Any business and individual doing business can become your potential customers. But you have to carefully explore his needs. For example, if the company is newly established and has not yet registered a trademark, then it will be necessary to provide suggestions on basic registration protection. Larger companies should be advised to protect relevant product categories to avoid market confusion caused by the registration of related products by others. Especially large companies should be advised to register all categories to maintain a unified image of their brands. You can usually register more customers in the trademark announcement. If some companies or individuals rush to register the trademarks of some well-known companies on related product categories or products that may have an adverse impact on their brands, you should contact them in time to raise objections to the trademarks. You can find the list of customers whose trademarks have expired and need to be renewed on the trademark website or trademark search software and contact them. There are many ways to find customers, including phone calls, the Internet, sending letters, and door-to-door visits.
