When buying a patent, you must first confirm what patent you are buying and whether it is consistent with the contract. The patent name may be the same, but the patent number is unique, so you must identify the patent number and indicate it in the contract.
2. Pay attention to the legal status of patent right.
There can be many patentees, so when you buy a patent, you should pay attention to how many patentees there are and whether the patent seller has the right to sell the patent to avoid the contract being invalid.
3. Pay attention to the authorized use of patents.
Before buying a patent, you must first know whether the patent is licensed or even exclusive. These should not only be understood, but also clearly stated in the contract to avoid the situation that the patent cannot be used after purchasing the exclusive license.
4. Pay attention to whether the patent is in the correct state.
It is necessary to pay the annual fee in time when applying for a patent, so before signing the patent transfer, it is necessary to know whether the patent has failed to pay the annual fee in time or was declared invalid.
5. Pay attention to the validity of the patent.
Each patent has a certain period of validity, and the limitation period of different types of patents is also different. For example, the protection period of invention patents is 20 years, while the protection period of utility models and designs is only 10 years. Therefore, when buying a patent, you need to pay attention to how long the validity period is. The longer the validity period, the greater the patent value.
6. Find a formal intermediary.
When purchasing a patent, it is generally handled through the help of relevant intermediary companies. At present, the patent trading market is not standardized, and it is easy to be fooled into the trap of black intermediaries, which not only wastes people and money, but also delays their own affairs. Therefore, it is particularly important to be responsible for the agency reliably, so as to ensure the patent purchase.
