Regarding the situation you raised, you can communicate with the company's intellectual property department, or directly contact the person in charge of the company's technology to negotiate on patent licensing or patent transfer matters.
But at least there are several problems. First, the other party ignores it; second, the other party knows your patented technology and once again improves your patent to avoid the scope of your patent protection.
If your patents are not well laid out and you negotiate with a certain company on just one or a few patents, the most likely result is that they will be ignored and the patents will be avoided.
