So I was reading an article about a patent dispute and learned that US patent law has changed. Am I reading this right? Being an inventor of something no longer means they are the patent holder... rather they have to file it?
The way it's described sounds like I could just pick something off the internet which someone had intended to make public domain and patent it... Is that correct? Do we have to patent something first if we want it to be public domain? Doesn't that add expense? Should they make it free since the invention is intended for the public domain? Seems like a burden is being created for those who just want the world to have it.
