How to identify infringement after patent application failure
1. The object of infringement should be the valid patent which has patent right in our country.
Patent right has regionality and timeliness
Regionality: generally, it should be authorized by the State Intellectual Property Office.
Timeliness: patent rights that are not invalid due to payment, invalidation, abandonment and other reasons within the specified protection period.
Note: if a patent right is declared invalid for some reasons, the patent right will be regarded as nonexistent from the beginning, so even if someone else has implemented it before, it does not constitute patent infringement.
2. There are illegal activities
That is to say, without the permission of the patentee, the doer has the act of exploiting the patent for profit.
Note: according to Article 69 of the patent law, any of the following circumstances shall not be regarded as infringement of the patent right:
（1） Using, promising to sell, selling or importing a patented product or a product directly obtained by a patented method after it has been sold by the patentee or a unit or individual licensed by him.
（2） Before the date of patent application, the same product has been manufactured, the same method has been used, or necessary preparations have been made for its manufacture or use, and it continues to manufacture or use only within the original scope.
（3） A foreign means of transport that temporarily passes through China's territorial land, waters or airspace uses the relevant patent in its devices and equipment for its own needs in accordance with the agreements signed between the country to which it belongs and China or the international treaties to which it is a party, or in accordance with the principle of reciprocity.
（4） The use of patents for scientific research and experiments.
（5） Those who manufacture, use or import patented drugs or patented medical devices for the purpose of providing information needed for administrative examination and approval, or those who manufacture or import patented drugs or patented medical devices for them.
3. The actor has subjective fault
Intention: the perpetrator carries out the act knowing that his act infringes the patent right of others
Negligence: the act of infringing the patent right of others due to negligence or overconfidence
Note: according to the second paragraph of Article 63 of the patent law, even if the perpetrator has no subjective fault, it also constitutes patent infringement, but does not bear the liability for compensation.
4. It should aim at production and operation
The purpose of production and operation should also be one of the elements of judging patent infringement.
Article 11 of the patent law stipulates that after an invention creation has been granted a patent right, except as otherwise provided in this law, no one shall exploit the patent, and exploitation shall not be for the purpose of production or business operation.
