The Patent Cooperation Treaty (PCT) is the heart of the international patent system and should be considered in every applicant's patent filing strategy. When it is used appropriately, the PCT is a cost-effective option for international patent protection that provides benefits for applicants, patent offices, and third parties. But the PCT is also complex and challenging. 

Based on the authors' years of experience and the important lessons they have learned, this updated edition demystifies the PCT to help practitioners employ the system to their clients' advantage. Starting with an explanation of the PCT's framework and covering detailed information about procedures, safeguards, and strategy, the book's comprehensive chapters provide the necessary tools to effectively understand and use this global system.
