If the signatures of QQ and WeChat say to quote other people's sentences or something, is this an infringement?

It is considered that quoting other people's sentences is strictly a kind of infringement, but it also needs to be divided into specific situations. Not every word is infringing, otherwise we can't write it. In fact, intellectual property is a very complicated thing, especially words and designs, which will be infringed if you are not careful. The following small series will talk about under what circumstances the quoted sentence is considered infringement or non-infringement.

First, the original author of the quoted sentence has clearly indicated the reprinting infringement.

Generally speaking, if the meaning of the sentence you quoted originally comes from the original author of an article, and the author clearly indicates it at the bottom of the article, please indicate the source of reprinting or prohibit reprinting; If it is still a blatant quotation and does not indicate the source, there will be infringement.

Second, it is also infringement not to quote more commonly used sentences.

Generally speaking, for those vernacular Chinese, if quoted, they are all used in common sentences. Bian Xiao believes that this does not constitute infringement. If this kind of infringement, then we have no way to create when writing, so we don't have to worry about the infringement caused by this situation.

Third, quoting ancient famous sentences is not infringement.

Strictly speaking, the famous sentences of the ancients are copyrighted, but since the ancients have passed away, quoting the words of the ancients does not constitute infringement. After reading this explanation, I think many people should be inspired. Why don't ancient famous sentences constitute infringement? In fact, in the final analysis, there is no infringer, so even infringement does not constitute a crime.
