First of all, you need to evaluate the value of the patent. The value of the patent is divided into two parts, one is the technical content, and the other is the writing quality. Only with high technical content can we find market value and partners; Only when the writing quality is high can the value of patent be reflected. If the quality of writing is poor, even if it is authorized, its stability is poor, and it is easy to fail and lose the patent right, that is, if you disclose the technology for nothing, others will not spend money on your technology, that is, no one will buy it.
Enterprises, especially large enterprises, will have a special person in charge of patents, which are generally purchased directly and rarely cooperated. Companies that buy patent applications usually make up the number, and the price is not high, unless your patent has great technical value.
