Patents and copyright work quite differently and patents aren't really appropriate for software. Patents allow you to be too granular in what you protect to make sense for software. I think a good comparison would be protecting combinations of two musical notes in music. This would dramatically impact creation of new songs because you are protecting something too trivial. The equivalent happened when software patents first were introduced.

I feel like you're attacking our specific implementation of patents (and especially software patents) in America. I'm talking about the idea of copy protection. Is it an incorrect assertion that in a world without any copy protection, people would be free to copy any invention they wanted? Thus, the original inventors' version of the product (which would be exactly the same as the copied version) would have no differentiating factors, and there would be no guarantee of profit from invention.

Yes, there are a lot of flaws in copy protection. There are a lot of instances where patent trolls and patents are detrimental to innovation.

But the main point that I was originally making was: Wouldn't a world without copy protection be a world where every invention gets literally copied, resulting in lesser gains for the actual inventors?

I think you may have misunderstood me: I did not mean to support software patents or our current implementation of software patents at all. Instead, I was countering the gp assertion that (patents are rare in the software world + software world doesn't have rampant issues with ripoffs) implies that patents are not necessary to profit off of inventing. My counterargument was that the software world may not have many patents, but it does still have copyright, and thus their counterargument does not invalidate my overall point/question: "copy protection is necessary in order to not have a world full of ripoffs"

Yes, that's a very different point that I mostly agree with. In addition the secrecy that also gets caused by rampant copying also would be/was a massive issue and was the driving force behind the introduction of patents. Of course patenting "XOR" and protecting the stupid mouse forever are a totally different issue as you pointed out.
