METHOD OF FINDING PATENT FOR TECHNOLOGY TRANSFER AMONG RELATED PATENTS [0002]

The present invention relates to a patent search method to be transferred to a related patent, and more specifically, to a company that desires to search for a patent to be transferred to a related patent, in particular, , The patent related patents that are ahead of the duration of the related patents or have already paid the annual fee have been provided as technology transfer patent candidates to obtain the relevant patents more quickly and at a lower cost To a patent search method subject to transfer of technology in related patents.

It is essential that SMEs receive various certifications for bidding or trading of government, municipalities or public institutions, or as qualification requirements for delivery to private companies. At this time, what is absolutely necessary is intellectual property rights such as patents in the field of business.

In such a situation, it is very time-consuming for SMEs to find patent ideas in the business field, and to obtain patent registration by privatizing ideas that have been discovered through consultation with patent attorneys. It is not realistic to acquire rights through application of ideas for SMEs that require qualification to make transactions, or for the delivery to private companies.

In this case, it was common for SMEs to find related patents as technology patents through acquaintances. Even if the related patents are sought, the position of SMEs that need urgent patents will provide a bad environment for negotiating conditions such as technology transfer amount.

Korean Patent No. 1327514 (Nov. 31, 2013), title of the invention: patent network analysis system using semantic patent similarity and patent network analysis method using the same

FIG.

Referring to the drawings, a method for retrieving a technology transfer target patent in a related patent according to the present invention includes a first step (S100) of preparing a patent database; A second step (S200) of receiving a specific patent; A third step (S300) of searching for a related patent related to the specific patent using the related patent model; And a fourth step (S400) of determining whether the expiration date of the survival period exists within a specific period from the current date, and providing the patent as a technology transfer patent candidate among the related patents.

Here, the patent database is collectively referred to as a patent database, and includes not only registered patent, open patent, patent application but also registered patent application, public utility model, utility model registration application, registered design, public design, And a database containing at least one of these.

The patent, etc. stored in the patent database includes the country code, the application number, the filing date, the name of the invention, the summary, the claim of claim, the number of claims, the publication number, the publication date, the announcement number, Main classification, CPC all classification, IPC all classification, US patent classification, US All patent classification, European main patent classification, European all patent classification, F-term, FI (file index), applicant, applicant nationality, The invention includes at least one of inventor, inventor nationality, priority country, priority number, priority claim date, family patent information, backward citation information, and forward citation information.

Further, the patent database provides an information service to a user computer through a wired / wireless network (not shown). The patent database may be stored in a distributed or centralized manner in each patent office or a system of a raw data provider or a system of an enterprise information provider providing patent raw data, but it is not limited thereto and can be variously implemented. It may be a patent database which is constructed by using the data received through the query to the relevant patent office search engine.

Also, the specific patent received in the second step (S200) is at least one of a registered patent, a registered utility model, a patent application, a utility model registration application, a registered design, or a design registration application related to a business field of a small- , And information for specifying a specific patent including at least one of a patent number, a public number, and a registration number of a specific patent.

The related patent model for searching related patents includes a backward citation score that indicates the number of common backward citations between any of the patents and patent databases, A forward citation score indicative of the number of common forward citations between any patent and any patent and a time score indicating the temporal proximity between a particular patent and any patent, A CPC main classification score indicating whether the CPC main classification between arbitrary patents is common and an IPC main classification score indicating whether the IPC main classification between a specific patent and any patent are common, , A UPC message indicating whether the UPC main classifications between specific patents and arbitrary patents are common A CPC classification score indicating the number of common CPC classifications between a specific patent and any patent and an IPC classification score indicating the number of common IPC classifications between a specific patent and any patent, A classification score (IPC classification score), a UPC classification score indicating the number of common UPC classifications between the specific patent and the arbitrary patent, and text mining for each of the specific patent and the arbitrary patent The related patent can be searched based on at least one of the keyword scores extracted by comparing the extracted core skill keywords and the keyword score indicating the number of common core skill keywords between the specific patent and the arbitrary patent.

Here, the backward site refers to a case where a specific patent is described as a prior art, or the applicant himself or herself submits through an information disclosure statement at the examination stage of a specific patent, is quoted at a stage of examination of a family patent, Means patent documents or non-patent documents cited by the examiner at the examination stage of the patent.

In addition, the forward site is a patent application in which a specific patent is cited in a later patent application, that is, when a later patent application is filed, the applicant may submit the patent as described in the prior art, or the applicant himself / It will be a direct site or, if quoted by an examiner at the screening stage, be a forward site.

In addition, patent applications of the same field that exist within the nearest time in the trend of patent application or technological development are likely to include similar technical content, so this assumes that these factors are one factor. Or, it is a significant factor in extracting patents that are close in time that are not extracted by the forward site or backward site because of the patent disclosure system, for example 1.6 to 2 years.

In addition, the more similar the technical classification such as CPC, UPC (USPC), IPC, etc., and the more common technical classification, the more likely it is the related patent. The CPC, UPC, IPC, and IPC, respectively, were obtained and the values were obtained by using the number of common classifications. However, the number of common technical categories for all the various technical categories such as CPC, UPC, IPC, FI, F- It is also possible to calculate the related patent scores using

The keyword score is a value indicating the number of common core technology keywords between a specific patent and any patent by comparing the core technology keywords extracted through text mining for each specific patent and any patent. It is also possible to determine in advance the number of key technology keywords extracted through text mining in advance.

Further, in the third step, the relevant patent score indicating the scale of the related patent can be calculated by the following expression (1), and the relevant patent can be searched.

[Equation 1]

Further, in the third step, the relevant patent score indicating the scale of the related patent can be calculated by the following expression (2), and the related patent can be searched.

&Quot; (2) "

Here, the value chain score is a score given when the applicant or the holder of the specific patent exists on the value chain, that is, in the case of a business in a forward industry or a rear industry.

The weight, or weight, can be obtained by extracting patents that are actually searched and examined in the output related patents and can be adjusted through continuous learning, machine learning, and deep running.

Of the related patents thus extracted, in the fourth stage, related patents that are due to expire within six months from the current date, or which have not yet been paid in an annual fee within six months from the present date, are transferred as technology transfer candidates The method comprising the steps of:

Of course, it is possible that the duration will expire within three months from the current date, but it is also possible to extract a patent that is due to expire within one year.

However, pursuant to Article 81 of the Patent Act, it is possible to pay the annual fee within six months (additional payment period) after the end of the payment period, so that the related patent that has already been paid within six months from the present date Most preferred.

In this way, related patents with high relevance to the business field of SMEs are provided with the related patents that are ahead of the expiration date or have already paid the annual fee, as technology transfer patent candidates, Thereby providing a favorable environment in terms of conditions, making it possible to acquire related patents more quickly and at a lower cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
