- lucozade 11y agoJust goes to show that sometimes innovation and entrepreneurship don't go hand in hand. Just search for cat vs laser pointer on Youtube. There's a ready made mint right there.
- jordigh 11y agoPublic domain is for copyrights, isn't it? Patents are always public. That's their whole point.
- WildUtah 11y agoA patent is in the public domain until it issues and after it expires. It just means the patent is not yet or no longer in force and therefore the subject matter is not restricted. 'Public domain' has nothing to do with being secret or readable by the public either in copyright or patent; it's a matter of freedom to use or copy.
