Description

This disclosure relates to a support device for figurative trademark searches, a method for supporting figurative trademark searches, a computer program, and a computer-readable medium on which the computer program is stored.

Patent Document 1 discloses a similar image search device that automatically assigns a Vienna classification code (an example of classification information) to a new trademark by inputting it into a pre-trained model.

Japanese Patent Publication No. 2020-144440

For example, when investigating whether there are identical or similar prior trademarks for a figurative trademark intended for application, the investigation is conducted using the Vienna Classification code. Generally, searching for figurative trademarks using only one Vienna Classification code often results in the detection of a vast number of prior trademarks. In this case, it is undesirable because many of the detected prior trademarks may appear dissimilar to the figurative trademark intended for application at a glance. On the other hand, combining many Vienna Classification codes in the search for figurative trademarks reduces the number of prior trademarks detected. However, combining more Vienna Classification codes than necessary increases the likelihood of missing some trademarks. Therefore, when conducting a search for figurative trademarks, the user should select several Vienna Classification codes that seem relevant to the figurative trademark intended for application, and then combine a few of these codes to conduct the search. In other words, when searching for figurative trademarks, it is necessary to use multiple Vienna Classification codes that are appropriate both in content and quantity. Furthermore, it is conceivable to conduct a search for figurative trademarks using a device that automatically assigns Vienna Classification codes, such as the device described in Patent Document 1, but it is difficult to conduct a search that reflects the user's search perspective with such a device. In particular, because the internal processes, such as the automatic assignment of Vienna classification codes, are often black boxes in such devices, it is difficult for users to understand the perspectives from which the surveys conducted by the device were conducted.

This disclosure aims to provide a support device for figurative trademark searches, a support method for figurative trademark searches, a computer program, and a computer-readable medium that can assist in conducting searches of figurative trademarks using multiple appropriate classification information while reflecting the user's research perspective.

A support device for searching for figurative trademarks in one aspect for achieving the above objective is:
At a minimum, an input unit for inputting image data of the figurative trademark to be investigated and multiple classification information used for the investigation of the figurative trademark,
A calculation unit calculates a matching score for each classification information based on the image data input to the input unit and a reference figure corresponding to the classification information input to the input unit.
The system includes an acquisition unit that acquires prior-filed trademarks from a trademark database that include multiple classification information whose matching score is equal to or greater than a first predetermined value.

Furthermore, a method for supporting a figurative trademark search in order to achieve the above objective is:
A method for supporting a graphic trademark search performed by computer,
At a minimum, the process involves inputting image data of the figurative trademark to be investigated and multiple classification pieces of information used for the investigation of the figurative trademark.
A step of calculating a degree of agreement score for each classification information based on the input image data and the reference figure corresponding to the input classification information,
The step of obtaining prior-filed trademarks from a trademark database that include multiple classification information whose matching score is equal to or greater than a first predetermined value.

Furthermore, a computer program relating to one aspect for achieving the above objective is:
A computer program comprising at least one instruction executed by the processor of a support device for figurative trademark searches,
When at least one of the instructions is executed by the processor, the support device shall,
Based on the image data input to the input unit of the support device and the reference figures corresponding to the multiple classification information input to the input unit, a matching score is calculated for each classification information.
The system retrieves prior-filed trademarks from a trademark database that include multiple classification information whose matching score is equal to or greater than a first predetermined value.

Furthermore, a computer-readable medium relating to one embodiment for achieving the above objective includes:
The above computer program is stored.

According to the figurative trademark search support device described above, a degree of similarity score is calculated for each classification information based on a reference figure corresponding to multiple input classification information. Prior-filed trademarks containing multiple classification information with a degree of similarity score equal to or greater than a first predetermined value are then retrieved from the trademark database. In other words, the degree of similarity score calculated by the support device described above is based on multiple classification information input by the user, and the degree of similarity score for the multiple classification information used to retrieve prior-filed trademarks from the trademark database is equal to or greater than the first predetermined value. Therefore, such a figurative trademark search support device can assist in conducting figurative trademark searches using multiple appropriate classification information while reflecting the user's search perspective. Furthermore, similar effects can be achieved with the information processing method, computer program, and computer-readable media described above.

