American patent applications are divided into three categories?

1, patent for utility model, American patent law stipulates that all inventions or discoveries of novel and practical methods, machines, products and components of substances, or new uses of known substances, or further improvement of existing technologies, are objects protected by American patent law, and the protection period is 20 years from the date of filing. It is equivalent to our invention patent application in China.

2. Design patents Design patents protect new, original and decorative designs of products. The protection period is fourteen years from the date of registration.

3. Plant patents. Plant patents protect new and unique new plant varieties that are reproduced asexually or sexually. The term of protection is 20 years from the date of application.

In addition, we often hear the concepts of temporary application and non-temporary application. These two applications are only suitable for practical applications and factory applications.

4. The temporary application must be converted into a formal application within one year: only the specification and drawings are submitted, and it must be converted into a formal patent application within one year, or a new formal application is filed with the priority of the temporary application. Enjoy the filing date of the temporary application. Note: In the United States, there is no patent protection for new inventions.
