First of all, design belongs to the category stipulated in the patent law. Paragraph 2 of Article 59 of China's Patent Law stipulates that the scope of protection of the design patent right shall be subject to the design of the product shown in the picture or photograph, and the design of the product shown in the picture or photograph may be explained by a brief description. Whether the design has applied for a patent requires specific inquiry. But I personally don't feel it. I feel that all brands of mobile phone glass are similar. We amateurs may not know the details. We only know that $4.5 is as big as $4.5, and $5.0 is as big as $5.0. As for the things on the screen, we can't see or understand them.

Secondly, as for the Logo you mentioned, it belongs to the category of trademark law. Article 52 of China's Trademark Law stipulates that any of the following acts is an infringement of the exclusive right to use a registered trademark:

(1) Using a trademark identical with or similar to its registered trademark on the same or similar goods without the permission of the trademark registrant;

(2) selling goods that infringe upon the exclusive right to use a registered trademark;

(3) Forging or unauthorized manufacturing of registered trademark marks of others or selling forged or unauthorized registered trademark marks;

(four) without the consent of the trademark registrant, the registered trademark is changed and the goods with the changed trademark are put on the market again;

(5) causing other damage to the exclusive right to use a registered trademark of others.

You produce a screen with the same appearance but no LOGO for mobile phone maintenance, which will not infringe trademark rights. I hope I can answer your questions and wish you a prosperous business!
