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 wor
d 'etc.' may make his statement questionable.
Any additional information that you can offer on this subject will be appreciated.
Thanks,
Dave
