The common types of patent retrieval include patentability retrieval, infringement retrieval, technical subject retrieval, patent legal status retrieval and patent family retrieval. The following are introduced separately.
Patent retrieval
Patent retrieval is a retrieval to judge whether an invention is novel and creative. Find out the most relevant comparative literature from the existing technical literature, and evaluate the invention and creation according to the standards of novelty and creativity, and then we can draw the conclusion whether it is patentable or not.
Patentability retrieval is often used for technical evaluation before patent application or technology trade, and for predicting whether R&D has the prospect of obtaining intellectual property protection before project establishment.
Infringement retrieval
Infringement retrieval includes preventive retrieval and passive retrieval.
Anti-infringement retrieval refers to the active patent retrieval of a new technology and new product in order to avoid patent disputes, with the aim of finding out the patents that may be infringed; Passive infringement retrieval refers to patent retrieval when others accuse it of infringement, and its purpose is to find out the basis for bringing an invalid lawsuit against the infringed patent.
Technical subject retrieval
Patent technology theme generally refers to: more than one set of technical solutions with the same technical attributes. The same technical attribute can refer to the same specific technical field or the same specific technical scope within the same specific technical field. Each technical topic mentioned here can contain multiple technical solutions.
Before the scientific and technological innovation of enterprises, it is necessary to search the technical topics of the topics to be developed, and all relevant technical documents and patent materials of the technical topics involved.
Patent legal status retrieval
Legal status refers to the right type, right maintenance, right scope and right attribution of a patent application or authorized patent in a certain country at a certain point in time, which will directly affect the existence and scope of patent right.
The retrieval of patent legal status refers to the retrieval of the current legal status of a patent or patent application. Its purpose is to know whether the patent application is authorized, whether the authorized patent is valid, whether the patentee has changed, and how other information related to the legal status of the patent is.
Patent family retrieval
Family patent retrieval refers to the retrieval and publication of other patents or patent applications with the same priority as the retrieved patents or patent applications. The purpose of this retrieval is to find out the family patent documents of patents or patent applications. Ordinary similar patent retrieval refers to simple similar patent retrieval.
Enterprises can choose appropriate patent retrieval methods according to their own needs and actual conditions.
