First, review the list of what can and cannot be patented and determine if your invention falls into one of those categories.
Second, learn the basics of the patenting process from the materials provided by the USPTO at 800-PTO-9199 or 703-308-HELP or under "General Information." .
Next, a search of all previous public disclosures (prior art) including, but not limited to previously patented inventions in the U.S. (prior art) should be conducted to determine if your invention has been publicly disclosed and thus is not patentable. A search of foreign patents and printed publications should also be conducted. While a search of the prior art before the filing of an application is not required, it is advisable to do so. A registered attorney or agent is often a useful resource for performance of a patentability search. After an application is filed, the USPTO will conduct a search as part of the official examination process. Conducting a thorough patent search is difficult, particularly for the novice. Patent searching is a learned skill. The best advice for the novice is to contact the nearest Patent and Trademark Resource Center (PTRC) and seek out search experts to help in setting up a search strategy. If you are in the Washington, D.C., area, the USPTO provides public access to collections of patents, trademarks, and other documents at its Search Facilities located in Alexandria, Virginia. These facilities are open weekdays (except holidays) from 8:00 a.m. to 8:00 p.m.

It is possible, however difficult, for you to conduct your own search. For an introduction to patent searching for the novice please refer to the Patent and Trademark Depository at the Richard W. McKinney Engineering Library, the University of Texas at Austin . Although some of the instructions given here may be unique to the Austin library and the focus of this introduction is on the Cassis CD-ROM products, the fundamentals of patent searching remain the same for any location.
You should not assume that your invention has not been patented even if you find no evidence of it being publicly disclosed. It's important to remember that a thorough examination at the USPTO may uncover U.S. and foreign patents as well as non-patent literature.
