Are you declaring that there are copyright doctrines more restrictive than the US?
For copyright specifically (not IP in general, and definitely not patents), the US is very soft.
For instance many mainland euro country have a concept of Author's Rights (or moral rights), which may well be perpetual, inalienable, unwaivable and unassignable (in a company, the moral rights belong to the employee who created the work, the company has an exclusive license to the economy rights of the work). In french law, moral rights provide 4 sub-rights:
* divulgation right, the author is sole holder of the right to decide the original disclosure of the work
* paternity right, respect must be given to the parental relation between the author and the work
* work respect right, the author can forbid any and all transformative work. This alone means "fair use" is much, much broader in the US than in France
* repent right, even after divulgation the author can "uncirculate" the work (although he may have to compensate license holders)
and because these moral rights are perpetual and inalienable, you can't put something in the public domain in France, you can only provide a universal license. The work will only fall in the public domain once copyright has expired.
