Doesn the DMCA allow reverse engineering for compatibility, for example to allow playing of a DVD on a Linux operating system-driven personal computer?
The DMCA does allow reverse engineering. However, the reverse engineering provisions in the DMCA were never intended to enable anyone to circumvent technical protection measures (TPMs) for the purpose of gaining unauthorized access to or making unauthorized copies of copyrighted works. The DMCA does allow a lawful user of a computer program to circumvent TPMs to ensure that the program can work with other programs (interoperability); and, with strict limitations, the research may be shared with others, as long as it does not infringe the copyright in the original or a related work. However, reverse engineering is not permissible if there is a readily available commercial alternative for that purpose. In this case, there exist MANY commercially available DVD players.
