How to search for patent families and what are the functions of patent families?

A patent family is a patent for an invention that has been filed in several different countries or regions. Such patents are called family patents or family patents. Generally, if there is a claim for priority, there will be information about the patent for which priority is claimed, and these two are patent families.

If priority is not claimed, since each country or region is relatively independent, in general, it will not indicate which patent families there are. In this case, it is necessary to search by patentee and keyword on the patent search ** in each country, because it is a family patent, the invention point keyword must be the same, so it is easy to search.

There were 241 patent family searches.

The method of analysis of the patent family is not entitled - it is considered withdrawn.

Through the patent family search, it can be found out in which countries the applicant has applied for a patent for the same subject matter of the invention? What is the status of approvals and legal status of these patents? In addition, by comparing patents in the same patent family, it is possible to obtain information about the latest technological advances that are not covered in the basic patents.

Normally, the more important the invention and creation, the more countries that apply for it, and the most active technology development, so for enterprises and scientific research institutions engaged in technological innovation, whether in the preparation stage of the topic or in the process of technology research and development, special attention should be paid to the role of patent family when retrieving or tracking patent information. When you come across a valuable patent document, you must not neglect to search for its patent family. (2) Patent families can help readers overcome language barriers.

When readers read patent literature, they often encounter the dilemma that they cannot read the patent documents they have or the search results at hand due to language barriers. The best way to solve this problem is to look up patent families. With a patent family search, you can access patent documents published in a language you are familiar with, thus solving the language barrier in a simple way.

3) Patent family can provide a reference for patent authorities to examine and approve patents. When examining and approving a patent, the examiner can use the patent family to share the search report or search results of other patent institutions when examining and approving the patent application for the same invention subject matter, and refer to the examination and approval results, the scope of protection of the claims and the modification of the application documents. (4) Patent family can solve the problem of insufficient collection of patent documents.
