How to carry out patent search? What are the detailed operation procedures of patent retrieval? Patent retrieval is a procedure before patent application. Not necessary, but necessary. An effective search report can make the applicant avoid that the right to be protected is not the same or similar to the earlier patent application, and ensure that the applied patent is valid. So how to carry out patent search? Next, we will introduce you to the detailed operation process of patent retrieval. How to carry out patent search? What are the detailed operation procedures of patent retrieval? Patent search 1 detailed operation flow. Why choose the right patent database? Because patents are regional, if the inventor's technology or technology extension goods want to exclude others from using, selling and manufacturing in a certain country, then it is necessary to apply for patent protection in that country. In addition, because patent information is a kind of technology disclosure to encourage inventions, all countries will apply for or disclose the approved invention patents in that country, so there is a free national database. However, patent applications and layouts often involve several countries. Therefore, it is not only a waste of time to search separately in different free patent databases, but also an error will occur because different databases use different languages and grammars (each country's databases use different grammars). Therefore, it is particularly important to choose a source file library with strong comprehensiveness and many data materials. 2. The contents contained in the general patent database are taken as an example. Among them, the patent database includes USPTO (oauth2.0 database in English), EU EPO, Japanese JPO, Korean KPO, China SIPO, Germany (de), Britain (GB), France (FR), Switzerland (CH), WIPO PCT, etc. All the above patent information queries can be conducted under a unified retrieval grammar and framework. In a word, these patent databases make it easier for users to search multinational patents at the same time by building a unified search interface. Detailed operation flow of patent retrieval III. An example is given to illustrate the retrieval syntax involved in the common patent database. For example, "(automobile or auto*) and (Siemens or Hyundai). Associated Press. And navigation. AB。 And @ ad =19860301=19931065438 "is (car or auto *). (Siemens or Hyundai) appears in the patentee, navigation appears in the abstract, and the application time is between1March 0, 9861and1June 5438+00, which can be used to further practice and expand other related advanced searches. Detailed operation flow of patent retrieval 4. The basic step in the process of patent retrieval (drafting keywords) is to draft keywords in the second stage, including five ways to draft keywords. They are 1. Basic keyword drafting (researcher), 2. Synonym extension (researcher), 3. Advanced Term Extension (Patent Engineer), 4. Company name merge (IT engineer) and 5. Time and technology classification restrictions (patent searchers). In the above five items, people in brackets indicate which role should play the main role, such as the formulation of basic keywords, which we think should be provided by researchers and the extension of superior terms should be provided by patent engineers. In addition, in the above five main tasks, in principle, patent retrieval personnel still carry out related work and operations (of course, researchers can also conduct retrieval on their own). Among them, the role of patent retrieval personnel is to cooperate with different experts to complete patent retrieval and analysis, and the related detailed operation skills will be further explained in future columns.
