Description

Technology Field

[0001] The present invention relates to literature search technology, and more specifically, to a patent search application device and a patent search method using the same. Background Technology

[0002] The purpose of patent rights is to protect newly developed technologies as exclusive rights. Therefore, to be protected by a patent, requirements such as novelty and inventive step must be met, and a prior art search is required to determine whether these requirements are satisfied. Furthermore, conducting a prior art search in the relevant technical field can prevent unnecessary duplicate investments. Companies may become entangled in patent disputes if they proceed with product development while overlooking the existence of prior art. Therefore, a prior art search is a critical task for both patent applicants and companies.

[0003] Today, the pace of technological development is accelerating, and most information can be shared globally via the Internet. Furthermore, since technologies from both domestic and foreign sources can be cited when filing a patent application, the amount of data required for a prior art search is vast. Consequently, even when conducting a prior art search using appropriate keyword combinations, there are anywhere from dozens to thousands of prior documents in related technical fields, and because the amount of documents a human can read is limited, there are limitations to conducting an optimal prior art search.

[0004] With the recent increase in the volume of data, various search technologies for prior art patent searches are being developed and utilized. Efforts for efficient data retrieval are being made, including methods that classify data components based on their direct or indirect relationship using data mining techniques, methods that extract keywords from patented technologies to facilitate analysis and generate specific variables using the extracted words, and the development of patent search devices that generate search queries using patent classification databases.

[0005] However, most efforts to improve data processing focus solely on information processing algorithms for data such as keywords; while this offers the advantage of efficiently processing vast amounts of data, it has limitations in reducing the absolute volume of data. Furthermore, methods for extracting keywords or patent searches utilizing the aforementioned patent classification and patent classification databases merely locate patent documents containing many keywords common to the invention or technology being searched, and they have limitations in that they fail to obtain advanced analytical results, such as information on changes in ownership of the technology or companies considering its commercialization.

[0006] As technological competition intensifies, the technological trends of interest to companies and research institutions are changing rapidly. However, current commercial patent search devices simply provide search capabilities based on information such as filing and registration dates, sorted in descending or ascending order, or set to a specific period. Searches based on these methods fail to provide particularly useful information, such as the behavior of competitors; furthermore, if the specific period is set incorrectly, it may deviate from the technological trends and actually hinder the selection of highly relevant patent documents.

[0007] Furthermore, in the case of research institutions such as universities or national research institutes, most patented technologies are obtained through research and development in basic science, elucidation of principles, or source technologies, rather than being technologies that can be directly applied to industrial fields or are mass-produced technologies preferred by companies. Since patented technologies corresponding to the aforementioned basic science or source technologies often do not achieve commercialization in the near future, if these uncommercialized patents accumulate over a long period, management costs such as patent maintenance fees can place a significant burden on the finances of the research institutions. Therefore, it is necessary to organize the accumulated patents held by these institutions, and to do so, a method capable of reliably assessing the commercialization potential of the aforementioned patented technologies is required. The problem to be solved

[0008] The problem that the present invention aims to solve is to provide a patent document search method that differs from the development of existing keyword extraction-search methods and searched data processing algorithms, thereby limiting the absolute amount of data that must be reviewed to select optimal patent documents; to generate advanced analytical information regarding the technology of interest and other competitors, which is useful for creating a business portfolio and establishing a commercialization plan for the technology of interest; and to provide a patent search application device capable of reliably determining the commercialization potential of accumulated patented technologies held by research institutions.

In another embodiment, if the target paper material is published by co-authors, the information received as the first paper information may be searched by being limited to the case where the co-author is of a certain rank, and the certain rank may be received from the client terminal device (200) or set as a base for being a co-author of the second rank or higher. In addition, the information on the aforementioned affiliated and sponsoring institutions may include the names, unique numbers, addresses, and names of the representatives of the said institutions. The names of the said academic societies and journals may be searched using their full names or English abbreviations, and may or may not be distinguished by uppercase and lowercase letters.

