First, first determine whether the trademark dispute is true, or the deception of a liar, or the sales trick of a salesman? Many enterprises have encountered some nonexistent trademark disputes, and then fiddled around for a long time, only to find that the disputes did not exist from the beginning. Second, determine which trademark is controversial? What kind of controversy is the trademark? Third, judge the impact of the dispute on the enterprise itself. Fourth, consult professionals, such as lawyers and trademark professionals, to seek solutions. The earlier the dispute appears, the better. The longer the delay, the greater the negative impact on the enterprise.
