A patent search is part of your search for prior art (no, not paintings.) Prior art is any body of knowledge that relates to your invention. Prior art would include previous patents, trade journal articles, publications (including data books and catalogs), public discussions, trade shows, or public use or sales anywhere in the world. As discussed previously, the search for prior art helps prove the novel and nonobvious legal conditions that are required for a patent to be granted.
The Joys of Conducting a Patent SearchA patent search involves searching different databases to see if your idea has already been patented, to know if you can patent your idea. The results of a good patent search should reveal any identical, similar, or partially similar inventions to the one you might patent.As a bonus, viewing and reading already issued patents will:
