Risks of Filing Provisional Patent Applications

The United States has a form of patent application called a Provisional Application for Patent (PAP). A number of people feel that these are an trouble-free and economical way to acquire a filing date and some patent rights, but they are as a rule uninformed of the risks and disadvantages.

These patent applications never emerge into a patent, and can in no way be enforced to restrict someone from copying your invention. If a regular, complete, patent application is formulated and filed within a year from the filing date of the provisional patent application, the regular patent application may be designated to the filing date of the provisional patent application, but only if the provisional application meets best mode and enablement requirements.

In order to be legitimate, the provisional patent application must stay in line with the first paragraph of section 112 of the patent law. If the provisional application does not stay in line with this section, it will be unacceptable and will not accommodate a filing date. As the U.S. Patent and Trademark Office does not inspect these applications, it may not become noticeable that a provisional application is unacceptable until after the deadline for filing a patent application has expired. It ought also be considered that provisional applications routinely expire twelve months after filing, and that this deadline is important, and is not extendible. Foreign applications are required to be filed within one year of the filing date of the provisional application in order to be accredited to the filing date of the provisional patent application. Thus, a disadvantage of a PAP is that there is no opportunity to receive a first diagnosis by the U.S. Patent and Trademark Office previous to making the determination of whether or not to file interrelated foreign applications.

If provisional patent applications are used, it is suggesed that they be drafted as if they were a full conventional patent submission to make sure that they adhere with the best mode and enablement requirements. An unacceptable patent application has absolutely no value. A patent infringement trial normally costs over a million dollars in legal fees and it is not sensible to skimp on costs for the duration of the patent drafting course of action. With such prominent stakes, a qualified litigator is looking for every imperfection in a patent application. A provisional patent application that is not planed by a patent attorney is likely to have plenty of obstacles. These predicaments will pass on through even if a patent attorney is soon after hired to design a regular patent application. This is because the "file history" of the patent application will be ordered and the provisional patent application will be obtainable along with the file history.

Various blunders that can be made in drafting a patent application are illustrated in my handbook on how to find a patent attorney.

For instance, if an applicant in a provisional application says "the switch is a MOSFET" where no given type is vital, and then a patent lawyer preparing a conventional patent application corrects this by saying "there is a switch, it can be any type but in various embodiments it is a MOSFET", be prepared for an argument during litigation that unless a competitor uses a MOSFET, there is no infringement in spite of what is recited in the statements since the inventor undoubtedly only contemplated service of a MOSFET.

If there is no financial plan for a complete application and a provisional application is filed, a full application planed by a patent attorney ought to be filed as soon as viable after the provisional application is filed. Thus, as long as that the provisional application does not stay in line with the provisions of 35 U.S.C. ' 112, first paragraph, it may be doable to prepare the conventional application earlier than any important deadlines are avoided.

Keep in mind that it usually takes three or more months for a patent lawyer to make ready an actual U.S. Patent application, depending on workload. Therefore, if you file your own provisional patent applications, do not hang around until the end of the one year interlude to decide if you want to carry on with a conventional patent application. Because of changeable caseload demands and other matters, law firms usually maintain the right to turn down to take on work for any reason. Furthermore consider that the provisional applications automatically expire one year after they are filed. Nobody will be reminiscent you of the time limit for filing an tangible patent application. No additions of time are obtainable.

With these risks contemplated, provisional patent applications that are not drafted as full regular patent applications can still be beneficial for attaining "patent pending" status if there is simply no financial plan for a complete patent application.
