In order to cope with the increasingly severe market environment, the company constantly improves the ability of independent innovation and increases the investment in intellectual property. On March 9, 2009, the company invited Zhang Kehua, Deputy Director of Tongling Intellectual Property Office, to give a lecture on "Basic Knowledge of Patent Law". With rich theories and vivid examples, he explained the overview of patent system and patent law, the conditions for granting patent right, patent right and its protection period, and how to apply for patent. The whole report is prominent, rich in content and thorough in analysis. It is both theoretical and operable, which has a good role in promoting the creation, application and protection of patents in our company. The company's relevant units, production plant technology, equipment, quality management personnel and so on attended the lecture.
