IPC Classification Table The classification table defines five classification principles:

1, overall classification

Some technical topics should be classified as a whole as far as possible, rather than classifying its components separately.

2. Classification by function

Technical topics are classified into functional classification positions according to functional classification; If the function classification position does not exist in the classification table, it should be classified into the appropriate application classification position.

3. Application classification

Some technical topics are classified into application classification positions according to application classification; If the application classification location does not exist in the classification table, it should be classified into the appropriate functional classification location.

4. Give consideration to functional classification and application classification.

Some technical topics are divided into functional classification bits and application classification bits according to functional classification. If the function classification position does not exist in the classification table, it is only classified as the application classification position; If no classification bits are applied in the classification table, it is only divided into functional classification bits.

5. Classification of independent claims and dependent claims.
