Provisional Patent Application
Provides patent pending status for up to 1 year, a provisional patent application is a great way to lock in your idea without initially spending a lot. They can be filed informally, without adhering to the strict formatting of non-provisional applications, so long as they convey the concept completely. However, the inventor will not receive any feedback from the USPTO and the inventor will not find out about a deficiency until years later when it is too late. Thus, the inventor needs help knowing what is relevant to include and what is not. A provisional patent application only applies to a utility patent application.