[0042] Referring to FIG. 3, the first paper information can be entered into an input field of the first paper information (PI1) displayed on the output of the client terminal device (200), and a search field of the entered first paper information can be designated for accurate search results. A single or multiple search fields can be selected, and for each of the selected search fields, a search can be performed using the entered first paper information as a keyword. Additionally, a single or multiple keywords can be entered into the input field, and the keywords can be simply listed or entered as a search expression using a search operator, and multiple input fields can be provided, and a search field and a search operator for each of the multiple input fields can be selected.

[0043] Referring again to FIG. 2, the patent search unit (130) can search for target patent documents related to the first paper information (PI1). In one embodiment, the target patent documents may include published, withdrawn, expired, abandoned, invalidated, rejected patent applications, registered patents, or a combination thereof. Additionally, the target patent documents may be searched on an online website or in a database stored in a local storage device, or may be searched by accessing an external server connected to the patent search application device (100) via a network.

[0044] In the patent search unit (130), when comparing the author of the first paper information (PI1) with the applicant or inventor of the target patent document, it may be determined whether they are the same person. In one embodiment, the name of the author, the applicant, or the inventor may be entered in Korean or English, and the name entered in Korean may be compared with the Korean name, and the name entered in English may be compared with the English name to determine whether they are the same person. In another embodiment, English may be used as the basis, the Korean name may be converted into the English name, and the full name or initial of the English name may be classified and stored as information referring to the same person. For example, if the Korean name is Hong Gil-dong and the English name is Hong Gildong, information such as Hong Gildong, Hong Gil-dong, G Dong Hong, and GD Hong may be classified as information referring to the same person.

[0045] Referring again to FIG. 2, the patent search application device (100) further includes a paper information generation unit (120) that generates second paper information (PI2) based on information extracted from the target paper data, and the target patent document searched by the patent search unit (130) may be related to at least one of the first paper information and the second paper information.

To avoid redundant descriptions, the description of the keywords of the individual patent information (PTI) will be described later in FIG. 5b.

[0054] The patent search-output unit (131) can search for a patent document in which at least one of the individual patent information (PTI) matches the first paper information (PI1) or the second paper information (PI2), and assign and output it as the target patent document. In one embodiment, only the first paper information (PI1) received from the client terminal device (200) may be used as a comparison target to determine whether it matches the individual patent information (PTI), and in another embodiment, when the second paper information (PI2) is extracted by the paper information generation unit (120), the first paper information (PI1) or the second paper information (PI2) may determine whether it matches the individual patent information (PTI), and if it matches, the target patent document may be detected. The individual patent information (PTI) of the target patent document may include a single or multiple identical pieces of information among the first paper information (PI1) and the second paper information (PI2). In one embodiment, weights may be assigned to the target patent documents according to the number of identical information, and the weights may be matched to each of the target patent documents. By assigning the weights, if there are multiple target patent documents, the target patent document with the larger weight may be determined to have a higher similarity or match, thereby being displayed at the top of the search result list or assigned a quantified index such as a score or level. Optionally, weights may be assigned in order of the number of specific information received from the client terminal device (200) among the identical information, and the target patent documents may be rearranged according to the magnitude of the weights.

[0055] Referring to FIG. 5b, the patent search unit (130b) may include a patent information extraction unit (132), a second patent database unit (PTDB2), and a patent search-output unit (131). The description of the patent search-output unit (131) may refer to the disclosures described in FIG. 5a, unless contradictory. The patent information extraction unit (132) may extract individual patent information (PTI) from a plurality of patent documents (PTS). Each patent document may be matched, and each patent document is identified by patent document identification information such as an application number, publication number, international application number, international publication number, registration number, or a combination thereof, and the extracted individual patent information (PTI) may be matched with said patent document identification information. The description of the plurality of patent documents (PTS) may refer to the disclosures regarding the target patent documents of the patent search unit (130) described in FIG. 2 and the disclosures described in FIG. 5a, unless contradictory.