This disclosure provides a support device for searching figurative trademarks, a method for searching figurative trademarks, a computer program, and a computer-readable medium that can assist in searching figurative trademarks using multiple appropriate classification information while reflecting the user's search perspective.

An example of an embodiment of this disclosure will be described below with reference to the drawings.

The support system 1 of this embodiment will be described with reference to Figures 1 and 2. Figure 1 is a block diagram of the support system 1 according to one embodiment of this disclosure. The support system 1 is a support system for figurative trademark searches. Figure 2 is a diagram illustrating a reference figurative database 40. As illustrated in Figure 1, the support system 1 includes a trademark database 10, a support device 20, and a user terminal device 30. The trademark database 10 and the support device 20 can communicate with each other, for example, via the Internet. The support device 20 and the user terminal device 30 can communicate with each other via wired or wireless means.

The trademark database 10 is, for example, the database of the Japan Patent Office, the database of the United States Patent and Trademark Office, the database of the World Intellectual Property Organization (WIPO), or a commercial database provided by a trademark service provider. The trademark database 10 stores application and registration information for trademarks in at least one country. In this embodiment, the term "country" includes not only independent countries but also countries not internationally recognized and organizations consisting of multiple countries such as the European Union. Furthermore, application information for trademarks includes, for example, information on trademark registration applications, international registration applications, trademark registration applications, etc. In this embodiment, trademark registration applications also include international trademark registration applications. In other words, in this embodiment, the term "trademark registration application" includes not only applications filed directly with designated offices such as patent offices and trademark offices of each country, but also applications filed indirectly with designated offices of each country through international trademark applications. For example, the Japan Patent Office's database stores information related to trademark applications and registrations filed with the Japan Patent Office, including trademarks, classes, designated goods and services, similarity group codes, Vienna Classification codes, applicant names, right holder names, application numbers, registration numbers, application dates, and registration dates. Note that the Vienna Classification code is an example of classification information.

The support device 20 comprises an input unit 21, a control unit 22, an acquisition unit 23, a display unit 24, and an output unit 25. These are interconnected via a bus 26, enabling communication between them.

The input unit 21 is configured to receive user input operations to the support device 20 and to generate a request signal corresponding to those input operations. The input unit 21 is, for example, a touch panel superimposed on the display unit 24, or an input device such as a keyboard electrically connected to the support device 20. The input unit 21 receives, for example, image data of the figurative trademark to be investigated and multiple classification information used for the figurative trademark investigation. However, other information besides the image data of the figurative trademark to be investigated and the multiple classification information used for the figurative trademark investigation may also be input to the input unit 21. Once the image data of the figurative trademark to be investigated and the multiple classification information used for the figurative trademark investigation are input to the input unit 21, the input unit 21 transmits the input image data and the multiple classification information to the control unit 22.

The control unit 22 comprises a memory and a processor as its hardware configuration. The memory consists of, for example, a ROM (Read Only Memory) storing various computer programs, and a RAM (Random Access Memory) having multiple work areas where various computer programs executed by the processor are stored. The processor is, for example, a CPU (Central Processing Unit) configured to load a specified computer program from the various computer programs embedded in the ROM onto the RAM and execute various processes in cooperation with the RAM. The control unit 22 comprises a storage unit 221, a specification unit 222, a calculation unit 223, a determination unit 224, and a generation unit 225.

In this embodiment, computer-readable media may be used. Computer-readable media refers to any type of physical memory (RAM, ROM, etc.) capable of storing information and data that a processor can read. Computer-readable media can store instructions related to execution by one or more processors. The term "computer-readable media" encompasses tangible items and excludes carrier waves and transient signals (i.e., refers to non-transient media). Examples of non-transient computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R/Ws, and semiconductor memory (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), and flash ROMs).

