Patent law: study the exam guide and read more books. This book is very important.
Related laws: read the book outline and exam guide every year.
Practicality: case analysis of recommending Wu Guanle to write patent application documents for invention and utility model.
In addition, I recommend teacher Yang Minfeng's exam collection, which is also a very good reference book.
Among other materials, you can find recordings and videos, which can be found in Himalaya and Youku. In addition, you can find a special intellectual property examination system, which is more comprehensive.
