  • In China, the official fees are based on the application as published and it is therefore not possible to reduce claims fees by amending the claims at national stage entry. Any amendments made could incur additional translation costs.

  • Unlike most countries that require signed forms from the applicant, the Chinese Patent Office now accepts faxed or scanned color copies of documents.
