Patent Filing Routes in China
In order to get a patent in China, there are 3 routes:

- This route allows you to file a patent application with the Chinese National Intellectual Property Administration (CNIPA).
- If granted, the patent shall be valid in China only.
2. International Filing via Patent Cooperation Treaty (PCT)
- The PCT route allows you to file a single patent application simultaneously in a number of countries.
- PCT has 152 Contracting States and is administered by the World Intellectual Property Organisation (WIPO).
- The granting of a patent in China remains under the control of the CNIPA, i.e “national phase”.
3. International Filing via Paris Convention
- Similar to the PCT, the Paris Convention allows simultaneous multi-country filing.
- Paris Convention has 177 Contracting States and is also administered by WIPO.
- The granting of a patent in China remains under the control of the CNIPA.
