You cannot patent an invention that was previously invented, whether it was patented or not, if it can be found in any publication, such as a magazine article, catalog, etc.. I offer searches to locate U.S. patents and published patent applications that could prevent patenting of your invention (novelty search), and/or prevent you from producing a product (infringement search). I provide copies of the most relevant patents found, and my written opinion of your patentability in view of the prior technology. No search covers pending U.S. patent applications for the first 18 months, since they are confidential to the U.S. Patent Office. The searches do not cover foreign patents or non-patent publications in depth. There is a big difference in the quality of search firms. I use the best one I have tried. You may phone me for details.

Free Patent Search (Do it yourself)
Below is the US Patent Office website address. You can perform free searches back to 1976 there. Check the help information on that website to understand the procedures and limitations. Skill, training, and experience are helpful in patent searching, so you may not be able to do it as well as I can. Also, it is a considerable amount of work. However, I encourage you to try it. Start with key word searches. Determine the classes/subclasses for completing the search, and follow relevant forward and backward patent references from each patent to others.
