A provisional patent application is not a patent, and moreover, by no means becomes a patent, with the single uncommon exception noted below. It automatically expires following twelve months following the day of filing and can not be revived.
It does present a priority date for concurrent later-filed non-provisional applications for the content that is in the provisional. This indicates that references that could defeat the later-filed application as to the matter in the provisional (but which could not defeat the provisional filing date) will now not be utilized to defeat the later-filed application. Further, it does not subtract from the twenty year term of the later-filed application unless it is genuinely converted as discussed below.
Though patent attorneys usually speak of "converting" a provisional into a non-provisional, this is not often an accurate description of the case (with a single exception), considering that the provisional has no life beyond its twelve-month term and "converting" is frequently accomplished by filing a non-provisional application that claims benefit of the filing date of the provisional. Thus, the provisional is primarily a signifies for delaying the filing of a non-provisional patent application, while nonetheless obtaining benefit of the earlier filing date of the provisional. (The single exception as to "converting" is that a provisional patent application can be truly converted with an extra processing fee if it has a least 1 claim, or is amended to contain at least one claim, but this procedure is rarely carried out, given that now the term of the resulting non-provisional will be twenty years from the date of the provisional filing, thereby losing a year.)
A provisional patent application needs a full written specification and all the drawing figures, but does not need claims. It is by no means examined (unless genuinely converted) other than to make sure that the proper papers are present.
Lastly, a provisional patent application in no way sees the light of day and remains confidential, unless a non-provisional patent application (or a Patent Cooperation Treaty application -- to preserve foreign filing rights -- or a design application) takes priority to it.

Non-provisional
A non-provisional patent application, occasionally called a "regular" patent application or just a "patent application", is a "actual" application for a patent. It will be examined, and ultimately, via the examination process can mature into a patent. It is "term" or life ends twenty years from the earliest priority date, which may well be the date it is filed or the date that an application from which it takes priority benefit is filed. (See above for the impact of a provisional priority date.)
A total non-provisional patent application consists of at least a specification, all the drawing figures and at least 1 claim. Claims are the invention. The specification and drawings need to disclose what is in the claims, but they do not comprise the invention, only the claims do. Twenty claims are paid for with the filing fee, of which three may well be independent claims. (Independent claims stand alone. The remaining are dependent claims which refer to an additional claim and thus can not stand alone.)
There are several varieties of non-provisional patent applications, which includes the "parent" application and such "youngsters" as divisional patent applications (occasionally the United States Patent & Trademark Office (USPTO) examiner demands restriction in between a lot more than 1 invention in the patent application just after proceeding with one selected invention, the other or other people can be filed as divisionals), continuation patent applications (typically only a new set of claims to the original invention) and continuation-in-portion patent applications (the original patent application plus some new matter added -- this is the only way to add new matter to a patent application).

Which Expenses Much less
Many men and women feel that a provisional patent application is much less costly way to get a patent than a non-provisional patent application. On the other hand, this is not the case.
Once again, given that the provisional expires and a non-provisional ought to be filed to take priority to the provisional, this two-step method is a great deal more pricey. It is true that a provisional patent application is the least expensive way to get "Patent Pending" status, but that will expire soon after a year unless the non-provisional is filed inside that time.
Further, in order to be completely enabling and not just a waste of time and money, the provisional should include almost everything that a non-provisional would contain except the claims. That constitutes about ninety percent of the cost of a patent. Later, the non-provisional that is filed taking priority to the provisional will cost about twenty to thirty percent far more. Thus, the provisional route is the much more high priced route to acquiring a patent.
Notwithstanding, as noted beneath, there are often beneficial reasons to file a provisional patent application and incur the further costs.
How to Pick
When to use a provisional
There are at least two superb factors to file a provisional patent application:
1. When an invention is totally definable, but will likely demand further improvements that can be accomplished inside a year, that is a good time to file a provisional patent application on the existing invention. The key is that the improvements should be completed inside a year so that the non-provisional can be filed with the improvements throughout the pendency of the provisional so that priority as to the matter of the original invention defined in the provisional can be taken prior to the provisional expires.
2. On occasion, an individual has an invention that they merely want to sell or license and are particular that they will have identified somebody to invest in or license within the one-year pendency of the provisional patent application. Alternately, if they do not obtain somebody, they plan to let the provisional patent application expire with out filing a non-provisional patent application and incur no further expenditures.
When to use a non-provisional
Pretty considerably any other reason than those two above will be a very good reason for filing a non-provisional. Namely, if you want to get a patent and reason 1 above does not apply, you should really quickly file a non-provisional patent application and get the procedure going.
