How do I protect my patent in China?
If you have a US patent, you can convert it into a PCT application by entering the international stage with WIPO. You can then file your international application at the national stage with the China Patent Office.
How long does a Chinese patent take?
The average time for a Chinese patent to go from filing to issuance is 3 years.
Should I get a patent in China?
China is one of the most populated countries in the world. If you plan to do business outside of the US, there are 3 big reasons why you should consider getting a patent in China:
- it is a huge market of potential buyers for your invention;
- China is a popular location for outsourced manufacturing, and a patent would protect against manufacturer IP theft;
- China has a large number of online IP infringers and knock-off sellers that a patent would help protect against.
What is the new patent law in China?
China updated its patent laws in 2020 by adding the option to patent partial designs via design patents. China also extended the design patent term from 10 years to 15 years.
What is the 15 day patent rule in China?
The China Patent Office previously allowed a 15-day grace period for patent application responsive deadlines. However, as of January 20, 2024, that 15-day grace period has been revoked.
Are US patents enforceable in China?
Generally, no patent is enforceable against infringers in countries other than the issuing country. However, China is a member of the Patent Cooperation Treaty (PCT). The PCT provides applicants in participating countries to file expedited applications in other member countries. Thus, the holder of a US patent may take the patent to the international stage through the PCT and then file with the CNIPA.
