As for the reasons why the trademark registration process has slowed down, there may be many factors. The following are some possible reasons:

1. Impact of the epidemic: The global epidemic may cause the trademark registration process to slow down. The reduction of office staff, adjustments to working methods, and decrease in office efficiency have affected the speed of trademark registration.

2. Changes in regulations: Adjustments or updates to trademark regulations may lead to changes in the review process, making trademark registration more complex or time-consuming.

3. Increase in the number of applications: The increase in the number of trademark applications may increase the workload of the Trademark Office, thus prolonging the review cycle.

4. Technology upgrade: The Trademark Office may carry out system upgrades or technology improvements. These changes may slow down the process in the short term, but are expected to improve long-term efficiency.

5. Resource limitations: The Trademark Office may face human, financial and other resource constraints, which may also affect the speed of review.

Please note that these are just some possible reasons and may vary by country or region. If you are concerned about the slowdown in trademark registration in a specific country or region, it is recommended to check the official announcement of the trademark office there or contact the relevant department for detailed information.
