What role do classification definitions play in a classified patent search?
Classification definitions play a crucial role in guiding examiners during a classified patent search. MPEP 904.02(a) emphasizes their importance:
“The examiner should, on the basis of the disclosed features of the invention, descriptive material, and the field of search suggested by the classification definition, identify the subclasses, and perhaps classes, most likely to contain the prior art which could anticipate or render obvious the claimed invention.”
Classification definitions serve several key purposes:
- Provide a detailed description of the subject matter covered by a class or subclass
- Help examiners understand the scope and boundaries of each classification
- Suggest related areas that may contain relevant prior art
- Guide the examiner in determining which subclasses to search
By carefully reviewing classification definitions, examiners can ensure they are searching in the most relevant areas and conducting a thorough and efficient prior art search.
