Hello, engineer, I'm a college student. Applied for a patent for utility model and made two revisions. What if I can't contact the examiner now?

How long has the correction been submitted? If you can't get through, please try again. You can also check it on the official website of China National Intellectual Property Administration. Generally, there is not much problem in making corrections under the utility model. Basically, just correct the mistakes mentioned in the correction. There should be no problem. If you can apply for a permit, wait patiently.
