You can't apply for patent protection for your creative scheme. Don't waste your time on this.
So how to protect yourself, I think there are the following points.
1. Form a more systematic and comprehensive copy and be protected.
2. Make a video material. You can make a speech or demonstration by yourself, and make various possible assumptions during it. This is also your creativity.
In China, fake Gui Li overthrew Li Kui jy everywhere. If you have confidence in your own creativity, you must fully safeguard your own interests. Don't repeat twists and turns.
I suggest you keep a hand when you apply for a job, and don't completely expose your bottom line.
The confidentiality agreement you signed in the company is redundant, which may lead your future company to take away your idea directly without giving you a penny, because he can say that this idea was made during your tenure, and according to the law, such intellectual property rights are controlled by the company, and without prior agreement, you lose more than you gain.
6. If you have evidence to prove that others have really copied your ideas on this subject (in fact, it is difficult to define this according to China's intellectual property protection law), you can pursue the right to sue according to People's Republic of China (PRC)'s Anti-Unfair Competition Law, but in reality, the lawsuit is often smelly and long, and even if it wins, it is difficult to get compensation. Not cost-effective.
This is the most important point for your reference.
1. Send your creative text or video materials to yourself in an envelope. Don't open the envelope, keep it intact. Then you can prove that the original author of this idea will be protected by law. You should design more variations, because plagiarists often don't copy the original.
2. notarization. If the company you work for is willing, you can sign a notarial certificate with him, which is legally binding and not difficult to operate. Or you can sign a contract with any company, not the company you will work for, as long as you prove that the idea is your own. If there was a dispute at that time, this notarization had complete legal evidence.
I hope the above answers are helpful to you.
