How do I conduct a patent search? What are the ways to search for patents?

There are three ways to search for patents: paper search, software search and online search.

1. Paper retrieval: paper carrier is the main form of patent literature, but also the main object of retrieval, the information checked by paper retrieval is generally the least error-proof, the most evidentiary effect, but its efficiency in the patent retrieval process is low, time-consuming and laborious, easy to lose and damage, and due to the long printing and distribution cycle, the latest data retrieval is more difficult.

2. Software search: Software search usually includes microfiche, computer magnetic media and CD-ROM patent literature search. With the development and popularization of computer technology, CD-ROM databases have played an important role in patent search and access to full-text patents.

Although disc retrieval is fast, the limited sharing of disc retrieval limits its scope of use, and the speed of updating also has certain limitations.

3. Online search: fast, new content, but not legally effective, if you want to use it as evidence, you need the relevant departments to show the corresponding certificate, or through the legally recognized department after the retrieval and proof to have legal effect.

1. Open the degree network.

2. Enter the application number of the patent or click on the advanced search to retrieve the relevant information of the patent.

To put it simply, enter the patent search** (CNIPA, etc.), and enter the relevant information of the content to be searched (such as keywords, patent number, patentee, inventor, etc.) on the search page.

At present, there are three main ways of patent search in China, namely: paper search, software search and online search.

1.Paper search: Paper carrier is the main form of patent literature and the main object of search.

Key advantages: Paper-based search methods are the least error-prone and the most evidentiary. However, the process of patent search is inefficient, time-consuming, laborious, easy to lose, and the cycle of printing and distribution is long, and it is difficult to search for the latest information.

2.software retrieval; It refers to the search of patent documents including microfiche, computer magnetic media and optical discs.

The main advantages of microfiche and magnetic media: patent documents occupy small space, high storage density, long retention time, easy copying, etc. However, the limited sharing limits the scope of its use, and there are certain limitations to the speed of updates.

3.Online search has become the main method of patent search because of its incomparable data advantages, convenient and fast search, and not limited by time and space. Nowadays, online patent search has become the most important and fastest way to search.

1) Simple SearchSimple Search is located in the middle of the right side of the home page, providing 1 search entry and 1 search item option. Users can enter one search query (the search query can be a word, date, or number) in the search input box, select the drop-down list option of the search item to limit the search scope of the entered search query, and finally click it"Search"button. "Search for items"The drop-down list provides a total of 9 options, which are:

Application (patent) number, filing date, publication (notice) number, publication (notice) date, applicant (patent) holder, inventor (designer), name, abstract, main classification number. (2) Advanced Search: Click on the middle of the right side of the home page"Advanced Search"to enter the search page, and you can see that there is at the top of the page"Invention patents"、"Utility model patents"、"Design patents"There are three options, and by default, the search is in all patents, that is, all invention, utility model and design patents are searched. If selected"Invention patents"、"Utility model patents"or"Design patents", the search will only be conducted in the selected patent type database.

3)The IPC classification search is provided on the right side of the search page"IPC Classification Search"Click to enter the page to see the ** and class names of the 8 parts of the IPC on the left side of the page, and the 16 search fields on the right. Since IPC symbols only apply to invention and utility model patents, they are only displayed at the top of the page"Invention patents"with"Utility model patents"Two options. IPC classification search can realize the function of class name query and search of international patent classification symbols, and can be combined with classification codes and other fields on the basis of limited classification symbols, and all search fields are logical"with"Operation.

Click on the class name of any department, and the system will list the class names of the major categories, small classes, large groups, and groups under the department step by step, on the right"Classification number"The corresponding class name will appear in the entry, enter the search query in the other search portals, and click on the lower part of the page"Search", the results of the classification number and other field combination search will be obtained. If you click to the left of the class name"Search"word icon, the search results of all invention and utility model patents under the corresponding category will be obtained.