[0056] Individual patent information (PTI) may include the purpose of the invention, background technology, claims, effects of the invention, specific details for implementing the invention, filing date, keywords related to at least one of the applicant or inventor, synonyms, similar words, alternative words, and equivalents of said keywords. Individual patent information (PTI) may be extracted in advance as described above with reference to FIG. 5a and stored in the first patent database unit (PTDB1). In another embodiment, individual patent information (PTI) may be extracted by the patent information extraction unit (132) and stored in the second patent database unit (PTDB2). In one embodiment, said keywords may be extracted by being limited to those included at least a predetermined number of times in the purpose of the invention, background technology, claims, effects of the invention, and specific details for implementing the invention of the patent document (132), and said predetermined number may be set for each field of patent information (133) or for all said patent documents. In another embodiment, multiple keywords are extracted from each patent document, and among the extracted multiple keywords, a priority is assigned based on the number of times they are included in each patent document, and among the keywords arranged according to the priority, keywords of a certain rank or higher may be included in individual patent information (PTI). Additionally, in the patent search unit (130b) according to another embodiment, the certain rank may be automatically set by the patent search application device (100) or manually set by information received by the client terminal device (200). As long as the description of the identification information of the applicant and inventor is not contradictory, the disclosure regarding the name of the author, applicant, or inventor in the first paper information (PI1) described above in FIG. 2 may be referenced.

[0057] Referring again to FIG. 3, the patent search unit (130) may include a first restricted search unit (SC1) or a second restricted search unit (SC2). In one embodiment, the patent search application device (100) may receive information regarding the application of a restricted search by the first restricted search unit (SC1) or the second restricted search unit (SC2), and a time limit condition (e.g., from January 1, 2019 to April 30, 2019) on the search screen of the client terminal device (200). Additionally, the patent search application device (100) may search for the target patent document with a search condition that the target paper material was published within the priority claim period of the target patent document and / or within the disclosure period of the target patent document.

[0058] The first restricted search unit (SC1) can search for the target patent documents by restricting the search to those filed within the grace period for claiming exceptions to public disclosure of the target paper data. According to Article 30 of the Korean Patent Act, if a patent is disclosed by a person entitled to obtain a patent or against the will of said person, it is deemed not to be publicly disclosed when determining novelty and inventive step if a patent application is filed within 12 months from the date of disclosure. Accordingly, when the target patent documents are searched by restricting the search to those filed within the grace period for claiming exceptions to public disclosure from the publication date of said paper data, patent documents with high relevance and similarity to said paper data can be searched restrictively. In another embodiment, the grace period for claiming exceptions to public disclosure varies by country, such as 1 year for Korea and the United States, and 6 months for Japan, China, and Europe; accordingly, the patent search application device (100) can set the grace period for claiming exceptions to public disclosure differently for each country.

[0059] The second restricted search unit (SC2) can search for target patent documents by restricting the search to those filed within an earlier or later period limit based on the submission or publication date of the target paper material. In one embodiment, the patent search application device (100) can receive search conditions regarding the earliest and latest filing dates of the target patent documents from the client terminal device (200), and can receive search conditions regarding the submission or publication date of the target paper material, the earlier period limit, and the later period limit. Additionally, as an example, the patent search application device (100) can recommend the best period limit conditions and display them on the client terminal device (200).

[0060] FIG. 6a is a configuration diagram of a patent search application device (300a) according to another embodiment, and FIG. 6b is a configuration diagram of a patent search application device (300b) according to yet another embodiment.

In one embodiment, the interface unit (310) may receive first paper information regarding target paper data from a client terminal device, the citation relationship paper search unit (350) may search for paper data that is in a citation or citation relationship with the target paper data to obtain target paper data and target paper information regarding the target paper data, and the patent search unit (330) may search for first target patent documents related to the target paper information. The description of the interface unit (110) and the first paper information (PI1) may refer to the disclosures described in FIG. 2, provided there is no contradiction, and the description of the patent search unit (330) may refer to the disclosures regarding the patent search units (130a, 130b) described in FIG. 2 to FIG. 5b.

