Previously, pharmaceuticals and tobacco products had to have registered trademarks before they could be sold on the market. After the revision of the Drug Law, there is no requirement for registered trademarks for drugs, and tobacco products must also have registered trademarks. Accordingly, now only tobacco product manufacturers must have registered trademarks, and there are no rigid regulations for other manufacturers. However, in today's market economy, it is unimaginable for products without trademarks. Whether registered or unregistered, as long as a large-scale enterprise has a trademark, it will have a trademark. Since the protection of unregistered trademarks in my country is very weak, and in order to prevent others from rushing to register, it is recommended that manufacturers either not use the trademark, or apply for registration at the same time or even before use. Only in this way can you protect your intellectual property rights.
