Is it necessary to apply for pct patent? Are invention patents and utility model patents guaranteed?

Suggest whether to apply for PCT as needed.

It should be noted that patents are regional, and patent protection will be obtained in which country to apply for patents. If you don't apply for a patent in the corresponding country, you can't get patent protection.

Generally speaking, the main reason for applying for PCT is that the corresponding products need internationalization and need or are ready to enter the international market. In order to avoid disputes and protect yourself, there is no need to apply for PCT if you do not intend to enter the international market (because the cost of applying for PCT is still relatively high).

As mentioned above, patents are regional and are examined by the patent examination departments of the corresponding countries. Domestic patent applications are examined by the Patent Office in China National Intellectual Property Administration, China, and whether to apply for PCT has nothing to do with domestic examination and is not affected.

In a word, PCT application is not necessarily related to domestic patent application and patent examination, and the cost is high, so it should be decided carefully according to the needs.
