239. Decompilation of computer program by lawful user

the program is expressed in a low‑level language;

X is a lawful user of the program;

the decompiling is necessary to obtain the information needed for the purpose of creating an independent computer program that can be operated with the decompiled program or another computer program;

the information needed for that purpose is not otherwise readily available to X;

X confines the decompiling to acts that are needed for that purpose;

X does not use the information obtained from decompiling for anything other than that purpose;

X does not supply the information obtained from decompiling to any person unless it is necessary for that purpose;

X does not use the information obtained from decompiling to create a computer program that is substantially similar in its expression to the decompiled program; and

X does not use the information obtained from decompiling to do any act that is an infringement of copyright.

converting the computer program into a version expressed in a higher level language; or

copying the computer program incidentally in the course of paragraph (a),and “decompile” has a corresponding meaning.
