From the patent literature, why are there no patents of the same family?

Some netizens explained the basis of the same family patent, that is, they advocate the same priority and form the so-called "family" concept between patents in various countries with priority as a link. The advantage of priority is that when applying in different countries, the application date will not be delayed because of the problems of technology and language translation in various countries, which will cause novelty and creativity problems in the patent examination process.

However, in the actual operation process, sometimes enterprises do not want competitors to find the existence of the same patent. For example, they don't want their competitors to find out that this patent has been applied in the United States. At this time, enterprises will not claim priority when applying for American patents. In this way, competitors need to spend a lot of time to find out which patents they have applied for in the United States, and even gradually read and compare them when there are many patents. To a certain extent, it will cause trouble to competitors, even if competitors are not careful, they may fall into the scope of patent protection. However, it is suggested that the gap between the application date and the risks in the audit process should be reduced as much as possible when you are familiar with the application language and process.
