PROVISIONAL WINDOW

The 12 months after filing

A provisional establishes a filing date and allows “Patent pending” for 12 months. It is not examined and does not become a patent by itself.

The calendar file includes a separate all-day entry and the first deadline alarm.

COMMON QUESTIONS

Questions about preparing and filing

Is PatentSieve legal advice?

No. PatentSieve is not a law firm and does not give legal advice.

What does a provisional application give me?

A provisional application gives you a filing date and lets you say Patent Pending for 12 months. It is not examined, does not become a patent by itself, and covers only what it describes.

Does PatentSieve file with the USPTO for me?

No. You file the provisional through USPTO Patent Center or give the package to a registered patent attorney or agent.

What happens after 12 months?

To keep the provisional filing date, you must file a non-provisional application within 12 months. Inventors usually work with a registered patent attorney or agent on that application.

Who can see my invention?

An invention is private to its creator. Teammates can open inventions created on their team, and AI steps and searches send the text they work on to the services that run them.

Can a patent attorney review my work?

Yes. You can download an attorney packet and contact one registered patent attorney or agent through the practitioner directory. PatentSieve verifies USPTO registration but does not recommend or rate practitioners.
