The filing fee is generally lower than a non-provisional application fee.

Why File a Provisional Patent Application?

A provisional patent application offers an early priority date. The early priority date secures the invention's position in the patent queue. The early priority date prevents others from patenting the same invention later. A provisional patent application provides a "patent pending" status. The "patent pending" status deters potential infringers. The "patent pending" status adds credibility to the invention. A provisional patent application gives inventors more time. The extra time allows for invention refinement. The extra time allows for market evaluation.
A provisional patent application allows for testing market viability. Testing market viability helps determine commercial potential. Testing market viability informs investment decisions. A provisional patent application offers a lower initial cost. The lower initial cost reduces financial risk for early-stage inventions. The lower initial cost allows resources for development. A provisional patent application preserves patent rights for foreign filings. Foreign filings must occur within twelve months of the provisional filing date.

How Does a Provisional Patent Application Secure a Priority Date?

A provisional patent application secures a priority date on the filing date. The filing date establishes the invention's earliest documented existence. The earliest documented existence provides a defence against prior art. The patent office records the provisional patent application's filing date. This recorded date serves as the official priority date. Subsequent non-provisional applications claim this priority date.
The priority date prevents later inventions from invalidating a patent. The priority date protects an invention from subsequent public disclosures. Public disclosures by the inventor after the provisional filing date do not count as prior art. The provisional patent application adequately describes the invention. The non-provisional application claims the invention described in the provisional application. The provisional application's disclosure supports the non-provisional application's claims.

What are the Limitations of a Provisional Patent Application?

A provisional patent application does not mature into an issued patent. A provisional patent application only holds a place in line. The provisional patent application requires a non-provisional application for patent issuance. A provisional patent application provides no enforceable patent rights. The invention has no legal protection against infringement during the provisional period. Enforcement only begins after a non-provisional patent issues.
A provisional patent application has a strict twelve-month expiry. The twelve-month expiry means a non-provisional application must file within that timeframe. The twelve-month period is not extendable. Failure to file a non-provisional application within twelve months results in abandonment. The invention loses its priority date upon abandonment. The inventor must start the patent process anew.

What Happens After a Provisional Patent Application is Filed?

The filing receipt confirms the application's submission. The filing receipt indicates the official priority date.

The provisional patent application remains pending for twelve months. During this twelve-month period, the inventor develops the invention. During this twelve-month period, the inventor prepares a non-provisional application. The non-provisional application must claim the benefit of the provisional filing. The non-provisional application must include formal claims. The non-provisional application undergoes examination for patentability.