The memory unit 221 stores reference figures associated with each classification information. In this embodiment, the memory unit 221 stores a reference figure database 40 illustrated in Figure 2. The reference figures can be arbitrarily set by the user, as long as they correspond to the Vienna Classification code. In other words, the reference figures are not figures corresponding to the Vienna Classification codes actually assigned to trademarks filed by designated offices such as national patent offices and trademark offices, but rather figures arbitrarily set by the user. The dimensions, orientation, size, etc., of the reference figures set by the user are arbitrary. Furthermore, the term "user" here does not include designated offices such as national patent offices and trademark offices, or service providers related to trademarks. Therefore, in this embodiment, the reference figures are not set by designated offices such as national patent offices and trademark offices, or service providers related to trademarks. Also, the reference figures do not have to be set based on the Vienna Classification codes actually assigned to trademarks filed. Moreover, the reference figures may be figures that include only graphic elements linked to only one Vienna Classification code (an example of classification information). The simpler the composition of a graphic, the fewer Vienna Classification codes tend to be assigned to it. Therefore, a trademark consisting solely of graphic elements linked to only one Vienna Classification code is likely to be considered extremely simple and commonplace. Since extremely simple and commonplace trademarks lack distinctiveness, a graphic containing only graphic elements linked to only one Vienna Classification code is highly likely to be considered a non-distinctive graphic. In this embodiment, the reference graphic corresponding to Vienna Classification code 1.7.6 is, for example, graphic D1 located in area R1 in Figure 2. Graphic D1 is a crescent-shaped graphic. For explanatory purposes, only one reference graphic corresponding to each Vienna Classification code is shown in Figure 2; however, there may be multiple reference graphics corresponding to each Vienna Classification code.

The classification information is, for example, the Vienna Classification Code. In this embodiment, the classification information includes major, medium, and minor classifications. However, the classification information only needs to include the major classification; for example, it does not need to include the medium and minor classifications. For example, if the classification information is the Vienna Classification Code, the Vienna Classification Code has a tree structure of major, medium, and minor classifications, consisting of 29, 144, and 1887 classifications, respectively. For example, Major Classification 1 is a classification related to celestial bodies, natural phenomena, and maps. Medium Classification 1.7 is a classification related to the moon. Minor Classification 1.7.6 is a classification related to crescent moons and half moons.

Returning to Figure 1, let's explain the identification unit 222. The identification unit 222 identifies a reference figure corresponding to each of the multiple classification information input into the input unit 21. For example, if the Vienna classification code 1.7.6 is input into the input unit 21, the identification unit 222 identifies the reference figure (figure D1) within area R1. If there are multiple reference figures corresponding to the Vienna classification code input into the input unit 21 (for example, if there are multiple reference figures within area R1), the identification unit 222 identifies these multiple reference figures.

The calculation unit 223 calculates a degree of agreement score for each input classification information based on the image data input to the input unit 21 and the reference figure corresponding to the classification information input to the input unit 21. The calculation unit 223 searches for a figure identical to the reference figure (hereinafter also referred to as "identical figure") or a figure similar to the reference figure (hereinafter also referred to as "approximate figure") from among the figurative trademarks related to the image data input to the input unit 21. In this embodiment, an identical figure is a figure with a 100% agreement rate with the reference figure, and an approximate figure is a figure with an agreement rate of 20% or more but less than 100% with the reference figure. However, the definition of an approximate figure is not limited to this. For example, a figure with an agreement rate of 50% or more but less than 100% with the reference figure may be defined as an approximate figure. The calculation unit 223 calculates a degree of agreement score for each input classification information based on the agreement rate between the searched identical or approximate figure and the reference figure. The degree of agreement score is an index that shows the degree of agreement between all or part of the figurative trademark related to the image data input to the input unit 21 and the reference figure. For example, if both are identical (i.e., the agreement rate is 100%), the agreement score is 100. If the agreement rate is 50%, the agreement score is 50. Thus, the more similar the two are (i.e., the higher the agreement rate), the higher the agreement score.

