A provisional application is also field in the patent office as it is a sub version of formal patent application and will serve to provide a date of invention, and a priority date. The provisional application can never issue into a US patent because it will not be evaluated by the patent office. But it will be abandoned by the Patent Office if it will not replaced by actual patent within 12 months. Thus it will become worthless to the inventor. To summaries we can say that if inventor is not able to file an actual patent application within one year, the provisional one will expire.
That is why the inventor who is filing a provisional patent application should keep in mind that he will have to file an original application in less than a year after the public presentation of the invention. The format of filling a provisional application is same like original apart from that the claims can be not there. All this has been mentioned in the section 112 of the patent laws. Keep in mind that all the descriptions of your invention should be in written form. It should include the process of making and method of its utilisation. The description should be clear, concise and exact as was explained very well in the article on https://www.davidicke.com/article/501936/choosing-inventhelp-help-invention.
According to law there are two requirements of filling a provisional patent application; enabling and the best mode. People, who have already filed an application, know the signification of these two terms. And those who are new in this aspect should evaluate these terms carefully in order to understand their needs in application.
Enabling or Facilitate – While evaluating the invention, the inventor should bring adequate details so that the reader who is related to the field can easily actually construct and utilize the invention.
Best mode – The inventor should not hide any merit as well as demerit related to the creation and make use of the invention. For illustration if he is aware that certain data related to the construction in a better way than the specified one that it is thought that the inventor is not setting the “best mode” of the invention.
You should have a required understanding of the subject of the invention. Only then you can file an application accurately. In other words, if the people are not able to understand your creation from your description then you must also provide them with drawings. Pictorial description can make it easy to understand. This can provide to give clear idea of the invention that what it is compiles of and how it functions. It is essential to present a rough sketch apart from the reason if it is unsuitable for the invention. A complete application often includes specification, cover sheet, related drawings and provisional application filing fee. A unit declaration should also be incorporated in order to allow the creator to give the reduced filing fee. The Patent Office offers a cover sheet that is used to make simpler the filing procedure.
