However, in the drawing of the searched patent document, it is difficult to determine where the part corresponding to the keyword the user is looking for is located. In addition, in order to understand the drawings, detailed descriptions of the invention such as descriptions of symbols should be looked at.

Therefore, in order to solve such a problem, a technique for extracting explanations for reference numerals in drawings [Patent Document 1] and a technique for displaying explanations for reference numerals in drawings are proposed [Patent Documents 2 and 3]. In particular, in the prior arts, reference numeral descriptions are indicated at positions where reference numerals are recognized in the drawings.

However, in the prior art, since only descriptions of reference signs, such as names, are described, more detailed descriptions of the reference signs are lacking. A more specific description of the reference numerals in the drawings is set forth in the detailed description of the patent document or in the claims.

Therefore, it is necessary to display a detailed description of the drawings (or descriptions of reference numerals) together with the drawings or the contents of the claims.

More specifically, the patent reading server 50 is a server that provides a reading service of patent documents, holds patent documents, and provides an interface for searching, reading, and the like of patent documents.

Patent documents refer to published patent publications or registered patent publications. Patent documents may include not only patents but also utility models. Since a utility model has almost the same items as the Patent Gazette except for the content of the rights, the utility model Gazette is also included when referring to the patent document hereinafter. Meanwhile, patent documents include both domestic and foreign patent publications. That is, all patent publications issued by each country's patent offices or WIPO may apply.

In addition, the patent document is divided into detailed items such as bibliography, claims, detailed description, and drawings and stored. In addition, since the patent document is managed separately as data for each detailed item, it is configured so that it can be searched for or referenced by the corresponding item.

In particular, in the patent document, drawings are stored and managed as images (hereinafter referred to as drawing images) for each degree, and other bibliographic items, detailed descriptions, and claims are stored and managed as texts. Accordingly, text search is provided for items such as detailed description and claims. In addition, the bibliography is composed of patent number, IPC classification, applicant, inventor, filing date, etc., and searches are provided for each of these items.

In particular, the patent reading server 50 provides a service for reading a drawing of a patent document, and provides an interface for this. At this time, the patent reading server 50 interworks with the drawing display system 30 to provide a service for processing and displaying the drawings. In particular, on the screen displaying the drawings, descriptions of reference numerals are added and the contents of the specification related to the reference numerals are displayed together with the drawings.

On the other hand, preferably, the patent reading server 50 is provided as a web service on the web. Accordingly, the user accesses the patent browsing server 50 through the user terminal 10 and uses the patent browsing service.

In addition, the patent reading server 50 may be implemented as a server-client system in conjunction with a client (not shown) installed in the user terminal 10 to provide a patent reading service. That is, a dedicated patent browsing client (or a dedicated application) is installed in the user terminal 10 , and the patent browsing service can be used in conjunction with the patent reading server 50 through the client. In particular, when the user terminal 10 is a mobile terminal, the client may be a mobile application (application, app) or the like.

Next, the user terminal 10 is a computing terminal used by the user, and is a typical computing terminal such as a PC, a notebook computer, a netbook, a PDA, a smart phone, or a mobile.

The user accesses the patent reading server 50 through the user terminal 10 and uses services such as patent search and patent document reading. Since the user uses a service such as reading a patent document through the user terminal 10 , it is hereinafter interpreted that the user performs a certain task is performed by the user terminal 10 .

Also, preferably, a web browser (not shown) or a dedicated client is installed in the user terminal 10 , and the patent browsing server 50 is accessed by these client program systems to use the patent browsing service.

In addition, commands for patent reading input by the user are inputted from the user terminal 10 , these commands are transmitted to the patent reading server 50 , and the results returned from the patent reading server 50 are returned to the user terminal 10 . displayed on the screen of However, the corresponding screen is a screen made by the patent reading server 50 or by data provided by the patent reading server 50 . Hereinafter, it will be described that the result is displayed on the screen for convenience.

Next, the drawing display system 30 is implemented as a server system or web application on a network, interlocked with the patent reading server 50, or implemented as a system of an accessory function.

In particular, the drawing display system 30 processes the drawing of the patent document and displays it on the screen. That is, the drawing display system 30 recognizes the reference numerals in the drawings of the patent document, extracts the description of the reference numbers from the content of the patent document, and arranges the description of each reference number in the margin of the drawing. In addition, the drawing display system 30 extracts paragraphs of claims or detailed descriptions related to reference numerals and displays them together with drawings on the screen.

