What is the difference between a full patent and provisionary patent?

There are two types of utility patent applications, a regular application, which gets examined and hopefully eventually becomes a patent, and a "provisional" application which never becomes a patent but can become the basis for a regular patent application if one is filed within a year of the provisional filing date. After you apply for a patent, whether provisional or regular, you can mark your product and advertising as "patent pending." It may scare off some potential infringers or it may not. However, you have no legal enforceable rights until a patent issues (with the exception that it is possible for damages to accrue from the publication date of a regular patent application in limited circumstances). You can either file a provisional application or a regular utility application up front. However, there are many dangers with filing a provisional application unless it is drafted as if it were a full regular patent application. In order to be valid, the provisional application must comply with the first paragraph of section 112 of the patent law. If the provisional application does not comply with this section, it will be invalid and will not provide a filing date. As the U.S. Patent and Trademark Office does not examine these applications, it may not become apparent that a provisional application is invalid until after the deadline for filing a patent application has passed. It should also be kept in mind that provisional applications automatically expire one year after filing, and that this deadline is not extendible. Foreign applications must be filed within one year of the filing date of the provisional application in order to be entitled to the filing date of the provisional application. Thus, a disadvantage of provisional applications is that there is no opportunity to receive a first examination by the U.S. Patent and Trademark Office before making the decision of whether or not to file corresponding foreign applications. If provisional applications are used, it is recommended that they be drafted as if they were a full regular patent application to make sure that they comply with the best mode and enablement requirements. An invalid patent application has zero value. A patent infringement trial typically costs over a million dollars in legal fees and it is not wise to skimp on fees during the patent drafting process. With such high stakes, a professional litigator is looking for every weakness in a patent application. A provisional application that is not drafted by a patent attorney is likely to have many problems. These problems will carry through even if a patent attorney is later hired to draft a regular patent application. This is because the "file history" of the patent application will be ordered and the provisional patent application will be available along with the file history. Various mistakes that can be made in drafting a patent application are described in my guide on how to find a patent attorney. For example, if an applicant in a provisional application says "the switch is a MOSFET" where no specific type is essential, and then a patent attorney preparing a regular patent application corrects this by saying "there is a switch, it can be any type but in some embodiments it is a MOSFET," be prepared for an argument during litigation that unless a competitor uses a MOSFET, there is no infringement regardless of what is recited in the claims because the inventor clearly only contemplated use of a MOSFET. If there is no budget for a full application and a provisional application is filed, a full application drafted by a patent attorney should be filed as soon as possible after the provisional application is filed. Thus, in the event that the provisional application does not comply with the provisions of 35 U.S.C. ' 112, first paragraph, it may be possible to prepare the regular application before any important deadlines are missed. It should be kept in mind that it usually takes thre

A provisional application differs greatly from a full utility patent application. Basically, a provisional application is an incomplete utility patent application. Although a provisional application grants you "patent pending" status upon filing, it is not reviewed by the USPTO and merely grants you the ability to obtain the earlier filing date of the provisional if you file the full utility application within 12 months of the provisional date. There are certain circumstances in which a provisional application may make more sense to file rather than an utility patent application but it is strongly recommended that you consult with a patent attorney to weigh your options. If all the necessary information is there, I typically advise my clients to just proceed with the full utility patent application filing rather than delay things with a provisional application.
