I think that's quite off-topic for the submission at hand, however. The article has little (nothing?) to do with intellectual property (other than perhaps copyright and authorship of Myrvold's upcoming book) or patents.
If you want to consider this as a reason to discount the submission, please feel free. Perhaps even flag the submission if you feel it's inappropriate for HN. But please don't derail what could otherwise be an interesting conversation about bread, physics, and the history of cooking.
