I go to the store and I see many knock offs of name brand items that look and taste just like the original. Sometimes even the box look a like. This also goes for toys, phones, cars etc. Whats the point of having a patent if someone can change a small ( really small ) feature and say its new? I'm suppose to spend thousands of dollars and can still get people bring my idea to market!
I kind of feel that here in the u.s the monopoly laws kinds of go against the patent theory. If I make a brand new product and get a patent so no one can steal it then I'm in a sense a monopoly. But if people can still take my idea then patents are useless.. I'm sure there's a reason but what is it?
