Note that this decision, while narrowly overturning a summary
judgement by a lower court, also discusses the elements of
architectural copyright in general. (Unfortunately the end notes are
missing from the on line copy.) Also note that design elements can
clearly be copyrighted.

Thank you, Professor Cook.

I suggested a recipe or bricklaying pattern as an obvious example of
something utilitarian that would be copyrighted to death if it were
possible. You cite instead a case involving a architect's designs for
phallic symbols decorating a building. I await your citation of something
utilitarian that is copyrighted.
