A provisional patent application will never itself mature into an issued patent, but in the right circumstance (and done properly) a provisional patent application can be a very useful tool for inventors. This is particularly true now that the United States is a first to file country, which absolutely must be interpreted as inventors needing to file first before disclosing anything about their invention, offering it for sale or using the invention publicly.
But let’s take a step back and start at the beginning.
Since June 8, 1995, the United States Patent and Trademark Office (USPTO) has offered inventors the option of filing a provisional application for patent. This was the date on which patent term changed from 17 years from issuance of the patent to 20 years from the earliest filing date of the non-provisional utility patent application. Changing patent term in this way would have lead to a peculiarity though. When you invent in the United States you must obtain a foreign filing license prior to filing overseas, which is most easily accomplished by filing a patent application in the U.S. But if you file a non-provisional utility patent application the patent term clock starts to run. Inventors outside the United States would be able to file a patent application in the country where they lived, which would lock in priority but not start the patent term clock running (because patent term starts based on the filing of a U.S. non-provisional patent application, not the filing of a foreign patent application).

To address this issue, which would have given foreign citizens more rights than U.S. citizens, Congress simultaneously created a provisional patent application, which can be filed by anyone, locks in your priority filing date, but which like a foreign application does not start the patent term clock. Thus, with a provisional patent application, you get the benefit of a priority filing date without the patent term starting.
A provisional patent application also provides a lower-cost first patent filing. For example, the filing fees as of this writing for a small entity are $140 for a provisional patent application, which compares to $730 for a non-provisional patent application. For more on fees see USPTO Fee Schedule.
A provisional application for patent is a U.S. national application for patent filed in the USPTO. It allows filing without a formal patent claim, oath or declaration. The focus is on describing the invention as completely as possible, and many formalistic requirements of a non-provisional patent application are unnecessary to satisfy. A provisional patent application also provides the means to establish an early effective filing date in a later filed non-provisional patent application. It also allows the term “Patent Pending” to be applied in connection with the description of the invention.
A provisional patent application has a pendency lasting 12 months from the date the provisional application is filed. The 12-month pendency period can be extended only in extraordinary circumstances. Therefore, an applicant MUST file a non-provisional patent application claiming the priority of a provisional patent application within 12 months. If you miss the 12 month deadline you may in extraordinary cases get an extra 2 months to claim priority to the provisional, but that currently comes with a hefty $1,700 fee and is only applicable if there is an inadvertent or mistaken failure to file within 12 months.
Although the filing fees of a provisional patent application are less than for a non-provisional patent application it is critically important that inventors understand that a provisional patent application MUST describe the invention as completely in a provisional patent application as is required in the non-provisional patent application. Thus, a carelessly prepared, informal provisional patent application will provide no benefit and likely will be harmful because it can be used as evidence that you did not have a complete invention. Therefore, while there are no formalities for a provisional patent application the invention must be described to the greatest extent possible.
So why would you use a provisional patent application if you need to describe the invention to the same level as a non-provisional patent application? The best use of a provisional patent application is to establish priority rights as soon as you have an invention that can be patented. In a first to file world you want to have a filing date as soon after your conception of the invention as possible. But in many, if not most circumstances, inventors will continue to work with the invention, improve what they’ve invented or work on additional versions of the invention. If you are going to continue working on the invention a provisional patent application is a great idea. File the provisional as reasonably soon as you can making sure to describe what you have presently with as much detail as possible. Then as you continue working on the invention as you make more advances you may want to file another provisional patent application. You can file multiple provisional patent applications and then within 12 months of the first provisional file a non-provisional patent application that claims priority back to each of the provisional patent applications filed within the last 12 months. By doing this you get priority for your invention as close in time to invention as possible, which can be extremely important. You can also wrap all the versions and aspects of your invention together into a single non-provisional patent application.
The aforementioned strategy is a good one because getting an early priority filing date is VERY important. Anything that comes after your priority filing date cannot be prior art. Prior art, which an examiner will use against you when they examine your application, comes from that set of information that is available before you file a patent application. So filing a provisional patent application early and often can be very useful. Of course, you must do it properly and properly with provisionals means you need to describe the invention completely.

There is No Such Thing as a Provisional Patent — First and foremost, there is no such thing as a provisional patent. It is absolutely critical to understand that a provisional application will never mature into an issued patent! Ultimately, if you are going to want to obtain a patent you will need to file a non-provisional utility patent application. Thus, a provisional patent application is best viewed as an economical first step on the path to a patent. CLICK HERE to Continue Reading.
The Benefits of a Provisional Patent Application — There is a great misunderstanding among many inventors and entrepreneurs regarding what many simply refer to as a “provisional patent.” The first thing that needs to be said is that there is no such thing as a “provisional patent.” Instead, what you file is called a provisional patent application. Like any other patent application, a provisional patent application is effective to stop the clock relative to so-called statutory bars and immediately upon filing a provisional patent application you can say you have a “patent pending.” CLICK HERE to Continue Reading
The Good, Bad & Ugly: Truth About Provisional Patent Applications — Poorly done provisional patent applications are almost certainly useless for their intended purpose, but can be used against the inventor later as a weapon to demonstrate there was no invention, or at least that the invention had not ripened past the idea stage at the critical moment the invention was memorialized at the time of filing the provisional patent application. Therefore, it is critically important to understand what is required in a provisional patent application and not to fall prey to those who knowingly or unknowingly prey on unsophisticated inventors.

Should I File a Patent Application Before Licensing an Invention? — Without a patent pending you also don’t have anything to license other than an idea that lacks tangible boundaries. While that is not always an impediment to moving forward, the further you can develop your idea the better. The more tangible the more valuable. So an idea is worth something to some people, but an idea that has taken more shape and is really an invention is worth even more. An invention that has been defined in a provisional patent application is worth more, and of course an issued patent takes away much of the risk and questions associated with whether your invention is new and unique. But now we are getting ahead of ourselves. The business of inventing needs to be considered a marathon — not a sprint. Take things one step at a time, proceed deliberately and invest little by little and only so long as it makes financial sense. CLICK HERE to Continue Reading
Justified Paranoia: Confidentiality Before and After Patent Filings — Many inventors will seek to obtain some kind of patent protection so they can stake their claim to their invention. This is a good strategy because when you file a patent application you are articulating your invention and getting on record with a filing date that cannot be taken away from you with respect to whatever is in your patent application. A provisional patent application can be a great first step particularly if you are going to need some assistance later to develop your invention because whatever is disclosed in the application is protected as your invention as of the filing date, assuming of course you ultimately get patent claims issued.
