Edward Felten, head of the ACM's special interest group on DRM, petitioned the Library of Congress for an exemption in order to circumvent access control mechanisms for research purposes. Felten discusses how the evolution of technology is dependent on past improvements. By restricting researchers from experimenting with copy protection methods, improvement to techniques will be hindered. He demonstrates the negative impact by discussing the paper he wrote comparing different methods of breaking protection and what information is required to crack the protection, something the record companies tried to prevent from being released with the DMCA. Felton also claims that in the field, it is unclear in the early stages of research whether a possible DMCA violation will be incurred or not. Academics are unlikely to engage in research that could potentially lead to violations, hindering not only research directly related to DRM, but tangential applications as well.

The most important thing to come out of the exemption request is the context in which research is given. In describing the valuable research he participated it in before the DMCA was enacted, Felten notes that the SDMI sponsored his acclaimed research paper on breaking access control methods. The SDMI is a group of music distributors, and had something to gain from their studies, and now sought to prevent others from sharing in this knowledge. Clearly, by inhibiting research into access control, the technology of copyright protection and the lessons learned from the research falls solely in the hands of the gatekeepers, the record companies. Without the added input of the academic community, research in the field has been hindered and copyright holders have not been provided the best digital protection methods.

The best example of his hindered research is the Sony Rootkit debacle. He and an associate discovered the vulnerability but had to delay publication and hire a lawyer to make sure that they weren't exposing themselves to DMCA violation. Threats of DMCA violations prevent important studies and important information from reaching the consumer.