[0062] In one embodiment, not only target patent documents directly related to the target paper data, but also target papers that cite the target paper data or are cited by the target paper data are searched first, and target patent documents are searched from the target papers. The target papers are papers that cite or are cited by the target paper data, and it is evident that the author or sponsoring institution is interested in the technical content of the target paper data, and they have technical significance as the technical content of the target paper data has been, for example, supplemented, improved, refuted, or replaced. Accordingly, according to one embodiment of the present invention, optimal target patent documents can be obtained from the target papers to generate technical analysis information, such as the transfer of the technology of interest, the status of disputes related to the technology of interest, and commercialization portfolio strategies and product commercialization strategies using the technology of interest. In particular, if there are subject differences between the aforementioned subject paper data and the aforementioned target paper in terms of the authors, affiliated institutions, and / or sponsoring organizations, the subject paper data and the aforementioned target paper can be considered to have been published by competing research groups or institutions, and the aforementioned target patent literature detected from the aforementioned target paper constitutes the patent literature of the competing research group or institution. Therefore, by analyzing the patent literature of the competing research group or institution derived in this manner, technical analysis information such as the status of technology transfer and disputes possessed by the competing research group or institution, as well as portfolio strategies and commercialization strategies through claim analysis, can be obtained.

[0063] In addition, according to one embodiment of the present invention, by utilizing a new search method or route in the form of citation relationships of papers, an advantage is provided in that important patent documents that are not searchable due to differences in terminology can be searched without omission by searching for papers by others that express the technology of interest using different terms and by finding patent documents that include the terms of said papers by others.

[0064] In one embodiment, the citation relationship paper search unit (350) may search for the target paper data or the target paper information by accessing a citation relationship database unit that stores citation and cited information between multiple paper data in the form of metadata as a non-limiting example. The citation relationship database unit may include Web of Science, Scopus, Google Scholar, or crossreference ( https: / / www.crossref.org / It may be a database stored in an external storage or internal storage of a patent search application device (300a), such as a commercial paper website. For example, if provided by the commercial paper website, it can be accessed via the Internet; if provided by an external storage, it can be connected via a network; and if it exists in an internal storage, it can be accessed via wiring such as a bus.

[0065] In another embodiment, the citation relationship database may include information regarding the impact factor (IF) of each of the plurality of paper materials. The impact factor is an indicator that evaluates the importance of a journal by analyzing the number of times the journal in which the paper material is published has been cited, and the impact factor may serve as a criterion for evaluating the value of the paper material in academia or industry. For example, the citation relationship paper search unit (350) may assign weights to paper materials published in journals with high impact factors among the searched target paper materials, and the weights may serve as a criterion for evaluating the importance of the searched target patent documents.

[0066] In another embodiment, the target paper information and the citation-related paper information may include the title of the target paper material, the author, the first author of the paper, the affiliation of the author or the first author, a link to the paper site, an abstract, keywords, the text, information of the sponsoring organization, ORCID (open researcher and contributor ID), the name of the society or journal, the publication date, a Digital Object Identifier (DOI), an International Standard Serial Number (ISSN), a CAS registration number, automatically recommended keywords added by the paper information generation unit, synonyms of the automatically recommended keywords, deep learning, artificial intelligence (AI), or at least one of the frequently occurring nouns of the citation-related paper material. In yet another embodiment, if the target paper material is published by co-authors, the information of all authors included in the co-authors or the information of authors of a certain rank or higher may be included in the target paper information. Additionally, the information of the affiliation and sponsoring organization may include the names, unique numbers, addresses, and names of the representatives of the organizations. The names of the above-mentioned academic societies and journals may be stored as full names or English abbreviations, and may or may not distinguish between uppercase and lowercase letters. Additionally, regarding the descriptions of the automatic recommendation keywords, synonyms of the automatic recommendation keywords, deep learning, artificial intelligence (AI), or frequently occurring nouns in the citation-related paper data among the above-mentioned target paper information, the disclosures regarding the second paper information (PI2) described above in FIG. 2 may be referenced, provided they are not contradictory.

[0067] In one embodiment, the citation relationship paper search unit (350) defines the paper data that directly cites / is cited as the first generation citation / cited paper data, defines the paper data that indirectly cites / is cited by citing / is cited by the first generation citation / cited paper data as the second generation citation / cited paper data, and defines the paper data that indirectly cites / is cited by citing / is cited by the n-1 generation citation / cited paper data as the nth generation citation / cited paper data, and may further include a citation generation setting unit that can search by setting the target paper data as the nth generation citation / cited paper data by specifying a predetermined value of n. The predetermined value of n may be a natural number greater than 1. The predetermined value of n may be received from the client terminal device (200), may be set as a default value, and the patent search application device (100) may automatically set an appropriate value. For example, the value of n can be automatically set so that the above target paper data has fewer than 200 search results.

