Notes:
Quote: The public disclosure of a new idea stops others from patenting it. However, a patent application must be applied for within a year of the public disclosure.
Dave, I'd say you are wrong here. Only the first part is correct.
forget,
The primary objective is to stop the ideas from being patented. This way all can freely use these basic ideas. However, an individual still has the ability to patent related or subordinate ideas, which he/she develops.
The second part of your posting could be a concern for 'open group inventions'.
The following is from a patent lawyer. "In Canada and the United States, you may still apply for a patent if such public use, sale, disclosure, etc. occurred no more than a year ago, and if a patent application can be prepared and filed within a year of the first such public use, disclosure, sale, etc."
The fact that he uses the word 'etc.' may make his statement questionable.
Any additional information that you can offer on this subject will be appreciated.
Thanks,
Dave

I'm right - and I'm wrong, depending on which side of the Atlantic you're sitting. The US has unilaterally gone sideways on this, despite Patents being very much an International thing.

Provisional Application for Patent Filing Date Requirements
The provisional application must be made in the name(s) of all of the inventor(s). It can be filed up to 12 months following the date of first sale, offer for sale, public use, or publication of the invention. (These pre-filing disclosures, although protected in the United States, may preclude patenting in foreign countries.)
Such as the rest of the world.
