Pre-entry review
PCT National Phase Entry in China
Enter the China national phase with examiner-style claim strategy.
Ma Su Team helps overseas applicants and foreign patent firms review PCT applications before China national phase entry, identify claim support and inventive-step risks, and prepare a prosecution route that fits Chinese examination practice.
Why It Matters
China national phase entry should not be treated as a purely formal deadline.
A PCT application may be technically strong, but China prosecution still depends on claim support, technical contribution, prior-art feature comparison, amendment restrictions, and how the claim hierarchy is positioned. Reviewing these issues before entry helps reduce avoidable office actions and preserve useful commercial scope.
