There's a point to the information presented in this story, so read on! :lol:
Interestingly enough, per the US Copyright Office circa 1989-1990, there is no copyright extended to "font data," only to the software for using a "font."
For a period of about nine months, there was no copyright protection AT ALL for computerized fonts. Based on the earlier precedent that no company could claim to "own" the Alpha-Bet, computer font providers found themselves in the same boat as actual printing press type manufacturers. They also had claimed copyright on their versions of typeface families (collections of sizes, weights, italics, swashes and dingbats are technically called "fonts,") and were shut down in their attempt to tie their printing press user base to their own fonts.
This decision came down during the period I was ramrodding the development of a ROM Emulator based "Font Emulator" for a specific vinyl letter cutting CAD/CAM system. When I read about this decision, I told my original partner that we were way behind schedule for development and release of the product, which alas, never got past the initial production run. We did get a really nice mention in one of the trade mags for our, until then unheard of, policy of not releasing the product until it actually worked as claimed, as opposed to the rest of the vertical market CAD-CAM equipment providers.
Be that as it may, Adobe et al, hounded the Copyright Office in the courts until the above compromise was reached. After spending way too much of our development capital on inconclusive Intellectual Property Advice, we folded up the company. Dealing with the inevitable lawsuit with a manufacturer who claimed "code based" protection on "fonts," which we knew and could certainly prove contained data only was a losing proposition for a shoestring technology development company.
The point of this little story would be that PostScript "fonts" do, indeed, consist of PostScript language descriptions of typefaces, but the actual Bezier path and bitmap data were determined to be copyright free. So the use of Fontographer to tweak data imported from PostScript "fonts" can be considered entirely legal in terms of copyright. You might want to check for UA violations, but I don't recall this ploy being used by type companies until well after the protection of the "font" data was voided by the copyright office.
So: read . . . determine . . . play! [}
