The DMCA Exemptions for 2015 were announced by David S. Mao, the Acting Librarian of Congress, and effective as of October 28. This is a series of exemptions allowed every three years upon review. There is now a limited exemption for jailbreaking software in cars, 3D printers, phones, tablets, other portable devices, games, and allowance for the use of excerpted DVD clips for educational use. Some of the items on the list, such as limited use of DVD excerpts had been approved in last reviews. The process requires a renewal to prevent the exemption from expiring.
I often found the refusal to exempt making archival copies of DVDs a bit hypocritical as there are quite a few software packages that can accomplish this for sale on large commercial retail sites. And then there are stories such as a review of the Five Best DVD Ripping Tools from Lifehacker. Let me state up front that I am not encouraging anyone to violate copyright law. I’m merely pointing to examples that show how little the prohibition against copying/ripping seems to be enforced. Maybe this software is bought mostly by academics for classroom use.
