Patent Information Retrieval

 

Legal Status Retrieval

Legal status retrieval can be divided into patent validity retrieval and patent regional retrieval.

_Patent validity search: refers to the search of the current legal status of a patent or patent application, the purpose of which is to know whether the patent application is authorized and whether the authorized patent is valid. For example, whether a drug patent is still valid.

_Patent regional search: refers to the search of which countries and regions have applied for patents for an invention and creation. Its purpose is to determine the geographical scope of the patent application.

Other patent legal status information that can be retrieved include: cataloguing items of patent or patent application, change information, patent application, information in the process of examination or review, information of legal activities such as patent transfer, licensing and objection after authorization, etc.

 

Novelty search

Novelty retrieval can provide scientific basis for the evaluation of scientific research projects, completed scientific research achievements, inventions and patent applications, provide reliable and abundant information for scientific and technological personnel to carry out research and development, and provide objective basis for the appraisal, evaluation, acceptance, transformation and award of scientific and technological achievements.

For unregistered or completed scientific research projects, the function of novelty retrieval is to expand or validate research ideas, research methods and research means.

For inventions that want to apply for patents, HangSome searches for the content of patent rights, so as to provide a basis for patent writing evasion, and can effectively improve the success rate of patent applications.

Novelty search before scientific research and new product development can effectively collect patent information. According to the investigation and research, making full use of patent information can save about 60% of R&D time, and making R&D planning according to the results of novelty search can save nearly 40% of R&D expenditure.

 

Patent Search

An invention must be novel, creative, and practical before it can be granted a patent right. Among them, novelty, creativity and practicality are commonly referred to as "patentability".

Patent retrieval is to search the patent or patent application that has been retrieved, and to retrieve the existing patent documents at home and abroad, from which we can obtain the comparative documents to evaluate the patentability of the object.

A patent application can be searched for different purposes in the whole life cycle of the patent from the writing of the application, the examination and approval of the patent office to the authorization.

Search before Patent Application

Before patent application, patent documents and professional journals are searched for the two patented subjects in order to clearly understand the patentability of the patented subjects, so as to make correct decisions on whether to apply for a patent and how to obtain the most appropriate protection scope for the layout of claims, so as to maximize the interests of the applicants themselves. The patent agent will communicate with the applicant and give appropriate application suggestions according to the retrieval situation.

_Retrieval in the Process of Examination and Approval

The review opinions of the reviewers are retrieved in order to provide more convincing reasons or to modify the application documents more pertinently. Patent searches in this process usually provide factual basis for replying to reviewing opinions, such as creative evidence for inventions that overcome technical bias, sufficient evidence for the disclosure of instructions, and evidence for the correct interpretation of a technical term, etc.

_Retrieval after Patent Authorization

The search after patent authorization is usually carried out by the public who think that the granted patent may not meet the patentability conditions. For example, the patent invalidation procedure provides the patent invalidation search of comparative literature. The main purpose of invalid retrieval is to retrieve existing technical documents that can be authorized for patent novelty or creativity.

 

Infringement search

Infringement search is to make a conclusion whether the patent right is infringed or not, generally refers to the search to determine whether the products produced or the processes used are included in the scope of protection of the authorized patent right. According to the relationship between the infringer, the infringed party and the searcher, the infringement search includes: preventing infringement search and accused infringement search.

_Preventing Infringement Retrieval

In order to avoid infringement disputes, patent literature retrieval for a new technology or product is carried out actively. Its purpose is to find out patents that may infringe the scope of patent protection. For example, when exporting new products to foreign countries, enterprises should search patent documents to determine whether the patent rights of the country in which they export will be infringed. According to the law of the exporting country or region, HangSome consults the term of protection of valid patents. The Anti-infringement search of new products can effectively avoid the infringement risk for enterprises.

 

Accused Tort Retrieval

The retrieval of alleged infringement refers to the patent search conducted in self-defense when the accused infringement is accused. Its purpose is to find out the evidence of invalidity or non-infringement of the alleged infringement patent. For example, a product manufactured by an enterprise is accused of infringing the invention patent of another enterprise of the same type. By searching the existing technology, the enterprise retrieves an American patent which is identical to the technical scheme of the patent claim and declares the patent invalid on the basis of a request disclosed before the date of the patent application.

 

Technical Trade Retrieval

In the process of technology trade, especially in introducing foreign advanced technology, technology trade retrieval is very important. HangSome learns about the development of technology, whether it has applied for a patent and whether the patent right is valid by searching patent documents so as to grasp the actual situation. For example, before introducing foreign technology, whether the technology contains patented technology is retrieved, so as to avoid being bound by patented technology in the later stage of technology implementation.

 

Patent Strategy Retrieval

Patent documents accumulate detailed information on inventions and creations in various fields of technology, including technical content, applicant status, application country and legal status. If we can search the patent documents in a technical field systematically and collect useful information, we can judge the current situation and trend of the development of a certain technology and understand the research situation of competitors or peers through systematic statistical analysis, so that enterprises can reasonably choose the research and development objectives and seek the greatest development and results with the best scheme and the least investment.

Through searching and analyzing patent documents in related fields, this paper reveals the technological development points, and then formulates its own technological research and development direction and patent layout strategy retrieval, that is, patent strategy retrieval.

In addition, HangSome also provides tracking and retrieval of patent titles at home and abroad. It is a long-term patent monitoring search business based on the R&D needs of enterprises, formulating search topics consistent with R&D direction, and can timely obtain the latest patent literature on this topic.

 

Customized Retrieval Service

HangSome also provides customized retrieval services for customers, and formulates retrieval services according to their specific needs.
