according to the company law, as long as the font size is not a well-known trademark, you can use the same font size as others as long as the industry is different from others. Imagination is not a well-known trademark, so as long as your industry is not digital or similar, you can use the font name Imagination. For example, thinking about hardware, thinking about automation equipment, thinking about restaurants, thinking about technology, and so on, are all possible. If you go to the website of the Industrial and Commercial Bureau for font size query, just enter a font size to check it, and you will find that there are usually hundreds of companies or shops with the same font size but different industries. With so few Chinese characters and so many enterprises, it is inevitable to overlap.
moreover, when the industrial and commercial bureau (institute) applies for your license, it will first inquire about the font size you applied for. If it is not available, it will not be approved. Since it has been done for you, it will definitely be used. It is useless for others to sue you. At most, you can only sue the industrial and commercial bureau.
In addition, whether the name on the signboard of your shop is the same as the name on your license is not a problem. The signboard is only a means of marketing. As long as it is not suspected of malicious deception, it will be fine. There are so many shops on the street, and 9% of the signboards are not exactly the same as their license names.
