At first I was surprised to discover there were so many patents related to pillow cases. Then I was intrigued as to quite what was special about this one. But then I was distracted by the wonder of the pillow case which, according to the legally lodged and therefore official and always correct documentation, “may have a width and a length”.
Only “may”.
Not “shall”.
So it may also have no width or length.
Not clear if a height is mandatory or banned.
Either way, that’s some pillow.
Exisential quite possibly.
Or perhaps a manifestation of string theory?
Just in case it holds some quantum trickery, I’m not going to be putting my head down on one of those pillows any time soon.
