental protocol for declarations. The Firm also has a long history of experience with experts in a variety of fields who can provide objective third party evidence in patent cases.

The Examiner Interview

An Examiner Interview is an exceptionally effective way to overcome difficult rejections. The Firm does not charge for travel time and expenses to attend an Examiner Interview.
