A recent article on online patenting is very intrigued by the simple and easy way to inexpensively file an application for an invention. However, the thought did not give rest: “Too good to be true,” - and I had to turn to the original source ( Provisional Application for Patent ). I cannot but agree with PDmitriy : preliminary application is a great way to claim your rights. However, there are pitfalls that are not obvious at first glance.
A preliminary application determines the official filing date; This date is a weighty argument in proving its priority.
Established in United States patent application filing date for the invention;
A preliminary application gives the right to officially use the term “Patent pending” during the year. (Now it’s clear from where this “patent pending” domination of technologies from dubious firms :)
Permits 12 months of authorization to use "Patent Pending" notice in connection with the description of the invention;
Preliminary applications are not considered on the merits. (You can write anything, which, apparently, is used by the above mentioned firms.)
Provisional applications are not examined on their merits.
A preliminary application makes it possible to “stake out” the invention for a small fee in order to assess its market potential and decide whether to spend money on a full-fledged patent.
It has been noted that it will be possible to make a decision on how to apply for a patent.
Unpleasant
Within 12 months after making a preliminary application, you must either submit a “non-provisional” application or convert your provisional one into it.
Issuance of a patent (Patent Post-Allowance Fees): $ 430 ... $ 755.
Content of the patent (Patent Maintenance Fees): $ 490 (in 3.5 years), $ 1240 (in 7.5 years), $ 2055 (in 11.5 years).
Inventors should be fully aware that a preliminary application will not become a patent without additional documents. Some firms for the "promotion" of inventions misuse the idea of ​​preliminary applications, in essence leaving authors without a patent.
Inventory should not be accepted. Filing companies misuse the provisional application process.
Disclaimer : I have nothing to do with patent cases, “what I read, about that and I sing” - with quotations as confirmation. If someone is professionally engaged in patent law - I will be happy with the amendments.
