Contribution
Claim Drafting and Reconstruction for China
Rebuild claims around technical contribution, support, and China examination logic.
Ma Su Team helps overseas applicants and foreign patent firms review, draft, and reconstruct patent claims for China filing, PCT national phase entry, office action response, FTO-driven design-around, and portfolio planning.
Claim Strategy
Good China claims need both technical precision and amendment room.
Claim drafting for China should clarify the real technical contribution, avoid unsupported overbreadth, preserve fallback layers, and explain technical effects in a way that can survive examination. Claim reconstruction is especially useful when the original foreign filing was not drafted with Chinese prosecution in mind.
