Math teachers can no longer use f(x)?

Someone I work with pointed out that a recent clothing
line by Lands' End uses f(x) for its registered trademark,
and she was wondering (facetiously) whether math books,
math teachers writing on blackboards (or whatever they
do nowadays), students, and the like will have to pay
royalties to use f(x). Maybe the days of f(x) being the
first notation choice for a function are behind us, and
from this point on it will be g(x)?
