1. query method: patent query can generally be queried in the database published by China National Intellectual Property Administration. You can also entrust a patent search center to make professional inquiries.
2. Analysis of patent types to be inquired: In China, there are three types of patents: invention, utility model and appearance patent. Only when the type of patent is determined can it be inquired.
3. If there is a patent number/application number, you can directly enter it in the column of patent number/application number.
Second, the query comparison
The purpose of patent search is to compare whether it is similar or not. You can operate through the patent search channel in China National Intellectual Property Administration. In order to query the comparison results more accurately and professionally, you can find a professional organization to handle it for you.
Third, the professional query operation process
Step 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 are to be used, sold and manufactured 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.
Step 2: Contents contained in the general patent database.
Take the patent analysis system BaiTengPatentSearch as an example, which includes USPTO (full text of open library and authorized library in English), 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.
Step 3: Search syntax involved in the general patent database.
Let's give an example to illustrate, such as "(Carorauto *), (Siemens SorHyundai). Associated Press. And navigation. AB。 And @ ad > =19860301<; =199310/0 "means that" (carorauto*) "appears in all fields," (SiemensorHyundai) "appears in the patentee," Navigation "appears in the abstract, and the application time is1March 0, 986.
Step 4: Basic steps in the process of patent inquiry (drafting keywords)
What needs to be done in the second stage is to draw up keywords, among which the method of "drawing up keywords" includes five items. 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 work items, in principle, patent inquirers are still responsible for the implementation and operation of related work (of course, researchers can also search by themselves), in which the role of patent inquirers 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.
Fourth, patent reading analysis
Patent inquiry is a means and process, and reading analysis after information retrieval is the purpose and importance.
Once the above inquiry procedure is completed, we can use the results obtained from patent search to read and analyze patents. Take the patent analysis system provided by BaiTengPatentSearch as an example. In principle, the most basic way to read patents is of course to start with the first one. For example, when 375 patents are retrieved this time, patent searchers can print these 375 patents one by one for the reference of relevant patent engineers or R&D personnel. However, patent information can be used in many different places, so we initially divide patent reading and analysis into three parts, namely, preliminary patent statistics (patent searchers), patent reading skills (researchers) and patent application scope deconstruction (patent engineers). In other words, patent searchers can use patent retrieval skills to find key patents or provide similar patent combinations for researchers to further interpret patents. Of course, it should be emphasized that the work of preliminary patent statistics is mainly to accelerate the interpretation of patent technology content and rights content, and it cannot replace the interpretation of final patents. In addition, the most important part of patent is not the explanation of technical content, but the deconstruction of patent claims with legal effect in patent specification. The so-called deconstruction of patent application scope means that patent engineers judge the scope protected by independent items or subsidiary items for each application scope (that is, the scope of rights granted to this patent by law), and finally construct the matrix relationship of patent application scope according to the application scope covered by each patent.

Verb (abbreviation of verb) What is patent duplicate checking?
The so-called patent duplication checking is to avoid patent duplication, and will query patents through some patent query tools and platforms; Then why check whether the patent has been copied by others? First of all, we need to tell you that patents are inventions, so inventions mainly depend on whether patents are novel or not. If someone else has already applied, it is meaningless to apply for a patent, and the patent office will not pass it.
Six, how to check the patent?
The patent can successfully pass the application mainly because the patent needs to have three characteristics: novelty, creativity and practicality. Therefore, duplicate checking is necessary, which is not only reflected in the success of patent application, but also in the efficiency and economy of patent research and development by the patentee. For example, some patentees or enterprises start to research and develop patents without considering whether the patent application is successful or not, which causes unnecessary economic losses due to the unsuccessful patent application.
There are many tools for patent duplicate checking, such as National Intellectual Property Network, soopat, Baiteng, etc., all of which have the function of patent duplicate checking, which is beneficial to individuals and enterprises to reduce unnecessary economic losses. This is also a reference method for many enterprises and individuals to protect intellectual property rights. If you want to apply for a patent successfully, or to improve the success rate of patent application, you need to search for a patent through a patent search tool and view a copy of the patent.
Nowadays, the patent duplicate checking tool has become an important tool for patent application inquiry. It is suggested that patentees make full use of these query tools to maximize the success rate of patents.