The determination unit 224 determines a combination of classification information using multiple classification information whose matching score calculated by the calculation unit 223 is equal to or greater than a first predetermined value. In this embodiment, the first predetermined value is 50. However, the first predetermined value may be between 0 and 100, and is not limited to 50. The determination unit 224 combines two or more Vienna classification codes with different major classifications. That is, the determination unit 224 does not combine Vienna classification codes with the same major classification, such as Vienna classification code 26.3.2 and Vienna classification code 26.3.2. The determination unit 224 transmits the determined combination of classification information to the acquisition unit 23.

The acquisition unit 23 acquires prior-filed trademarks from the trademark database 10 that include multiple classification information with a matching score equal to or greater than a first predetermined value, based on the combination received from the determination unit 224. The acquisition unit 23 transmits the acquired prior-filed trademark information to the generation unit 225. The prior-filed trademark information includes at least the application number, registration number, and Vienna Classification code related to the prior-filed trademark. However, the prior-filed trademark information may also include other information such as the trademark, class, designated goods and services, similarity group code, applicant name, right holder name, application date, registration date, and status related to the prior-filed trademark. In this embodiment, the prior-filed trademark information includes the applicant name, right holder name, application number, registration number, trademark, and Vienna Classification code related to the prior-filed trademark.

The generation unit 225 generates similarity information for each prior trademark acquired by the acquisition unit 23, based on the classification information (in this embodiment, the Vienna Classification Code) included in the prior trademark acquired by the acquisition unit 23 from among the multiple classification information input to the input unit 21. In other words, the generation unit 225 generates similarity information for each prior trademark acquired by the acquisition unit 23, based on the multiple classification information included in the combination used by the acquisition unit 23 when acquiring the prior trademark. In this embodiment, the generation unit 225 generates similarity information based only on the degree of agreement score related to the classification information for which a degree of agreement score has been calculated. As an example, similarity information related to a prior trademark acquired by the acquisition unit 23 based on a combination consisting of Vienna Classification Code 1.7.6 and Vienna Classification Code 23.1.5 will be described. In this case, the matching score for Vienna Classification code 1.7.6 is assumed to be 80, and the matching score for Vienna Classification code 23.1.5 is assumed to be 50. In this case, the generation unit 225 generates similarity information indicating that the similarity between the acquired prior trademark and the figurative trademark under investigation is 65 (= (80 + 50) / 2). Thus, the similarity in this embodiment is the average value of multiple matching scores related to multiple classification information included in the combination used by the acquisition unit 23 when acquiring the prior trademark. However, the similarity is not limited to the average value of multiple matching scores related to multiple classification information included in the combination used by the acquisition unit 23 when acquiring the prior trademark. In this embodiment, the generation unit 225 generates similarity information without considering the similarity of the designated goods and services. This is because, for example, the designated goods and services are not necessarily determined at the pre-filing search stage. However, the generation unit 225 may also consider the similarity of the designated goods and services when generating similarity information.

The generation unit 225 generates display data based on the prior trademark information received from the acquisition unit 23 and the similarity information generated by the generation unit 225. The display data generated by the generation unit 225 includes the prior trademark related to the prior trademark information received from the acquisition unit 23, and the similarity score for that prior trademark. The generation unit 225 transmits the generated display data to the display unit 24 or output unit 25.

The display unit 24 is, for example, a touchscreen display such as a liquid crystal display or an organic EL display. The display unit 24 is configured to display, for example, display data received from the generation unit 225.

The output unit 25 outputs the display data received from the generation unit 225 to the user terminal device 30.

The user terminal device 30 is a terminal device operated by the user of the support device 20. The user terminal device 30 is, for example, an electronic device such as a desktop PC, notebook PC, tablet terminal, or smartphone. The user terminal device 30 includes a display unit 31. The display unit 31 is, for example, a liquid crystal display. The display unit 31 is configured to display, for example, display data output from the output unit 25.

Next, referring to Figures 3 to 6, the processing related to the support method for figurative trademark searches performed by the support device 20 will be described. In order to easily reflect the user's search perspective in the figurative trademark search, the reference figure in this embodiment is a figure arbitrarily set by the user. Furthermore, to clarify the search perspective for figurative trademark searches, the reference figure in this embodiment is a figure containing only figurative elements linked to only one classification information (Vienna Classification code). Figure 3 is a flowchart illustrating the processing performed by the support device 20 in this embodiment.

