Does the one year clock on provisional patent applications start ticking when you submit it, or a few weeks later?

Hey there – this is taken directly from the U.S. Patent and Trademark Office (USPTO) website:

“What You Need to Know [about Provisional Patents:]

Why are filing dates important?

Filing dates set the date for constructive reduction to practice (i.e., the date upon which the invention is disclosed to a patent office as having been made), and in doing so, determine the date against which the invention will be tested for novelty and non-obviousness. How? Unless an inventor files evidence that his/her invention was actually made earlier than an application filing date, the filing date serves as the date before which publications, public use, and sales may serve as “prior art” against the invention.”
