How does subclass harmonization affect patent searches?
Subclass harmonization significantly impacts patent searches by creating a more unified classification system across major patent offices. The MPEP’s description of harmonized subclasses between the USPC, EPO, and JPO indicates that:
“Subclasses that have been harmonized have a designation of “EPO,” “JPO,” or “EPO/JPO” in parentheses following the subclass title to indicate if the subclass has been harmonized with the EPO or JPO or with both systems.”
This harmonization allows searchers to:
- Use consistent classification codes across different patent databases
- Conduct more comprehensive prior art searches
- Reduce the likelihood of missing relevant patents due to classification differences
- Save time by avoiding the need to translate between different classification systems
Overall, harmonized subclasses enhance the efficiency and effectiveness of patent searches, particularly for those conducting global patent landscape analyses or international patentability assessments.
