§ 17 para. 1 UWG refers to the disclosure of secrets by employees during a persisting employment relationship.
§ 17 para. 2 UWG, which years ago was considerably extended by the second law against white collar crime, includes – particularly with regard to modern data processing – in figure 1 some typical occuring acts considered as particularly dangerous, which comprise the danger of an unauthorized utilization and disclosure of other person's secrets. According to figure 2 the unauthorized utilization and disclosure of other person's secrets dishonestly obtained by the offender will be prosecuted.
§ 18 UWG refers to the unauthorized utilization of technical instructions entrusted to the recipient.

However, attention has to be paid to the fact that, although these norms are part of the law against unfair competition, they do not only imply competition situations. §§ 17 und 18 UWG are intentionally shaped as penal provisions and can also be applied in the cases of some other motives for crime. These regulations become effective in terms of civil law, primarily through § 19 UWG, § 823 para. 2 BGB and – as far as the offender acts for the purpose of competition – through § 1 UWG.

Generally the protection of secrets represents an alternative to (registered)-industrial property rights. In the most cases however, it can not be realized for practical reasons, especially if products placed at the market can be analyzed and reproduced by third persons - even if it may require a certain effort.
