Yes. That's why there are some knock-off fonts that is fully legal in the United States (apart from the name, but that's trademarks).

Note: US law (for rather obvious reasons). Europe (depending on the country) has either a design trademark or a design copyright available, which means that foundries can (in theory) control their use there (in practice, uniform worldwide licensing means they go for the lowest common denominator). Asian (mainly East Asian) IP laws does have a nuance, which means that whether a design is copyrightable depends if the purpose of the said design is utilitarian or artistic.
