How do patent examiners determine the appropriate classification for a patent application?

Patent examiners determine the appropriate classification for a patent application through a systematic process:

  • Analyze the invention’s technical content and novel features
  • Identify the most relevant CPC symbols that cover the invention
  • Consider both primary and secondary classifications
  • Consult classification definitions and guidelines

While MPEP 902 does not provide specific details on this process, it emphasizes the importance of proper classification: “Proper classification is essential for an effective and efficient search of the prior art.” Examiners use their technical expertise and training in classification systems to ensure accurate categorization of patent applications.
