1, the name of the invention or utility model
The name should be concise and to the point, using technical terms commonly used in this technical field, so as to clearly reflect and embody the theme and type of invention. Don't use non-technical terms, names, trademarks, models or product names of inventions, or commercial propaganda terms. The name should preferably correspond to the categories and groups in the international classification table, generally no more than 25 Chinese characters.
2. Belonging to the technical field
The technical field refers to the technical field to which the invention directly belongs or directly applies, which is neither the broad technical field to which it belongs or applies, nor its adjacent technical field, nor the invention or utility model itself.
3. Background technology
Also known as existing technology, this part should focus on describing and evaluating the existing technology before the application date, that is, recording the background technology known by the applicant, which has a reference function for understanding, searching and reviewing the application. Generally, at least one prior art document closest to this application should be cited, and if necessary, several relatively close comparative documents can be cited, which can be patent documents or non-patent documents.
A brief introduction to the existing technology should include three aspects:
(1) indicate its source, generally by giving comparison documents or pointing out public information;
(2) Briefly explain the main related contents of the existing technology, such as the main structure and principle, or the technical means and methods adopted;
(3) Objectively point out the problems and deficiencies of the existing technology, explain the reasons for these problems and deficiencies when possible, and avoid using defamatory language.