[0068] In another embodiment, the author, affiliated institution, and / or sponsoring institution of the target paper material may be a different paper material with a different author, affiliated institution, and / or sponsoring institution. Each researcher may cite their prior research paper material in subsequent research, and when searching for a target paper material that has a citation or citation relationship with the target paper material, the author of the target paper material and the author of the target paper material may be the same or different. If the authors are different, the different authors may be competitors possessing the same technology of interest, and the research and business trends of the competitors can be analyzed and benchmarked through the analysis results of the patent technology analysis unit (340). Furthermore, the analysis results may serve as important data for preventing technology infringement or designing avoidance of the technology by analyzing the patent claims of the competitor's target patent.

[0069] Referring to FIG. 6b, the patent search application device (300b) may include an interface unit (310), a paper information generation unit (320), a patent search unit (330), a patent technology analysis unit (340), and a citation relationship database unit (350). The patent search application device (300b) may further include a paper information generation unit that generates second paper information (PI2) based on information extracted from first paper information (PI1), and the second paper information (PI2) may include at least one of the following: the title of the input paper data extracted from the target paper data by the paper information generation unit (320), the author, the first author of the paper, the affiliation of the author or the first author, a link to the paper site, an abstract, keywords, the text, information of the sponsoring institution, ORCID (open researcher and contributor ID), the name of the academic society or journal, the date of publication, a digital object identifier (DOI), an international standard serial number (ISSN), a CAS registration number, an automatically recommended keyword added by the paper information generation unit (320), a synonym of the automatically recommended keyword, deep learning, artificial intelligence (AI), or frequently occurring nouns of the paper data. The description of the paper information generation unit (320) and the second paper information (PI2) may refer to the disclosures regarding the paper information generation unit (120) and the second paper information (PI2) described above in FIG. 2, provided they are not contradictory.

[0070] In one embodiment, the patent search unit (330) may search for a second target patent document related to the first paper information (PI1) or the second paper information (PI2). By searching for the first target patent document related to the target paper data as well as the second target patent document related to the target paper data in the patent search unit (330), patent documents related to the technology of interest can be efficiently searched. Additionally, for example, the first target patent document and the second target patent document may be output to the client terminal device (200) together without being separated, or the first target patent document may be output together with the target paper data and the second target patent document may be output together with the target paper data.

[0071] In another embodiment, the patent search unit (330) may prioritize outputting a patent document (hereinafter referred to as "common patent document") that is commonly included in the first target patent document and the second target patent document at the top of the search results. The common patent document may be a patent document that contains at least one patent information identical or similar to the paper information of the target paper data that is in a citation relationship with the target paper data. The common patent document may have a high degree of relevance to the technology of interest by having a common relevance to the target paper data and the target paper data. Additionally, as an example, identification information such as the title and author of the target paper data and the target paper data may be displayed together with the common patent document on the client terminal device (200).

[0072] In another embodiment, weights may be assigned to the target paper data and a second target patent document related to the target paper data according to the number of target paper data. A large number of target paper data may imply that the target technology of the target paper data is a subject of interest to many researchers, research institutions, and competitors. Recently, due to public institutions' patent application promotion programs, a massive amount of patent applications or patents are being produced, and there is a growing need to select the patent applications or patents that include future value technologies, such as technologies that are not currently in use but have high future value, and source technologies that can be utilized in other industries in the future. Accordingly, by assigning the weights to the second patent document and performing patent technology analysis based on the weights, useful information for selecting the future value technologies can be generated. In yet another embodiment, when assigning the weights, a predetermined value of n set in the aforementioned citation generation setting unit may be specified together. For example, even if the number of target paper data is the same, when the value of n is 1, the target technology may become a greater subject of interest to the researchers, research institutions, and competitors compared to when the value of n is 5. Accordingly, applications such as setting the value of n to 5 or higher when selecting basic research that is of interest for a long period, and setting the value of n to 1 when selecting new technology that is of interest for a short period, are possible.

