An international patent search is an IP convention that helps an inventor seek patent protection in many countries at the same time by looking for similar patents worldwide. In addition, Patent International conducts an extensive patent search on your behalf to avoid any opposition or conflicts resulting from similar patents filed or granted elsewhere.

We understand the benefits of patents and the degree of innovation they bring to the market. We know the value of these business assets to our customers, which is why Patent International is always working to enhance our services so that we can provide you with the best patent strategy for moving forward with your discoveries.

International patent research is conducted in seven main steps:

Seven Step Strategy

  1. Brainstorm several different terms related to your innovation.
  2. Using the USPTO’s Classification Text Search Tool, search for the first appropriate Cooperative. Search for Patent Classifications using these terms.
    • In the Search Toolbox, type the keyword or keywords you want to look up.
    • If you were looking for CPC Classifications for patents linked to umbrellas, for example, you would type “umbrella” into the search box.
    • Because Cooperative Patent Classification is the default search system, the button “All CPC” is chosen.
    • Select “Search” from the drop-down menu.
    • Examine the Class Schemes in the resulting classification to find the most appropriate categorization for your idea.
    • If your Classification Text search yields no results, consider substituting synonyms for the words you’re using to describe your innovation, such as the alternative terms you came up with in Step 01.
  3. Review the CPC Classification Definition linked to it to confirm the relevance of the CPC classification you found if there is one.
  4. In the Patents Full-Text and Image database, find U.S. patent documents with the CPC classification you chose. Then, examine and narrow down the most relevant patent papers by focusing on the abstract and representative illustrations on the main page.
  5. Examine each patent publication in detail for similarities to your invention, giving careful attention to the supplemental drawing’s pages, the specification, and, most importantly, the claims. Additional relevant patents may be found through references mentioned by the applicant or patent examiner.
  6. In the Applications Full-Text and Image database, look for the U.S. published patent applications with the CPC classification you chose in Step 3. Next, use the same search strategy as in Step 4 to filter down your results to the most relevant patent applications by looking at the abstract and representative illustrations on the front page of each one. Then carefully review the selected published patent applications, giving special attention to the extra drawing pages, specifications, and, most importantly, the claims.
  7. Use keyword searching in the PatFT or AppFT databases, classification searching of non-US patents on the European Patent Office’s Worldwide Espacenet patent database, and searching non-patent literature disclosures of inventions using the free electronic and print resources of your nearest Patent and Trademark Resource Center to expand your search for additional U.S. patent publications.
