There are three kinds of patents: invention, utility model and design. The main difference is that the technical content of the concept is different, the length of protection is different, and the maintenance cost is different.
To apply for a patent, you only need to submit the application documents and related fees to the Patent Office in accordance with the types and formats of documents specified by the Patent Office. The patent office will give you an application number to prove your application. Then review the format of your application documents, put forward all kinds of discrepancies, modify them by you, and publish them by the patent office after passing.
After the publication of utility models and designs, patent certificates may be granted. A patent certificate can only be granted to you after the invention patent has passed the substantive examination within three years.
Judging from the above procedures, it is easy to apply for a patent for utility model and design, as long as you submit the application documents and pay the fee. However, if someone suggests to the Patent Office that your idea is not unique and cannot be copied and applied before the filing date, your patent may be revoked, and all previous efforts, money and patent profit expectations will be wasted. The content of the invention patent will be examined before it is granted, and the certificate can only be issued after it has passed the examination. Therefore, the application time for invention patents is longer, but it is more secure.
There are prescribed requirements and skills for writing patent application documents. It is suggested that you carefully study the patent law, implementation rules and review guidelines before writing, or entrust a qualified agency directly.
