To cope with the increasingly severe market environment, continuously improve independent innovation capabilities, and increase investment in intellectual property, the company invited Zhang Kehua, Deputy Director of Tongling Intellectual Property Bureau, to give a lecture on "Basic Knowledge of Patent Law" on March 9, 2009. He used rich theories and vivid examples to explain the overview of the patent system and patent law, the conditions for granting patent rights, patent rights and their protection periods, and how to apply for patents. The entire report is focused on key points, rich in content, and thorough in analysis. It is both theoretical and actionable, and has a good promoting effect on our company's better development of patent creation, application, protection, and other work. The relevant units of the company, production plant technicians, equipment, and quality management personnel attended the lecture in person.
