It's been a long time since, but as far as I remember it basically boils down to pasting the pfa into your file (pfb2pfa is your friend here).

Fonts in the abstract may or may not be copyrightable depending on where you live, but the actual pfa-code you put in your file and the representation generated from that when converting to PDF definitely are.
