What is the pct patent?

Pct patent is the abbreviation of PatentCooperationTreaty. As can be seen from its name, the Patent Cooperation Treaty is an international cooperation treaty in the patent field.

Since the adoption of the Paris Convention, it has been regarded as the most important symbol of the progress of international cooperation in this field. However, it mainly involves the coordination and rationality of filing, retrieval and examination of patent applications and the dissemination of technical information contained therein.

PCT does not grant "international patents": the task and responsibility of granting patents can still only be undertaken by patent offices of various countries seeking patent protection or institutions exercising their functions and powers. PCT and Paris Convention are not competitive, but actually complementary. In fact, this is a special agreement under the Paris Convention, which is only open to the member countries of the Paris Convention.