As illustrated in Figure 3, the user inputs image data of the figurative trademark to be investigated and multiple classification information into the input unit 21 (STEP 01). Figure 4 shows an example of the input screen in this embodiment. As illustrated in Figure 4, in this embodiment, the user inputs image data of the figurative trademark 100 and multiple classification information (Vienna Classification codes 1.7.6, 23.1.5, 26.3.2, 26.4.2, and 26.4.3). The figurative trademark 100 includes a crescent moon shape 110 and a rhombus shape 120. The rhombus shape 120 includes a first triangular shape 121 and a second triangular shape 122. The input unit 21 transmits the input image data and multiple classification information to the control unit 22.

As illustrated in Figure 3, the identification unit 222 identifies a reference figure corresponding to each of the multiple classification information received from the input unit 21 (STEP 02). In this embodiment, since the input unit 21 receives Vienna classification codes 1.7.6, 23.1.5, 26.3.2, 26.4.2, and 26.4.3, the identification unit 222 identifies a reference figure corresponding to these Vienna classification codes (for example, figure D1 as illustrated in Figure 2) for each Vienna classification code. If there are multiple reference figures corresponding to the classification information (Vienna classification codes) input to the input unit 21, the identification unit 222 identifies multiple reference figures.

As illustrated in Figure 3, the calculation unit 223 calculates a matching score for each classification information input to the input unit 21 based on the image data input to the input unit 21 and the reference figures identified by the identification unit 222 (STEP 03). If multiple reference figures are identified for a single classification information, the calculation unit 223 calculates a matching score for each reference figure and determines the highest matching score among them as the matching score corresponding to that classification information.

For example, regarding Vienna Classification Code 1.7.6, the calculation unit 223 searches for the moon figure 110 among the figurative trademarks 100. The calculation unit 223 compares the moon figure 110 with figure D1 and determines the degree of similarity in their external shapes. In this embodiment, the degree of similarity between the moon figure 110 and figure D1 is assumed to be 80%. Since the degree of similarity between the moon figure 110 and figure D1 is 80%, the moon figure 110 is an approximate figure. As illustrated in Figure 5, the calculation unit 223 calculates a similarity score of 80 as the similarity score for Vienna Classification Code 1.7.6.

Furthermore, for example, in the case of Vienna Classification code 26.3.2, the calculation unit 223 searches for a rhombus figure 120 that includes the first triangular figure 121 and the second triangular figure 122 from among the figurative trademark 100. The calculation unit 223 compares the rhombus figure 120 with figure D3 (see Figure 2) and determines the degree of agreement between the external shapes of the rhombus figure 120 and figure D3. In this embodiment, the degree of agreement between the rhombus figure 120 and figure D3 is assumed to be 90%. Since the degree of agreement between the rhombus figure 120 and figure D3 is 90%, the rhombus figure 120 is an approximate figure. As illustrated in Figure 5, the calculation unit 223 calculates a degree of agreement score of 90 as the degree of agreement score for Vienna Classification code 26.3.2. Using a similar principle, the calculation unit 223 also calculates the degree of agreement scores for Vienna Classification codes 23.1.5, 26.4.2, and 26.4.3. In this embodiment, the matching score for Vienna classification code 23.1.5 is 50. The matching score for Vienna classification code 26.4.2 is 40. The matching score for Vienna classification code 26.4.3 is 60. The calculation unit 223 transmits the calculated matching score to the determination unit 224.

