The term of a patent is the maximum time during which it can be maintained in force. It is usually expressed in a number of years either starting from the filing date of the patent application or from the date of grant of the patent. In most patent laws , annuities or maintenance fees have to be regularly paid in order to keep the patent in force. Thus, a patent may lapse before its term if a renewal fee is not paid in due time.
Consequently, in most patent laws nowadays, the term of patent is 20 years from the filing date of the application. This however does not forbid the states party to the WTO from providing, in their national law, other type of patent-like rights with shorter terms. Utility models are an example of such rights. Their term is usually 6 or 10 years. The European Patent Convention requires all jurisdictions to give a European patent a term of 20 years from the actual date of filing an application for a European patent or the actual date of filing an international application under the PCT designating the EPO.

Priority date refers to the earliest filing date in a family of patent applications. Where only a single patent application is involved, the priority date would obviously be the filing date of the sole application. Known as the priority application, the earliest patent filing may comprise a provisional patent application, a non-provisional patent application or a foreign application. The term may also refer to the earliest filing date of a particular feature of an invention.
The priority date is how we determine whether another patent filing or publicly available document qualifies as prior art against your patent application. Basically, each feature has a priority date of when it was first filed. Since the USPTO operates under a first-to-file rule, maintaining the earliest possible priority date is preferable. If a priority date can be maintained, then by implication it can also be lost particularly when a patent family is involved. One of the most common ways to forfeit a priority date is the failure to convert a provisional to a non-provisional within one year from the provisional filing date.
Re-filing the provisional results in a later priority date, which consequently opens up potentially more prior art that can be used against you. For international and foreign applications, such foreign filings generally must take place within one year of the US priority date unless a PCT application is timely filed to extend the deadline for national applications to be filed in each individual foreign country.
