Patent US gives inventor exclusive rights on the invention. The exclusive rights will prevent others to make, use, import, sell or offer to sell the invention without the inventor’s permission. In exchange for Patent US grant, the inventors must disclose their invention to the public in the form of patent application. Patent US does not grant inventors the right to make, use, sell, or import their inventions.
Patent US has several requirements for an invention to be patentable:
• New - the invention must not have been disclosed in any way - by word of mouth, journal article or abstract. An invention may be completely new or an improvement on an existing invention.
• Involve an inventive step - The invention should not be obvious to another scientist with experience of the field, though in practice this is often difficult to judge, particularly if the invention involves an incremental improvement.
• Must have industrial application - The invention should be capable of use within some kind of industry, where industry has the broad definition of anything distinct from purely intellectual or aesthetic activity. In practical terms this means that the invention takes the form of a device or apparatus, a product such as a new material or substance or a new industrial process or method of application.
There are three types of Patent US granted by the Patent US office, these are: utility patents, design patents and plant patents. There are specific requirements for the Patent US applications. Patent US application must include a specification, including a description and claim(s); an oath or declaration identifying the applicant(s) believing to be the original inventor(s); a drawing when necessary; and the filing fee. Prior to 1870, a model of the invention was required as well. Today, a model is almost never required.
Patent search is an important phase all applications for Patent US undergo. Inventors can make a search of patents already granted, text books, journals and other publications to be sure that someone else has not already invented their idea. The U.S.P.T.O. Patent US database is the most popular means of search available to a layperson. The Patent US database only contains "keyword" searchable patent data from 1975 forward. Patent US database, publications and journals are also an important step to assure the patentability of the invention. Inventors can make a search of patents already granted in text books, journals and other publications to be sure that someone else has not already invented their idea. They may hire someone to do it for them or may do the search on the US patent information at the Public Search Room of the Patent US and Trademark Office in Arlington, Virginia, on the PTO web page on the Internet, or at one of the Patent US and Trademark Depository Libraries across the country.
