how to check if an idea has been patented
There is no EASY way. If your invention is a new can opener, an existing patent for the same idea may never use the words can opener. For example, it may be described in broader terms: container de-sealer or metal wall scissor. The patent offices classification system helps a bit, but not much. Inventors tend not to want to find their invention, so, they type in --can opener-- and look at a few and say they couldn't find it. You have to look for it like you want to find it. try different search terms. when you find one thats close, look at the references cited in that application and look for other patents wherein the close one was cited.Meaning of Novel, Nonobvious, and Useful
New and Novel: For a United States patent the invention must never have been made public in any way, anywhere in the world, a year before the date on which an application for a patent is filed. Original and Nonobvious: An invention involves an inventive step if, when compared with what is already known, it would not be obvious to someone with a good knowledge and experience of the subject, for example, if you just make cosmetic changes that is obvious. Useful: This means that the invention must take the practical form of an apparatus or device, it has to do something.Utility patents

Patents are valuable - Patents may have commercial value but that usually depends upon how it has been used. A patent means the invention works as verified by the government - The U.S. government does not test inventions to see if they work. A patent gives the owner the exclusive right to make, use, and sell the invention - A patent gives its owner the right to EXCLUDE others from making, using, and selling exactly what is covered by their patent claims. A holder of a prior patent with broader claims may prevent the inventor whose patent has narrower claims from using the inventor's own patent. A patent right is exclusory only.Guide To Patenting And USPTO Patent Applications - What can be patented? What does novelty mean?
In legal terms, any person who invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof , may obtain a patent, subject to the conditions and requirements of the law. A process is defined by law as a process, act or method, and primarily includes industrial or technical processes. A process is the way an invention performs rather than the way it is structured. Computer software performs a certain way, it makes certain processes. Another example would be the process for making a drug. Machine should need no explanation. The term manufacture refers to articles which are made, and includes all manufactured articles.
