Another silly patent

Thirteen years ago, LSI Logic filed for – and it was granted! – a patent on linked lists. I found out about this on Digg.
I wanted to be sure, so I read and re-read the text of their submission, and no matter how you slice it, that’s multiply-linked lists and nothing else.

This patent, unlike another linked-list-related patent, does not add anything to the concept.

OK, so what’s the big deal? Oh, nothing, apparently the patent system has been broken for quite some time now. But that’s not even what I wanted to talk about here. A real silly patent? Mac Donald’s trying to get the sandwich patented! Take a look: http://www.metro.co.uk/news/article.html?in_article_id=26183&in_page_id=34
