This particular technical field is often related to the lowest possible position of an invention or utility model in the international patent classification table.
For invention or utility model patents, it is necessary to set reasonable creative judgment standards respectively. Because the division of technical fields is closely related to the level of patent creativity requirements, it is very important to consider the existing technical fields when comparing technologies.
In the trial practice, the determined technical field should be the specific technical field to which the technical scheme of the claimed invention or utility model belongs or applies, not the superior or adjacent technical field.
Precautions:
1. Usually, the technical field to which it belongs can be determined according to the international patent classification table, and the lowest classification position can be determined as far as possible;
2. It shall reflect the subject name and invention type of the technical scheme for which the invention or utility model requires protection;
3. The distinguishing technical features of the invention or utility model that are improved relative to the nearest existing technology shall not be stated.
