Introduction to U.S. Patent Searches

A U.S. patent search (a.k.a. USPTO patent search, patent office search) involves a patent searcher searching the public records at the U.S. Patent & Trademark Office (USPTO) for patent records that could materially affect the patentability of your invention.  This page provides an overview of the U.S. patent search process and the patent search services performed by Neustel Law Offices.


What is “Searched” in a U.S. Patent Search?

A U.S. patent search only researches the following types of U.S. patent documents:

  • Granted U.S. patents.  All patents (not patent applications) granted by the USPTO are published and are searchable by anyone.

  • Published U.S. patent applications.  Some patent applications are “published” by the USPTO after 18 months of pendency and are also searchable.  Keep in mind that not all patent applications are published even if they have been patent pending for more than 18 months.

If you want additional items searched, talk to your patent attorney to see if they can assist you.


What is Not Searched in a U.S. Patent Search

A U.S. patent search does not search for the following types of items:

  • Foreign Patents or Foreign Patent Applications
     
  • Non-Published U.S. Patent Applications
     
  • Commercial Products Previously and Currently Sold
     
  • Non-Patent Publications (e.g. Technical Publications)


A Patent Search is Not a Guarantee of Patentability

While a U.S. patent search is generally accurate, there are no guarantees that every patent will be found by the patent searcher (there are millions of United States patents to search through).  In addition, while your patent attorney’s patentability opinion may indicate that he/she believes that your invention is patentable based upon the patents found in the patent search, a USPTO Examiner may have a different opinion of patentability based upon the same patents (or the USPTO Patent Examiner may cite additional patents that they find during their own patent search).  Hence, while U.S. patent searches are generally reliable, they are not a guarantee that you will get a patent or that a USPTO Patent Examiner will not find additional patents.