As illustrated in Figure 3, the determination unit 224 determines a combination using multiple classification information whose matching score is equal to or greater than a first predetermined value (STEP 04). In this embodiment, the determination unit 224 determines a combination consisting of two classification information (Wiener classification codes). Also, in this embodiment, the first predetermined value is 50, so the determination unit 224 determines a combination using Wiener classification codes 1.7.6, 23.1.5, 26.3.2, and 26.4.3. Furthermore, the determination unit 224 combines multiple Wiener classification codes that belong to different major classifications. Therefore, the combinations in this embodiment are the combination of Wiener classification code 1.7.6 and Wiener classification code 23.1.5, the combination of Wiener classification code 1.7.6 and Wiener classification code 26.3.2, the combination of Wiener classification code 1.7.6 and Wiener classification code 26.4.3, the combination of Wiener classification code 23.1.5 and Wiener classification code 26.3.2, and the combination of Wiener classification code 23.1.5 and Wiener classification code 26.4.3. The determination unit 224 transmits the determined combination of Vienna classification codes to the acquisition unit 23.

The acquisition unit 23 acquires prior-filed trademarks containing the Vienna Classification code for each combination from the trademark database 10 based on the combination of Vienna Classification codes received from the determination unit 224 (STEP 05). For example, when acquiring prior-filed trademarks from the Japan Patent Office database based on the combination of Vienna Classification code 1.7.6 and Vienna Classification code 26.3.2, the acquisition unit 23 acquires prior-filed trademarks containing both Vienna Classification code 1.7.6 and Vienna Classification code 26.3.2 from the prior-filed trademarks stored in the Japan Patent Office database. The acquisition unit 23 transmits the prior-filed trademark information relating to the acquired prior-filed trademarks to the generation unit 225.

The generation unit 225 generates similarity information for each prior trademark acquired by the acquisition unit 23, based on the Vienna Classification code (an example of classification information) included in the prior trademark information received from the acquisition unit 23 (STEP 06). For example, for a prior trademark acquired based on a combination of Vienna Classification code 1.7.6 and Vienna Classification code 26.3.2, the generation unit 225 generates similarity information indicating that the similarity to the said prior trademark is 85 (= (80 + 90) / 2).

The generation unit 225 generates display data (STEP 07) that includes the prior trademarks acquired by the acquisition unit 23 and the similarity scores related to those trademarks, based on the prior trademark information received from the acquisition unit 23 and the generated similarity information. The generation unit 225 transmits the generated display data to the display unit 24 or output unit 25. When the generation unit 225 transmits the display data to the output unit 25, the output unit 25 outputs the display data received from the generation unit 225 to the user terminal device 30.

When display data is transmitted to the display unit 24 or output to the user terminal device 30, the display data is displayed on the display unit 24 of the support device 20 or the display unit 31 of the user terminal device 30 (STEP 08). As illustrated in Figure 6, in this embodiment, the display data is displayed in a list format on the display unit 24 of the support device 20 or the display unit 31 of the user terminal device 30. The list illustrated in Figure 6 includes three prior-filed trademarks. Note that the list illustrated in Figure 6 displays the application number or registration number of the prior-filed trademark, the applicant or right holder, the trademark, the Vienna Classification code, and the similarity score. However, for example, only some of these may be displayed, or other information (e.g., classification) may be displayed in addition to these. By visually inspecting the display data displayed on the display unit 24 of the support device 20 or the display unit 31 of the user terminal device 30, the user can quickly identify prior-filed trademarks that may be identical or similar to the figurative trademark under investigation.

For example, when investigating whether there are any identical or similar prior trademarks for a figurative trademark that is intended for application, the Vienna Classification code is used for the investigation. Generally, searching for figurative trademarks using only one Vienna Classification code often results in the detection of a huge number of prior trademarks. In this case, it is undesirable because many of the detected prior trademarks may appear to be dissimilar to the figurative trademark intended for application. On the other hand, searching for figurative trademarks using a combination of many Vienna Classification codes reduces the number of prior trademarks detected. However, using more Vienna Classification codes than necessary increases the likelihood of missing some trademarks. Therefore, when conducting a search for figurative trademarks, the user should select several Vienna Classification codes that seem relevant to the figurative trademark intended for application, and then combine a few (for example, two) of these codes to conduct the search. In other words, when searching for figurative trademarks, it is necessary to use multiple Vienna Classification codes that are appropriate both in content and quantity. Furthermore, while it might be possible to conduct a search for figurative trademarks using a device that automatically assigns Vienna Classification codes simply by inputting image data related to the figurative trademark to be filed, such a device makes it difficult to conduct a search that reflects the user's search perspective. In particular, because the internal processing, such as the automatic assignment of Vienna Classification codes, is often a black box in such devices, it is difficult for the user to understand what perspective the search conducted by the device took.

