Ezra Klein finds a more apt, but still imperfect, comparison:

You can’t patent dessert. Just ask Jean-Georges Vongerichten. Years ago, he created a chocolate cake with a molten core of liquid chocolate. The recipe became a sensation. Which meant it appeared on menus all across the country, with no credit to JGV. That’s a bummer for its creator, but a boon to all of us who don’t live in New York. We get to eat it anyway. And yet innovation continues apace in the food world.
