The Do-It-Yourself Patent Search
If you decide to do the patent search yourself, you have several search methods available: The USPTO (United States Patent Trade Office) Public Search Facility. The USPTO operates a Patent Public Search Facility located in Alexandria, Virginia. Here every U.S. patent granted since 1790 may be searched and examined. Many inventors like to make at least one pilgrimage to the Patent Public Search Facility. It's located fewer than 15 minutes from National Airport by taxi; Metro Rail serves it off the Blue and Yellow lines, King Street Station; and several hotels are within walking distance, so it's easy to get to and around.How to Patent Your Idea
Contrary to popular belief, you can't get a patent for something that's still in idea form; you must be able to apply your idea in a concrete way. This doesn't mean that you have to build a prototype of your invention before you can get a patent. However, you have to be able to draw or describe it in enough detail so that someone else could make it and use it. Have a question? Get an answer from a lawyer now!Non-Provisional Application
Although you can convert a provisional application into a non-provisional application, the USPTO recommends filing a separate non-provisional application that references the earlier provisional one. Doing so can extend the time your invention is protected by up to one year. A non-provisional application includes a lengthy written document with a description of your invention and all the things you claim you invented, as well as drawings, an oath or declaration and fees for the filing, research and examination of the application. The USPTO recommends using a registered patent attorney to draft and file your non-provisional application. USPTO regulations include specific requirements for the format of applications and the necessary drawings -- and examiners reject applications that don't meet these requirements.Who can apply for a patent?
A patent must be applied for only in the name(s) of the actual inventor(s). However, the inventor can sell or assign the patent to someone else. Prior art includes any patents related to your invention, any published articles about your invention, and any public demonstrations. This determines if your idea has been patented before or publicly disclosed making it unpatentable.You Can't Be Too Obvious
Even if you don't find the prior art to prove it - you will not get a patent if your invention is not different enough from similiar inventions that are already out there. A patent maybe refused if the differences between your invention and another invention are too obvious. Your invention must be sufficiently different from what has been used or described before that it may be said to be nonobvious to a person having ordinary skill in the area of technology related to your invention . For example, the substitution of one material for another, or changes in size, are ordinarily not patentable. You can't paint it red and make it twice as big and expect a patent. Another example of "nonobvious to a person having ordinary skill in the area of technology related to your invention" could be the following. An electronics engineer looks at a circuit board and observes that it is just like another circuit board except that a few parts are substituted. Someone who is not familiar with circuit boards may not understand that the two boards are very similar, however, someone with training thinks that it is obvious. You would want the electronics engineer to look at the circuit board that you want to patent and say, "heah, why didn't I think of that!"
