According to the current situation, on average, each country needs to pay 4000 ~ 5000 dollars to apply for a patent, and if it is calculated by five countries, it needs to prepare about 20 thousand ~ 25 thousand dollars; We also have to pay the fees for the international phase of PCT, including the transmission fee, retrieval fee and international preliminary examination fee of about 265,438+000 yuan charged by China Patent Office, and the basic fee, designation fee and handling fee of about 65,438+065,438+050 yuan charged by the International Bureau.
I also introduced the way of international patent application to you. If it is an international application filed by an individual from China; The fees charged by the International Bureau can be reduced by 75%. When the applicant wants an invention to be protected by more than five countries (generally more than five countries), it is appropriate to use the PCT approach. Because only one international application needs to be submitted to the Chinese Patent Office through PCT, the trouble of submitting national applications to each country is avoided. When the applicant only needs to apply for a patent in one country or several countries, it is appropriate to use the Paris Convention.
It can be seen that if you want to apply for an international patent, you need to spend a lot of money, but if you apply, you can get international protection, so the money is worth it. Of course, if you want to entrust an agency to help you apply, you will be relieved.
