.  Read the following facts:  As if the cloud looming over the Olympic
Games wasn't large enough, yet another potential legal problem may
help to darken it even further. A new lapel pin poking fun at the
Olympic bid scandal has been temporarily pulled off the market. The
creator and seller of the pin, has been asked to cease the sale and
distribution of the pin so as to avoid a potential lawsuit.
The pin features cartoon images of five prominent officials (of the
city hosting the Olympics) on coins that are lined up in shapes
resembling the five Olympic rings. An attorney has asked that he stop
selling the pin because it features the phrase, "The Best Games Money
Can Buy."
The plaintiff claims that it had registered the phrase "Best Games $$
Can Buy".
Assuming the registration is proper, fully explain the best legal
defense that the defendant could raise, if sued for some form of
intellectual property infringement.  Cite and discuss a similar case
you found on the internet (doesn’t need to be case law, can be from an
internet article link) which utilizes a similar defense.
