1. The incompleteness and lag in retrieval of online trademark information databases can lead to misjudgments of trademark registration risks, thereby underestimating the risks of registration. Since various trademark applications require a certain period of time from the date they are received by the Trademark Office until they can be retrieved from the computer database, the blind spot for external inquiries is generally 3 to 6 months. Although the time within the Trademark Office is slightly shorter, it cannot be avoided.

2. Limitations of information sources. Since place names, prior rights, industry information, product information, etc. will all affect trademark registration, even if the risk cannot be found in the trademark data, it does not mean that there is no risk in trademark registration.

3. Changes in government review standards will also cause authorization risks. For example, trademark-related laws, regulations and policies will be dynamically adjusted with the development of the market economy and new issues. Such adjustments will inevitably affect the review standards.

4. The risk of subjectivity in the review scale of the examiner. Due to differences in personal understanding, different examiners and different categories of examiners may reach completely opposite judgment results, and the law also gives examiners the discretion to exercise based on personal understanding during the examination process, so this is also Increased uncontrollability of registration risks.
