Incorrect e-mail format?

When applying for a patent to the Patent Office, the format of the email address must be correct, otherwise the system will prompt that the email address is incorrect. The following is the correct format for filling in the mailbox:

E-mail addresses must contain the "@" symbol, such as example@qq.com, where there can be no spaces before and after the "@" symbol.

E-mail address cannot contain special characters, such as #, $,&,*,+,/,=,?. , {,|,}, ~, and so on.

You cannot have more than one "@" symbol in an email address.

The e-mail address must contain a top-level domain name, such as "". com“，”。 Cn "and". Net ".

If you use the correct email format, but still can't pass the system verification, please check whether you have entered the correct email address and password, and make sure that the email address is still valid. If the problem still exists, you can contact the customer service of the Patent Office for further help.
