What does a Patent Search cost?

How much does a Patentability Search cost? At Grell & Watson Patent Attorneys we perform an in person US search of patents at the US Patent Office verses performing an online search.  The US Patent Office enables searches for patents differently than online patent searches which focus on keywords searching. The US Patent Office groups patents by a classification system and sub-classification system.  Therefore to find the patents that relate to your invention you drill down based on class and sub-class until you find similar patents.  The US Patent Office makes hard copies available to review to see if the figures and text are relevant to the invention being searched.   If you find a US patent or US Patent Application that is relevant cross reference its class and sub-class assignment against the class or classes being searched.

What is a Patentability Search? Patent searching is the act to search patents and published patent applications that are relevant or related to your invention, which may be considered important “prior art” references when applying for a patent. Prior art is  any product, publication, or patent, that may be relevant or related to your invention. In order to be patentable your invention must have a new part or element not found in prior art to be new or novel. A patent searcher reviews the drawings and text of US patents and patent applications to determine whether your invention is new and determines the scope of potential patentability.

How to do a Search yourself?

  • How to conduct a Patententability Search?  In order for an invention or idea to be patentable your invention must be new meaning you have a new part, element, feature, or step in a process as compared to other patents and patent applications.

  • Let G&W be your Patent Searcher – We offer a comprehensive US Patent Office search performed at the US Patent Office records room, a physical search in person search at the US Patent Office. So it makes sense to perform your own initial online searching in the beginning, but be careful relying on your own search before you spend thousands of dollars  to obtain a patent.  You will want to review the patent searching websites United States Patent Office or Google Search or FreePatentsOnline. It is advisable for every inventor to at least do a preliminary search of US patents on their own.  If you can find something during your search of US patents that is close to your invention analyze and compare elements of each.
    •   Note database search engines have search query flaws and have missing patents within their databases.  Occasionally, I have looked for patents in these databases I know to exist and cannot always find them. Additionally, the most recent patents are not always immediately available.
    • The US Patent Office also has a helpful US search tutorial and frequently asked questions to educate inventors on how to use the online search features.
    • Try various search terms to make sure you are covering all possible descriptions of the invention.
    • Once you receive a short list of relevant patents you need to read the patents, high light the elements or parts and see which ones are relevant.
    •  Also bear in mind that this search did not include foreign patents and other publications, U.S. and foreign, that may be available to an examiner during the examination of a patent application.
    • Additionally, unpublished pending patent applications cannot be searched.  As a result, favorable patent searches should not be taken as a guarantee that the invention is patentable. It is possible that a relevant reference may have not been uncovered even by an experienced patent searcher.
    •  You are also reminded that any public use, offer for sale or sale in the United States prior to the filing of a US patent application may prohibit the granting of a U. S. patent.  Foreign patent laws in this regard may be much more restrictive than U.S. law.  Protect your invention by first filing a Provisional Patent Application.
