Wisdom & IP Strategy
Focus: The strategic and financial impacts of choosing PCT National Stage Entry (35 U.S.C. 371) versus a U.S. Bypass Continuation, the "Unity of Invention" standard, and the specific challenges for Taiwanese applicants. Taiwan Applicant Eligibility: Taiwan is not a member of the Patent Cooperation Treaty (PCT). Consequently, Taiwanese applicants cannot directly file PCT applications and generally need to utilize an "applicant of convenience" (such as a co-applicant or assignee from a PCT member state) to secure international filing dates. Box 371 vs. Bypass Continuation: Entering the U.S. National Stage under 35 U.S.C. 371 (checking "Box 371") subjects the application to the PCT "Unity of Invention" standard, which strictly requires inventions to be linked by a "single general inventive concept" featuring "special technical features" . In contrast, a bypass continuation is examined under standard U.S. restriction practice. Strategic Impact: The stricter PCT Unity of Invention standard limits prosecution flexibility and can lead to heavy divisional filing costs. Understanding the nuances between a 371 national entry and a bypass continuation is crucial for managing global patent prosecution budgets and avoiding forced separation of related claims.
