What is prior art?
Prior art is all information that has been disclosed to the public in any form about an invention before a given date. Prior art includes things like any patents related to your invention, any published articles about your invention, and any public demonstrations. prior art is "the total body of knowledge, which teaches or otherwise relates directly to an invention. This is the primary criteria in determining the patentability of a new invention. Establishes novelty and unobviousness of the art that relates to the invention in question. Prior art references include documentary sources such as patents and publications from anywhere in the world, and nondocumentary sources such as things known or used publicly."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.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.How do I know if my idea is patentable?
First, check to see if your idea qualifies. Second, learn the basics of the patenting process. Next, do a search for of all previous public disclosures that concern your invention. These public disclosures are called prior art. A registered patent attorney or agent can be hired to do a patentability search for prior art, and a big part of that is searching for U.S. and foreign patents that compete with your invention. After an application is filed, the USPTO will conduct their own patentability search as part of the official examination process.What is reissue?
Patent law states "On taking up an application for examination or a patent in a reexamination proceeding, the examiner shall make a thorough study thereof and shall make a thorough investigation of the available prior art relating to the subject matter of the claimed invention." This means that prior art could disqualify your application for a patent.
