What's the difference between technology transfer and patent buyout?

Technology transfer: it can be transferred to a, b, c, d and many other companies, and everyone can use it. As long as someone pays, there is no upper limit to the income in theory, and at the same time, the risk is great and the technology is backward. After being innovated or copied, no one buys it and receives no money.

Patent buyout: if you sell it, it will be gone, which has nothing to do with you. Take a sum of money and leave at one time. There is no risk and a fixed income.

Patent transfer in China usually takes the following three forms:

1, overall patent transfer, implementation of exclusive license, so-called patent ownership transfer, 10 years of independent property rights. If the patentee (inventor) transfers the whole patent to an enterprise, the inventor (patentee) only has the right of invention after both parties sign the transfer contract.

2. The exclusive license for patent exploitation means that the enterprise buys out the patent, and only the patentee and domestic enterprises can use the technology, and the patent cannot be transferred to a third party again.

3. The general license for patent exploitation means that the patentee authorizes an enterprise or individual to produce the patent, or may authorize multiple enterprises or individuals to produce the patent.