According to the figurative trademark search support device 20 with the above configuration, a degree of similarity score is calculated for each classification information based on the reference figure corresponding to the multiple classification information input, and prior-filed trademarks containing multiple classification information with a degree of similarity score equal to or greater than a first predetermined value are obtained from the trademark database 10. In other words, the degree of similarity score calculated by the support device 20 is based on the multiple classification information input by the user, and the degree of similarity score for the multiple classification information used when obtaining prior-filed trademarks from the trademark database 10 is equal to or greater than the first predetermined value. Therefore, the support device 20 can support the search of figurative trademarks using multiple appropriate classification information while reflecting the user's search perspective. Furthermore, the information processing method, computer program, and computer-readable media related to the above configuration can achieve the same effects as the support device 20.

Furthermore, according to the figurative trademark search support device 20 with the above configuration, the reference figure is a figure containing only figurative elements that are linked to only one classification information. Therefore, there is only one classification information (Vienna Classification code) linked to the reference figure, and multiple classification information is not linked. For this reason, the support device 20 can assist in conducting figurative trademark searches from a clear search perspective.

Furthermore, according to the figurative trademark search support device 20 with the above configuration, the reference figurative figure is a figure arbitrarily set by the user, and therefore does not need to be set based on the Vienna Classification code actually assigned to the trademark application. For this reason, the support device 20 can assist in conducting searches that reflect the user's search perspective.

Furthermore, according to the figurative trademark search support device 20 with the above configuration, the calculation unit 223 generates similarity information indicating the degree of similarity between the figurative trademark and the prior trademark acquired by the acquisition unit 23, based on the multiple classification information included in the prior trademark acquired by the acquisition unit 23 from among the multiple classification information input to the input unit 21. Therefore, by using the similarity information, the user can intuitively recognize prior trademarks that are highly likely to be identical or similar to the figurative trademark being searched.

Furthermore, according to the figurative trademark search support device 20 with the above configuration, the acquisition unit 23 acquires prior-filed trademarks that include two classification information sets with a similarity score of 1 or higher. Generally, using only one classification information set for figurative trademark searches results in an undesirablely large number of acquired prior-filed trademarks. However, using too much classification information for figurative trademark searches can lead to missed trademarks. In this embodiment, considering these circumstances, the acquisition unit 23 is configured to acquire prior-filed trademarks that include two classification information sets with a similarity score of 1 or higher. Therefore, the support device 20 can suppress both the risk of acquiring a large number of prior-filed trademarks, including those that appear dissimilar at a glance, and the risk of missed trademarks.

Furthermore, according to the figurative trademark search support device 20 with the above configuration, the acquisition unit 23 acquires prior-filed trademarks containing multiple classification information with different major classifications from the trademark database 10. Therefore, the support device 20 can assist in conducting figurative trademark searches using more appropriate multiple classification information.

Furthermore, the figurative trademark search support device 20 with the above configuration includes a storage unit 221 that stores reference figures associated with each classification information. The calculation unit 223 calculates a matching score for each classification information based on the image data input to the input unit 21 and the reference figures stored in the storage unit 221 corresponding to the classification information input to the input unit 21. Therefore, the support device 20 can assist in searching for figurative trademarks even if reference figures are not input to the input unit 21; it only requires image data of the figurative trademark to be searched and multiple classification information to be input to the input unit 21. Thus, the support device 20 can reduce the user's input burden.

The embodiments described above are provided to facilitate understanding of this disclosure and do not limit it. This disclosure may be modified or improved without departing from its intent.

