In the United Kingdom, trademarks are registered with the Intellectual Property Office (IPO) and protected under the Trade Marks Act 1994. The registration process typically takes around 3-4 months and requires proof of use in order to maintain the trademark. Trademark rights are based on registration rather than use, which means that even if a trademark has been used extensively but not registered, it may not be protected. The UK also allows for broader protection for “well-known” trademarks. In China, trademarks are registered with the China National Intellectual Property Administration (CNIPA) and protected under the Trademark Law of People’s Republic of China. China follows a “first-to-file” system, which means that whoever files a trademark application first generally has priority over others who may have used the mark before them. This makes it important to register a trademark as early as possible in China. The registration process can take up to 18 months and there is a high volume of trademark applications, which can make it difficult to secure a registration. Additionally, enforcement of trademark infringement can be challenging in China. In Brazil, trademarks are registered with the Brazilian Patent and Trademark Office (INPI) and protected under the Industrial Property Law. Like the UK, trademark rights are based on registration rather than use, but there is an exception for well-known trademarks. The registration process can take up to 36 months and requires proof of use after the first five years of registration. Enforcement of trademark infringement can also be challenging in Brazil. It is important to note that these are only brief overviews and there may be many specific nuances or differences in the trademark laws of each country.
