transferee of such product engages in any of the foregoing acts if the transferee is not aware, without gross negligence, that the product was produced through such improp -

er use of a technical trade secret. 2.2 Employee Relationships

An employment relation is generally understood to impose certain inherent obligations upon the employee, whether explicitly provided in the employment contract or not. One of such duties is the fiduciary duty, or duty of good faith, which requires the employee to avoid unjustly harm - ing the interests of the employer. Obligations to keep the employer’s business secrets confiden - tial and non-competition obligations are a part of this fiduciary duty, and the breach of such duty would constitute a breach of the employment contract. Information of the employer may be protected under this regime, even if it did not satisfy all of the elements of the trade secrets described in 1.2 What Is Protectable as a Trade Secret . 2.3 Joint Ventures The UCPA does not provide any specific rules

focused on joint ventures. 2.4 Industrial Espionage

The UCPA does not provide any specific claims or remedies focused on industrial espionage. However, acts of industrial espionage are broadly captured under the misappropriations described in 2.2 Employee Relationships .
