If you have time, I suggest you study the laws related to intellectual property rights and the content of enterprise intellectual property strategy.
Now all kinds of economic globalization is an inevitable trend. As enterprises in China, they must learn to arm themselves with legal weapons, otherwise they will be bullied by enterprises in other countries.
Our country has spent so much money to encourage patent applications in recent years, just to let China enterprises know and understand patents and make money from them. But in fact, most enterprises only stay at the level of "applying for patents in order to obtain government subsidies". If enterprises can fully realize the importance of intellectual property rights and seriously apply for patents, they should be able to avoid many similar situations and avoid a lot of duplication of work.
Learn to be a "man standing on the shoulders of giants".