Next, the database 40 includes a reading document DB 41 for storing the read patent document, and a drawing information DB 42 for storing reference numerals, positions of symbols, and descriptions of symbols of each drawing of the patent document, each It consists of a relation DB 43 and the like for storing reference numerals and relation information of each paragraph. However, the configuration of the database 40 is only a preferred embodiment, and in developing a specific device, it may be configured in a different structure according to the database construction theory in consideration of the ease and efficiency of access and search.

Next, the configuration of the drawing display system 30 according to an embodiment of the present invention will be described with reference to FIG. 2 .

As shown in FIG. 2 , the drawing display system 30 according to an embodiment of the present invention includes a screen configuration unit 31 that divides an output screen into a plurality of areas, and a drawing acquisition unit 32 that obtains drawings of patent documents. ), a reference number detection unit 33 for detecting reference numbers in the drawings, a reference number extraction unit 34 for extracting reference numbers for reference numbers, and a degree of relevance calculation for calculating the degree of relevance of each claim for each reference number. It is comprised by the part 36, and the claim etc. display part 37 which displays the claim etc. which have a degree of relevance on an output screen. In addition, a code description display unit 35 for displaying descriptions of symbols in the drawings, a drawing description display unit 38 for displaying descriptions of the drawings, or a claim storage unit 39 for storing claims having a degree of relevance, etc. may be included.

First, the screen configuration unit 31 divides the output screen into a plurality of areas. In each area, a window (window) displaying a drawing, a description of a reference number, a claim/detailed description, etc. is outputted, respectively.

As shown in FIG. 3, the output screen is divided into a claim display area (A), a claim list area (B), a drawing display area (C), a drawing list area (D), a code description area (E), and the like. .

Preferably, each region is configured to be resizable. For example, if the boundary line between the areas A and C of FIG. 3 is dragged left and right in a drag-in-drop form, the size of the area may be changed while the boundary line between the areas A and C moves left and right.

Also, preferably, each area is configured in the form of a normal window (window) displayed on the screen. However, the size of the window (window) in each area is adjusted to the size of the area. When the size of a window (window) in each area is changed, the size of the area is also changed, and accordingly, the size of the area between the neighboring areas of the corresponding area is adjusted.

3 and 4 , as the window of the region B is changed, the boundary line between the corresponding region B and the region A is changed, and the size of the region is changed accordingly. Conversely, when the size of the area is adjusted, the size of the window (window) is also adjusted accordingly.

In addition, each window (window) is provided so that all data can be viewed through scrolling by displaying a scroll bar when all data in the window cannot be displayed. A scroll bar is displayed in area A of FIG. 3 .

In addition, when a minimize command is input, only the title bar of each window (window) is displayed on the screen, and the content may not be displayed. At this time, since the size of the window is changed, the size of the area is also changed.

In addition, a plurality of pages may be configured in a window within one area, and in this case, one of the plurality of pages may be selected by a tab. In area A of FIG. 3 , it is composed of a claim page and a detailed description page, and according to the user's tab selection, one of the two pages may be selected and displayed on the screen.

On the other hand, in the example of FIG. 3, a claim display window (A), a claim list window (B), a drawing display window (C), a drawing list window (D), a code explanation window (E), etc. are respectively configured in each area . Each area and window all represent the same content, so the terms area and window (window) are used interchangeably.

Next, the drawing acquisition unit 32 obtains a drawing of the read patent document and displays it on the screen.

As described above, patent documents refer to published patent publications or registered patent publications, and include utility models as well as patents. In addition, both domestic and foreign patent publications are covered.

In particular, a patent document is divided into detailed items such as bibliography, detailed description, claims, and drawings, and the bibliography is composed of patent number, IPC classification, applicant, inventor, filing date, and the like.

Also, in a patent document, a drawing is composed of one or more multiple drawings (pictures). Here, the drawings refer to the entire figure, and each figure refers to an individual figure. However, for convenience of description, the drawings and drawings are used interchangeably below. That is, one individual figure is mixed as a figure.

On the other hand, the drawings acquired by the drawing acquisition unit 32 target one patent document. That is, with respect to one patent document previously searched for by the patent reading server 50 , the drawing of the corresponding patent document is to be read. Therefore, in the following, reference numerals and the like are also extracted from the corresponding patent document.

