(2) Professional patent inquiry procedures
1, select the appropriate patent database.
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 comprehensive source file library with a lot of data.
2. Contents contained in the general patent database
Take Patents Search, a patent analysis system, as an example. The system includes USPTO (English full text of open database and authorized database), EU EPO, Japanese JPO, Korean KPO, China SIPO, Germany, Britain (GB), France (FR), Switzerland (English bibliography), WIPO PCT and other patent databases. 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.
3. Search syntax involved in the general patent database.
