There's also SCMS, which is technically similar (just two bits). Reputable vendors sell devices which manipulate these bits. For example, the Behringer Ultramatch Pro SRC2496 manual says, “Allows direct manipulation of emphasis and copy-protection bits” (although they also say that, “We want to point out that the copyright of third parties must not be infringed—despite the possibility of removing the copy protect bit with the help of the ULTRAMATCH PRO! This device was not developed to produce unauthorized copies”). This is more similar to the ttfpatch case because it allows other devices to operate in a way contrary to their design.
