How to use Google Patents for Patent Searching

  1. Go to Google Patents (https://patents.google.com/).
  2. Enter relevant keywords related to your invention in the search bar. You can use multiple keywords to narrow down your search results.
  3. Use the filters on the left-hand side of the page to refine your search results. You can filter by patent type, filing date, inventor, assignee, and more.
  4. Click on a patent from the search results to view the full patent document. You can also view related patents, citations, and legal events associated with the patent.
  5. Analyze the patent document to determine if it is relevant to your invention. You can also use the “similar documents” section on the right-hand side of the page to find other patents that are similar to the one you are viewing.

Patent searching is a vital step for inventors looking to ensure that their inventions are original and do not infringe on existing patents. Effective patent searching requires a well-planned approach that involves refining search queries, narrowing search results, and evaluating search results.

3 Tips for Refining Google Patent Search Queries

  1. Use specific keywords: Use specific keywords related to your invention, such as the name of the technology or product, materials used, or the intended use of the invention. Avoid using generic or broad keywords that will yield a large number of search results.
  2. Use Boolean operators: Use Boolean operators (AND, OR, NOT) to refine your search queries. For example, if you are searching for a patent related to “solar panels,” you can use the operator AND to narrow down the search to patents related to “solar panels AND efficiency.”
  3. Use quotation marks: Use quotation marks to search for exact phrases. For example, if you are searching for a patent related to “renewable energy,” use quotation marks to find exact matches for that phrase.

3 Tips for Narrowing Google Patent Search Results

  1. Use filters: Most patent search tools, including Google Patents, offer filters that you can use to narrow down your search results. Use filters such as inventor, assignee, patent type, filing date, and more to refine your search results.
  2. Use citation searches: Use citation searches to find patents that have cited a particular patent. This is useful when looking for patents that are related to a specific technology or invention.
  3. Use classification searches: Use classification searches to find patents based on their classification. Patent classifications are organized by the USPTO and other patent offices and can help you identify patents related to your invention.

3 Tips for Evaluating Google Patent Search Results

  1. Read the abstract and claims: The abstract and claims sections of a patent document provide a summary of the invention and its scope. Read these sections to determine if the patent is relevant to your invention.
  2. Look at the drawings and specifications: The drawings and specifications sections of a patent document provide detailed information about the invention. Look at these sections to determine if the patent is similar to your invention.
  3. Check legal events: Check legal events associated with a patent to determine if it has been litigated or challenged. This can help you determine the strength of the patent and whether it is relevant to your invention.
