When dealing with a defendant who leaked trade secrets, if you want to explain that the defendant's actions were intended to promote competition and innovation in the industry in order to seek a lighter penalty, you can consider the following points: 1. **Emphasis on the necessity of innovation**: Argue that the defendant's actions were intended to promote technological progress and innovation in the industry. You can provide data or cases to illustrate how competition and technological innovation can promote the overall interests of the industry. 2. **Prove the purpose of the behavior**: If you can prove that the defendant's actions were in good faith, such as to develop new products or services, rather than for personal profit or malicious competition, this will help reduce his liability. 3. **Industry background analysis**: Provide the industry's general views on competition and innovation, showing that in some cases, the act of obtaining trade secrets is regarded as a normal phenomenon in the development of the industry, rather than just illegal. 4. **Positive impact of the consequences of the behavior**: If the leak has brought about positive changes in the industry, such as improving industry standards and promoting innovation in other companies, this can be used as a reason to reduce the penalty. 5. **The limit of legal competition**: Explain the boundary between leaking and legal competition, indicating that the defendant may not realize that his behavior has exceeded the acceptable range of the industry, and emphasize his good reputation in the industry. 6. **Repentance and remedial measures**: Demonstrate the defendant's change of attitude after realizing his mistakes, such as willingness to take measures to remedy or apologize, and willingness to negotiate with the affected parties and flexibly resolve the problem. 7. **Expert witness support**: If possible, invite industry experts or economists to testify to support the defendant's position and explain that his behavior is promoting innovation to some extent. Through the above strategies, combined with sufficient evidence and clear logical arguments, it is possible to win the defendant a chance to reduce the punishment.
