Taking invention as an example, briefly explain the mode of patent protection:
A company invented a new machine and applied for a patent in the patent office. In the application process, he must disclose the technical features of the invention, including details, without reservation.
Therefore, the patented invention is completely open in technical features, but no one else may use it without the permission of the patentee. Other patents (utility model, design) are the same.
If you want to use this patent, you can't use it at will because its technical features are open. Before using it, you must contact the right holder and get his authorization.
The specific ways to purchase the right to use a patent generally include the following.
1, buy out, buy out the patent completely. In the future, if others (including the original patentee) need to use the patent, they must obtain your authorization, which will cost a lot.
2. Buy the exclusive right to use the patent for a period of time, that is, only you can use the patent within the time range agreed between you and the patentee.
3. Exclusive right to use, that is, you get the right to use the patent through purchase, and others can also buy the right to use the patent from the patentee.
