Abstract: What are the steps for patent search? How to search for patents? Patent literature search methods can not only help you understand the cutting-edge of related technologies, but also broaden your horizons. Moreover, patent inquiries before applying for a patent are very necessary to avoid encountering some problems and troubles. So why do you need to check whether the patent is duplicated by others? Are there any patent tools or platforms that can search whether the patent is duplicated by others? Let me tell you how to search for patents. 1. Query steps
1. Query methods: Patent queries can be carried out in general queries in the database disclosed on the State Intellectual Property Office website; you can also entrust a patent search center to conduct professional queries.
2. Analyze the type of patent to be queried: In China, patent types are divided into three types: invention, utility model, and appearance patent. Only after determining the approximate type of patent to be queried can the query be carried out.
3. If there is a patent number/application number: You can enter it directly in the patent number/application number column.
2. Query and comparison
The purpose of searching patents is to compare whether they are similar. You can operate it through the patent search channel of the State Intellectual Property Office to make the query and comparison results more accurate and professional. , you can find a professional agency to handle it for you.
3. Professional query operation process
Step 1: Choose a suitable patent database
Why should you choose a suitable patent database? Because patents are territorial, if the inventor's technology or technology extension products want to "exclude others" from using, selling, and manufacturing in a certain country, then he or she needs to apply for patent protection in that country. In addition, since patent information is a kind of technology disclosure that encourages inventions, every country will disclose the invention patents that have been applied for or approved in that country, and therefore there is a free database for each country.
However, patent applications and layout often involve several countries. Therefore, searching separately in different free patent databases not only wastes time, but also causes errors due to the differences in the language and syntax used in different databases (the syntax used in databases in each country is different). Therefore, it is particularly important to choose a source file library that is comprehensive and has a lot of data.
The second step: the content contained in the general patent database
Using the patent analysis system Baiteng ( BaiTengPatentSearch) for example, the patent databases included are USPTO (full text of English data in public database and authorized database), EU EPO, Japanese JPO, Korean KPO, Chinese SIPO, Germany (DE), United Kingdom (GB), France ( FR) and Switzerland (CH) (English bibliographic data), and WIPOPCT, etc., and the above patent data queries can be carried out under a unified search syntax and structure. All in all, these patent databases allow users to simultaneously search patents from multiple countries by constructing a unified search interface, thus making patent search and analysis tasks simpler.
Step 3: Search syntax involved in general patent databases
We will illustrate with an example, such as "(carorauto*)and(SiemensorHyundai).ap.andnavigation.ab.and @adgt;=19860301lt;=19931010" means "(carorauto*)" appears in all fields, "(SiemensorHyundai)" appears in the patentee, "navigation" appears in the abstract, and the application time is between March 1986 For patents between 01 and October 10, 1993, other related advanced searches can be further practiced and expanded using this mode.
Step 4: Basic steps in the patent search process (preparing keywords)
The work required in the second stage is to develop keywords, among which "preparing keywords" The method includes five items.
They are 1. Basic keyword development (researcher), 2. Synonym expansion (researcher), 3. Hyperlingual term expansion (patent engineer), 4. Company name merger (IT engineer), and 5. Time and technology classification Restriction (patent search personnel). Among the above five items, the person in brackets indicates which role should play the main role. For example, we believe that the basic keyword formulation should be provided by researchers, and the expansion of higher-level terms should be provided by patent engineers, etc. In addition, in the above five main work items, in principle, patent search personnel are still responsible for the execution and operation of relevant work (of course, researchers can also conduct searches by themselves). Among them, the role that patent search personnel need to play is to coordinate Different experts can complete the work of patent search and analysis. We will further explain the relevant detailed operation skills in future columns.
4. Patent reading analysis
Patent search is a means and process, and the reading analysis after retrieving the information is the purpose and importance.
Once the above search process is completed, we can use the results obtained from the patent search to carry out patent reading and analysis. Take the patent analysis system provided in the BaiTengPatentSearch system as an example. In principle, the most basic way to read patents is of course to start with the first one. For example, when the number of patents retrieved this time is 375, the patent searcher can print out the 375 patents one by one and provide relevant patent engineers or It is a reference for 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 Engineer) etc. That is to say, patent search personnel use patent search techniques to find key patents or provide similar patent combinations to researchers for further patent interpretation. Of course, it needs to be emphasized that the preliminary patent statistics work is mainly to speed up the technical content and rights content of patents. The interpretation cannot replace the interpretation of the final patent. In addition, the most important part of a patent is not the interpretation of the technical content, but the deconstruction of the legally binding patent application scope (claim) in the patent specification. The so-called deconstruction of the patent application scope is to use the patent engineer to determine the scope of protection of each application scope as an independent item or ancillary item (that is, the scope of rights granted by the law to this patent), and finally based on the scope of protection covered by each patent. The patent application scope matrix relationship is constructed by the application scope. How to register a trademark gt; gt;
5. What is a patent duplication check?
The so-called patent duplication check is a patent. In order to avoid duplication of patents, the patents are passed through some patent query tools. , platform for patent query; then why do you need to query the patent? Is it duplicated by others? First of all, I need to introduce to you that a patent is an invention and creation. Therefore, the key to an invention and creation is whether the patent is new. If someone else has already applied for it, there is no point in applying for a patent and the patent office will not approve it.
6. How to check for duplicate patents
The successful application of a patent is mainly reflected in the fact that the patent needs to have these three characteristics: novelty, creativity and practicality. Therefore, plagiarism checking is very necessary, which is not only reflected in the success of the patent application, but also in the efficiency and economy of the patent R&D by the patentee; for example, some patentees or companies start the patent application without considering whether the patent application will be fruitful. Research and development of patents will cause unnecessary economic losses due to unsuccessful patent applications.
There are many tools for patent plagiarism checking, such as the National Intellectual Property Network, soopat, and Baiteng.com, etc., which all have functions for patent plagiarism checking, which is helpful for individuals and enterprises to reduce unnecessary mistakes. Economic losses, this is also a reference method for many companies and individuals to protect intellectual property rights. If you want your patent application to be successful, or if you want to improve the success rate of your patent application, you need to conduct a patent search on the patent and use a patent search tool to check for patent duplication.
Nowadays, patent plagiarism checking tools have become an important tool for querying patent applications. It is recommended that patentees try to make use of these query tools to maximize the success rate of patents.
