Whether the trademark right is acquired from the date of announcement by the Trademark Office or the expiration date of the announcement.

The trademark right will be obtained from the expiration of the announcement period.

An unregistered trademark is not called a registered trademark, and of course there is no "trademark right" if it is not registered.

If you use a font size, you will have the "right to the font size" from the date of registration and establishment of the font size.

Font size and trademark are not managed by the same management department.

Using a font size and owning the font size rights does not necessarily mean you have trademark rights, and vice versa.
