There is a similar but less restrictive exemption in Europe, specifically aimed at permitting interoperability. https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX%3A32009L0024 https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX%3A... On the other hand, it contains some traps that can be used to put some limits back in, such as the last lines here: (emphasis mine) "(15) The unauthorised reproduction, translation, adaptation or transformation of the form of the code in which a copy of a computer program has been made available constitutes an infringement of the exclusive rights of the author. Nevertheless, circumstances may exist when such a reproduction of the code and translation of its form are indispensable to obtain the necessary information to achieve the interoperability of an independently created program with other programs. It has therefore to be considered that, in these limited circumstances only, performance of the acts of reproduction and translation by or on behalf of a person having a right to use a copy of the program is legitimate and compatible with fair practice and must therefore be deemed not to require the authorisation of the rightholder. An objective of this exception is to make it possible to connect all components of a computer system, including those of different manufacturers, so that they can work together. Such an exception to the author's exclusive rights may not be used in a way which prejudices the legitimate interests of the rightholder or which conflicts with a normal exploitation of the program."
