In the patent application, the column of case status is "one callback to the real trial of the case". What does this mean?

Replies to the first review comments have been received, and further review is under way.

The time limit for a patent application, a telephone representative's notice of the first examination opinion, was returned to the case representative and reached the examiner. The actual examination of a telephone call refers to that the patent has entered the actual examination and has issued the first notice of examination opinions, and the patent applicant or patent agency refutes Patent examiners's uncreative opinions according to the examination results and submits them to the Patent Office.

It indicates that the patent or invention applied by the applicant has entered the substantive examination stage.

Extended data:

Substantive examination stage: after the publication of the application for a patent for invention, if the applicant puts forward a request for substantive examination and it has taken effect, the applicant will enter the substantive examination procedure. If the applicant fails to make a request for real trial within three years from the date of application, or the request for real trial does not take effect, the application shall be deemed to have been withdrawn.

In the actual trial process, whether the patent application is novel, creative and practical will be comprehensively examined. After examination, if it is found that the application does not meet the authorization conditions or there are various defects, the applicant will be notified to state his opinions or make amendments within the specified time. If no reply is made within the time limit, the application shall be deemed to have been withdrawn. If the application still fails to meet the requirements after repeated replies, the application shall be rejected. The actual probation period is very long. If it is not authorized within two years from the date of application, the application maintenance fee shall be paid every year from the third year. Failing to pay within the time limit shall be deemed to have withdrawn the application. If the substantive examination finds no reason for rejection, it shall enter the authorization procedure as required.

By 20 13, the authorization rate of invention patents announced by People's Republic of China (PRC) and China National Intellectual Property Administration is 40%-50%, that is to say, the overall authorization rate of invention patents is less than half. Therefore, the risk of applying for a patent for invention is relatively high, so we must make full preparations.
