If the signatures of QQ and WeChat say that they quoted other people's sentences or something, is this an infringement? Does anyone know?

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 any sentence will be infringing, otherwise we can't write. In fact, intellectual property is a very complicated thing, especially for writing and design, and infringement will happen if you are not careful. The following small series will talk about under what circumstances the quoted sentence is considered infringement or non-infringement.

1. The original author of the quoted sentence has clearly indicated that the reprinting is infringing.

Generally speaking, if the sentence you quoted said that the meaning represented originally came from the original author of an article, and this author clearly indicated at the bottom of the article, please indicate the source of reprinting or prohibit reprinting; If you still cite it blatantly and don't indicate the source, there will be infringement.

second, it is not an infringement to quote in more commonly used sentences.

Generally speaking, for those vernacular Chinese, if you quote them, they are used in common sentences. Xiao Bian thinks 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 an infringement.

Strictly speaking, the famous sayings of the ancients are copyrighted, but since the ancients have passed away, quoting them does not constitute infringement. After reading this explanation, I think many people should be enlightened. 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.
