What if I miss the 12-month deadline?

The application is deemed abandoned; there is limited scope to post-date, but generally a fresh filing is required.

Can a provisional be granted as a patent?

No — it must be followed by a complete specification, which is what proceeds to examination and grant.

Overview

Understanding Patent Provisional Registration

A provisional specification secures the earliest possible filing — your priority date — for an invention that is still being developed. It is the strategic first move: it stakes your claim, deters intervening third-party filings, and buys 12 months to refine the invention, run trials and raise funding before committing to the complete specification. Within those 12 months, a complete specification must be filed claiming priority; if it isn’t, the application is deemed abandoned. We draft a provisional that substantively discloses the invention (so the priority is solid), file Forms 1 and 2, and then prepare and file the complete specification — including using the provisional date as the basis for foreign filings under the Paris Convention or PCT.

Costly errors we routinely help clients fix — or better, avoid altogether.

Thin Disclosure

A provisional that under-discloses cannot support the later claims, weakening priority.

No complete specification within 12 months means the application is abandoned.

Disclosing Before Filing

Public disclosure before the provisional can defeat novelty.
