There are a variety of tutorials that will help in your ultimate goal of obtaining a patent.
When you think you have a patented idea, before you begin the patent process, you should answer these few questions:
1. Understand what a patent does
2. Keep a record of your invention
3. Make sure your invention qualifies
4. Assess the commercial potential
5. Do a thorough patent search
Once you think you have a unique idea, you can begin the process of seaching products that have been patented to make sure your idea has not already been designed, developed or submitted and not yet approved.
The first place to start would be browsing the USPTO Web Site.
The Seven Steps in a Preliminary Search of U.S. Patents and Published Patent Applications
1. Brainstorm terms to describe the invention.
2. Use these terms to find initial relevant Cooperative Patent Classification using the USPTO website's Site Search box (www.uspto.gov). In the Site search box found in the top right hand corner of the home page enter "CPC Scheme [plus keywords(s) describing invention]".
3. Verify the relevancy of CPC classification you found by reviewing the CPC Classification Definition linked to it (if there is one).
4. Retrieve U.S. patent documents with the CPC classification you selected in the PatFT (Patents Full-Text and Image) database. Review and narrow down the most relevant patents publications by initially focusing on the front page information of abstract and representative drawings.
5. Using this selected set of most relevant patent publications, review each one in-depth for similarity to your own invention, paying close attention to the additional drawings pages, the specification and especially the claims. References cited by the applicant and/or patent examiner may lead you to additional relevant patents.
6. Retrieve U.S. published patent applications with the CPC classification you selected in Step 3 in the AppFT (Applications Full-Text and Image) database. Use the same search approach used in Step 4 of first narrowing down your results to the most relevant patent applications by studying the abstract and representative drawings of each on its front page. Then examine the selected published patent applications closely, paying close attendion to the additional drawings pages, the specifications and especially the claims.
7. Broaden your search to find additional U.S. patent publications using keyword searching in PatFT or AppFT databases, classification searching of non-U.S. 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.
Seven Step Strategy Tutorial and Handout
The Patent and Trademark Resource Center Program also provides a CBT (computer based training) tutorial with a detailed review of the Seven Step Strategy. The CBT has been changed to reflect the current CPC searching method.
