Can a user modify a typeface using font manipulation software such as Macromedia Fontographer (formerly Altys Fontographer)?
Customers are allowed to use font manipulation software to produce “derivatives” of typefaces licensed from Adobe, as long as they use the derivatives in accordance with the same licensing terms that are stated on the packaging for the original Type 1 products. For instance, it is legal to use Fontographer to convert a Type 1 typeface from Adobe into TrueType format for individual usage, but it is strictly illegal to assume ownership of the derivative TrueType typeface and to sell it or give it away. Derivative works are definitely protected under copyright law, and Adobe will pursue its property rights vigorously.
