If you want to preserve the option to get patent protection for an invention (a new concept and the knowledge of how to implement it), a provisional patent application allows you to preserve your right to seek full patent protection in the future. While full (nonprovisional) patent applications may take months to prepare, provisional patent applications take only weeks or less. They are also cheaper. Provisional patent applications expire after one year, but allow you to file for full patent protection without worrying about lack of patent protection in the meantime.
