¹Any per­son who has the right to use a com­puter pro­gram may ob­tain, either per­son­ally or through a third party, ne­ces­sary in­form­a­tion on the in­ter­faces by de­cod­ing the pro­gram code us­ing in­de­pend­ently de­veloped pro­grams.

²The in­ter­face in­form­a­tion ob­tained by de­cod­ing the pro­gram code may only be used for the de­vel­op­ment, main­ten­ance and use of in­ter­op­er­able com­puter pro­grams in­so­far as neither the nor­mal ex­ploit­a­tion of the pro­gram nor the le­git­im­ate in­terests of the own­er of the rights are un­reas­on­ably pre­ju­diced.
