A basic Patent Search is researching various data sources to determine if there is prior art that discloses your invention. Prior art is existing patents, patent applications, and publications (non-patent literature). It is found around the world. Prior art is those existing documents that are similar to your invention, or describe your invention.

What you need?

You will need three things for input into the search engines to do a patent search. You will need the following:

  • Description
  • Keywords
  • Classification

Description:

The place to start a patent search is with the description of the invention. A description of the invention that is just a simple sentence or two is the easiest to work with. A concise description is easier to work with. This is because what you will need for actual searching in databases is just the right few keywords and the right classification(s) for the invention. You are looking to locate all the existing products and processes that are the most similar to our invention.

Keywords:

The description is used to develop a good set of keywords to use for searching. The best keywords to use are those terms and phrases about the invention and its field of use that describe it most accurately and completely. A good concise description will be simpler to use. The concise description likely already has many if not all of the keywords that you will need to start a search.

Classification:

The final piece to the input for a patent search is the classification. The classification system to use is the CPC Scheme (find it on the USPTO website). The CPC is the Cooperative Patent Classification system. The CPC (like all classification systems) categorizes inventions into classes. The idea is that all the other inventions that are like your invention will be in the same class(es). Searching by class is essential to a complete patent search.

TIP: If you don’t know or can’t find the class(es) for your invention, one place to start is the class(es) of the patents that you find with keyword searching. After you find a patent similar to your invention, you can use that patents classification as a starting point for your invention.

Places to Search | Where to Search | What Data Sources to Search

You should search the following data sources, at a minimum. The more places searched the more complete the search. However, the following list of sources will give you a good start. And, quite likely, more prior art (existing stuff like yours) than you were expecting.

  • United States Patent and Trademark Office (USPTO) – uspto.gov
  • European Patent Office (EPO) – epo.org
  • World Intellectual Property Organization (WIPO) – wipo.int
  • Google Patents – patents.google.com
