1. Read the patent law, detailed rules, and examination guidelines. It doesn’t matter if you don’t understand them. It is mainly used to familiarize yourself with some professional terms and general contents. 2. Watch the teaching videos on the Juice Bureau’s website. There are ready-made ones, and it will be easier to understand through the teacher's explanation. This part is more time-consuming, but if you can listen patiently to the end, you will definitely gain a lot. 3. Do the questions like crazy, Yang Li’s real question set, do the past exam questions once, you can do it while looking at the answers the first time, and you can do it yourself and get the answers right the second time. 4. Copy the answers to practical questions and memorize commonly used regulations, rejection clauses, invalidity clauses, etc. In the professional examination, the characteristic of "patent legal knowledge" is "deep". Some basic concepts in the patent system, such as novelty, creativity, practicality, unity and other concepts, must be deeply understood and mastered. Judging from the distribution of test questions, many of the knowledge points examined come from the "Patent Examination Guidelines" of the State Intellectual Property Office's departmental regulations. It should be noted that many of the contents in the Guide are further refinements of the Patent Law and the Implementing Rules of the Patent Law. If the Guide can be understood in conjunction with the relevant provisions of the Patent Law and its Implementing Rules If so, the review effect can be doubled with half the effort. "Relevant legal knowledge" is characterized by "extensive" and involves many departmental laws, such as "General Principles of Civil Law", "Contract Law", "Administrative Reconsideration Law", "Civil Procedure Law", "Administrative Procedure Law", "Trademark Law", "Copyright Law", etc. Although there are many laws involved, many of them are direct examinations of legal provisions and the exam is not in-depth. In terms of the score distribution of various departmental laws, except for the Administrative Reconsideration Law, which has a score of 8, the other six laws basically have a score of more than 12 every year. As for the "Regulations on the Protection of New Plant Varieties", "Regulations on the Protection of Layout-Designs of Integrated Circuits", "Regulations on the Administration of Technology Import and Export", "Customs Protection Measures for Intellectual Property Rights" and other administrative regulations, as well as international conventions such as the Paris Convention and the TRIPs Agreement, they are divided into The values ??are relatively low. As for "Patent Agency Practice", it is a subjective question and the principle of "scoring points" is adopted. To a certain extent, writing is like an "eight-legged essay" with corresponding format requirements. Currently, you can find some previous practical scoring standards on the Internet. Candidates can do it by themselves first, and then compare it with the scoring standards to understand where they lost points. In addition, some answer templates summarized by high-scoring candidates or training class teachers can also be used as a reference. On the practical side, one thing that needs to be emphasized is not to think too much and to answer questions strictly based on the information given in the test questions. For those candidates with practical experience, they must pay attention to the fact that actual work is different from the exam, and some methods used in actual work cannot be used in exam questions. If the answerer regards himself as a newcomer who has just entered the industry and does not go beyond the boundaries, he will not easily lose points.
