you are talking about a company that tried to argue a "tap" is a "zero length swipe"

Judging by a recent order with Deliveroo (when I was told I couldn't order chips/fries because they haven't figured out how to reliably deliver them), it's a licensing play.

Could be solely defensive. Maybe the food container biz is highly litigious.

Would that patent really hold? It's just a round box with 8 holes!

So now (well since 2012), if someone makes a box with holes, it's breaking patent law? I thought only software patents were ridiculous

It's a needlessly complex expensive design that only apply would want: https://www.google.com/patents/US20120024859

Because then you can use it as a bragging point.