[0073] In one embodiment, the patent search application device (300b) may further include a patent technology analysis unit (340) that extracts identical or similar items from the first paper information (PI1) and the target paper information to generate a result of analyzing the literature relationship between the target paper data and the target paper data, and generates technology analysis information including at least one of the following: whether the applicant of the first target patent documents has changed, whether there is a joint application, whether ownership has been transferred, whether a license has been granted, identification information of the successor to the application rights, identification information of the joint applicant, identification information of the assignee, identification information of the licensee, remaining period, filing date, number of family applications, and information regarding the country, or whether there is a dispute. In another embodiment, the patent technology analysis unit (340) may generate meaningful technology analysis information depending on the type of search field of the identical or similar items. For example, if the first author or the institution affiliated with the first author is the same or similar, the technologies in the first target patent document may be the first author's prior or subsequent research technologies; if the information of the sponsoring institution is the same or similar, the sponsoring institution may know the field of technology of interest; and if the name of the academic society or journal is the same or similar, the technology of interest that the academic society or journal is focusing on may be known. In addition, the description of the technology analysis information may refer to the disclosures regarding the patent technology analysis section (140) described above in FIG. 2, provided there is no contradiction.

[0074] In another embodiment, the patent technology analysis unit (340) may assign the document relationship analysis result and the technology analysis information to the first target patent document and output information of the target technology including the document relationship analysis result and the technology analysis information in a time-series manner. The information may be output through the client device (200) in the form of a web page screen, saved information of an account on a specific website, or a report in the format of an Excel or Word file. However, the aforementioned formats are exemplary and are not limited to a specific format. By outputting the citation relationship analysis result and the technology analysis information in a time-series manner, the patent search application device (300b) may provide useful information for technology transfer information of the technology of interest, a portfolio for commercialization of the technology of interest, and a commercialization strategy.

[0075] In one embodiment, the patent search application device (100) may further include a comprehensive result output unit that outputs identification information of the searched paper data or patent documents, original files, information of the paper data or patent documents, results of the analysis of the relationship between the documents, technical analysis information, or a combination thereof, and the searched paper data or patent documents may include the target paper data, the first target patent document, or the second target patent document. For example, when receiving paper information regarding the target paper data through a client terminal (200), the comprehensive result output unit may output patent documents related to the target paper data, paper data that has a citation or citation relationship with the target paper data, and patent documents related to the paper data all at once. Accordingly, by outputting search results that encompass not only simple patent searches but also research data related to the technology of interest, comprehensive technical information such as information on research institutions related to the technology of interest, information on sponsoring institutions, information on researchers, inventors, and applicants of the technology of interest, trends in the technical field to which the technology of interest belongs, and business fields of related companies can be provided. In addition, in another embodiment, if a patent technology analysis unit (140) is further included, the results of the literature relationship analysis or the technology analysis information provided by the patent technology analysis unit (140) may be further included. In one embodiment, the comprehensive result output unit may arrange the paper materials according to the order of the impact factor of the plurality of paper materials mentioned above in the citation relationship paper search unit (350) of FIG. 6a. In addition, the patent search unit (300) may receive information regarding the weights assigned to the patent documents and arrange the patent documents according to the weights.

[0076] In one embodiment, the patent search unit (330) may classify the first target patent document as a competing technology if the target paper data cites the target paper data, and classify the first target patent document as a potentially infringing technology if the target paper data cites the target paper data. If the target paper data cites the target paper data, it is highly likely that the technology of the first target patent document searched by the target paper data is a competing technology, a similar technology, or an avoidance technology of the technology of interest of the target paper data. If the target paper data cites the target paper data, it is highly likely that the technology of interest infringes the technology of the first target patent document. By classifying the first target patent document according to the citation or citation relationship of the paper data, a direction for establishing a commercialization portfolio strategy for the technology of interest can be provided.

[0077] In another embodiment, the patent search unit (340) may include a first restricted search unit (SC1) that searches for the first target patent document filed within the period during which exceptions to public notice can be claimed of the target paper material, or a second restricted search unit (SC2) that searches for the first target patent document filed within a period before or after the submission or publication date of the target paper material. For the description of the first restricted search unit (SC1) and the second restricted search unit (SC2), reference may be made to the disclosures described above in FIG. 3, provided there is no contradiction.
