I do not believe any software should be patentable.
I also don’t think any action done in software, a virtual world, or even physically done in a different setting than previously performed, should be patentable.
In other words, starting a restaurant on the Moon should not create new patent opportunities.
I believe that it should.
Just never copywritable under any circumstances.
I don’t believe in zero intellectual property protection for code, just not lifetime plus seventy years worth of protection.
