- State of the Art Search: To understand current trends and developments in a particular field.
- Competitive Intelligence: To monitor competitors’ patent activities and strategies.
-
Choose Appropriate Keywords and Search Terms:
- Keywords: Use specific terms related to the invention or technology. Include synonyms and variations.
- Patent Classifications: Use classification codes like the International Patent Classification (IPC) or Cooperative Patent Classification (CPC) to narrow down search results to specific technical fields.
- Inventors and Assignees: Search by the names of inventors or companies associated with the patents.
- Publication and Application Numbers: If you know specific patent numbers, use them for precise searches.

Utilize Search Tools and Techniques:

- Full-Text Search: Search within the full text of patent documents for detailed information.
- Image Search: Use available tools to search for patents with specific images or diagrams.
-
Filter and Refine Search Results:
- Apply filters for publication date, jurisdiction, patent status (granted, pending, or expired), and other criteria to narrow down the results.
- Use patent citations to find related patents that reference or are referenced by the patents in your search results.
-
Analyze and Review Patent Documents:
- Abstract and Claims: Review these sections first to understand the scope and novelty of the invention.
- Drawings and Descriptions: Examine these for detailed information about the invention's structure and operation.
- Legal Status: Check the current legal status to see if the patent is still active or if any litigation is ongoing.
-
Use Alerts and Monitoring Tools:
- Set up alerts to stay updated on new patents or applications in your field of interest.
- Use monitoring tools to track changes in the legal status or citation of specific patents.