In this embodiment, the display data generated by the generation unit 225 includes all prior trademarks acquired by the acquisition unit 23, but it may also include only prior trademarks with a similarity of a second predetermined value or higher. Therefore, in this case, the similarity of the prior trademarks included in the display data generated by the generation unit 225 is a second predetermined value or higher. The second predetermined value is, for example, 60. However, it goes without saying that the second predetermined value is not limited to 60. When the second predetermined value is 60, the display data illustrated in Figure 7 is displayed on the display unit 24 of the support device 20 or the display unit 31 of the user terminal device 30. The display data illustrated in Figure 7 differs from the display data illustrated in Figure 6 in that it does not display the prior trademark related to trademark registration No. 3452689, which has a similarity of 55. Thus, in this example, the generation unit 225 generates display data that includes only prior trademarks with a similarity of a second predetermined value or higher. Therefore, the display data generated by the generation unit 225 includes only prior-filed trademarks that have a reasonably high degree of similarity to the figurative trademark under investigation—that is, prior-filed trademarks that require careful verification. Consequently, with such a support device 20, the user only needs to verify prior-filed trademarks that have a reasonably high degree of similarity to the figurative trademark under investigation. This reduces the burden on the user when verifying acquired prior-filed trademarks and allows the user to efficiently verify acquired prior-filed trademarks.

In this embodiment, the input unit 21 receives image data of the figurative trademark to be investigated and multiple classification information. However, as illustrated in Figure 8, the input unit 21 may also receive image data, multiple classification information, and reference figures corresponding to the classification information. That is, in STEP 01 illustrated in Figure 3, the user may input image data of the figurative trademark to be investigated, multiple classification information, and reference figures corresponding to the classification information into the input unit 21. In this case, the calculation unit 223 calculates a matching score for each classification information based on the image data and reference figures input into the input unit 21. Therefore, even if the reference figure database 40 is not stored in the storage unit 221, the support device 20 can assist in investigating figurative trademarks using multiple appropriate classification information while reflecting the user's investigation perspective.

In the above embodiment, the list illustrated in Figure 6 includes three prior-filed trademarks, but the number of prior-filed trademarks included in the list may be less than three or four or more.

In the above embodiment, an example using the Vienna Classification Code as classification information was explained, but classification information other than the Vienna Classification Code may also be used.

In the above embodiment, the determination unit 224 determines a combination consisting of two Vienna classification codes, but the determination unit 224 may also determine a combination consisting of three or more Vienna classification codes.

In the above embodiment, the generation unit 225 generates similarity information indicating the degree of similarity between the prior-filed trademark acquired by the acquisition unit 23 and the figurative trademark under investigation. However, it is not necessary to generate similarity information.

In the above embodiment, the acquisition unit 23 acquires prior-filed trademarks containing multiple classification information with different major classifications from the trademark database 10. However, it may also acquire prior-filed trademarks containing multiple classification information with the same major classification from the trademark database 10.

In the above embodiment, the support device 20 may include a storage device 27, as shown by the dashed line in Figure 1. The storage device 27 is, for example, a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory. The storage device 27 is configured to store programs and various data, and may store the reference graphic database 40. If the reference graphic database 40 is stored in the storage device 27, the storage device 27 is an example of a storage unit. In this case, the reference graphic database 40 does not need to be stored in the storage unit 221. Furthermore, the reference graphic database 40 may be stored in an external database. In this case, the support device 20 obtains multiple reference graphics corresponding to multiple classification information input to the input unit 21 from the external database.

In the above embodiment, the reference figure is a figure arbitrarily set by the user, but it may also be a figure set by a party other than the user. A party other than the user might be, for example, a service provider related to trademarks. Even in this case, it is preferable that the reference figure be set by a party other than the designated government office, such as the patent office or trademark office of each country.

In the above embodiment, the reference figure is a figure containing only a graphic element linked to only one classification piece of information; however, it may also be a figure containing graphic elements linked to two or more classification pieces of information.

In the above embodiment, the acquisition unit 23 acquires the prior-filed trademark from the Japan Patent Office database, but it may also acquire the prior-filed trademark from other trademark databases, such as the United States Patent and Trademark Office database.
