Is an Adobe Acrobat PDF a TPM?
The answer to this question will depend on the specific facts of each case. While PDF software might often be used to enable access by users of many different kinds of hardware, and therefore be promoting broad access, it could also be used potentially to block certain access. Answering this question will determine whether it is being used as a TPM. If it is being used as a TPM, circumventing its operation will amount to using a circumvention device, and any copying or communication of the material accessed could be found to be an infringement of copyright.