In addition, the drawing acquisition unit 32 displays one of the drawings (or drawings) of the corresponding patent document on the screen as a target. In particular, according to the user's selection, a drawing selected from among a plurality of drawings is displayed on the screen.

Also, a number of figures (or figures) are each assigned a figure number in the patent document. For example, a figure number is assigned, such as "Fig. 1 (Fig. 1)".

In addition, the drawing acquisition unit 32 detects the rotation direction of the drawing in each drawing, and returns to the original direction when the drawing is rotated. At this time, the rotation direction of the drawing is determined by the rotation direction of the reference numerals. In the example of FIG. 5A , when a reference numeral is rotated 90 degrees to the left, the drawing is rotated 90 degrees to the right, which is the opposite direction, to return to the original orientation as shown in FIG. 5B .

Meanwhile, preferably, it is possible to determine the direction of the reference numbers by detecting only 2-3 predetermined reference numbers without detecting all reference numbers on the drawing.

In addition, according to a predetermined rule, the drawing acquisition unit 32 deletes and excludes the rest (objects not related to the drawing object) while leaving only the object of each drawing and the reference number thereof. In the example of FIG. 5A, an object not directly related to the drawing object, such as "FIG.1", is deleted. Objects that are not related to drawing objects are determined in advance by rules.

That is, the drawing acquisition unit 32 obtains the drawing and performs pre-processing operations such as rotating the drawing or deleting unnecessary objects.

In this case, the drawing object refers to the object of the technical configuration to be expressed on the drawing. A reference number is displayed on each component of the drawing object, or a reference number is connected and displayed between each component of the drawing object by a connecting line. Accordingly, each drawing is composed of a drawing object, a reference number, and a connecting line.

Next, the reference number detection unit 33 detects reference numbers and their positions in the drawing. That is, a reference number is detected in the drawing, and the detected position is estimated as the position of the reference number.

Preferably, the reference number detection unit 33 detects the position of the reference number in the drawing based on a neural network method such as deep learning. More preferably, a RetinaNet model is used as a deep learning method.

That is, the reference number detection unit 33 uses an object recognition technology using a RetinaNet model specialized in drawings of the patent specification consisting of only black-and-white figures and numbers, unlike the object recognition technology for general image data processing, in the drawings. It is possible to detect the position of the symbol and obtain coordinate information of the reference symbol.

In addition, the reference number detection unit 33 generates a bounding box (bounding box) at the position of the detected reference number. The bounding box generated by the reference number detection unit 33 may have a rectangular border shape formed around the detected reference number. However, the bounding box may not be visually exposed. For example, the bounding box may be configured with a transparent color.

6 shows that reference numerals are detected in the drawing and a bounding box is displayed on the detected symbols.

In addition, preferably, the reference number detection unit 33 has an OCR (Optical Character Recognition) function specialized in the drawings of the patent specification, and uses this to recognize and extract the reference number located at the corresponding coordinate as a reference number in text format. . That is, the reference number detection unit 33 detects a reference number in a text format by recognizing a number or character by OCR in a bounding box generated in the reference number.

In addition, as another embodiment, the reference number detector 33 may extract a reference number in text format from reference numbers whose positions are detected based on a deep learning algorithm or a machine learning algorithm. Illustratively, the reference number detection unit 33 may use an OCR function such as ASTER to extract a reference number in text format from the reference number.

ASTER is an end-to-end neural network model composed of a rectification network and a recognition network, and it extracts text or numbers from within an image or bounding box. The reference number detection unit 33 learns ASTER in advance, inputs a bounding box, and extracts reference numbers in text format.

In the example of FIG. 6 above, reference numerals are extracted as 2, 4, 6, 8, 10, 12, 14, ..., and the like.

Next, the code description extracting unit 34 extracts code descriptions for reference numerals.

That is, the code description extracting unit 34 extracts a description (symbol description) of the reference numerals from the detailed description of the patent document with respect to the extracted reference numerals.

As an embodiment, the code description extracting unit 34 may extract a code description for a reference number from a sector in which "symbol description" of a patent document is performed, or may be input in advance by an administrator or the like.

As another embodiment, a reference number (or a reference number in text form) is detected within the detailed description of the patent document, and text or character strings positioned immediately before the detected reference number are extracted as the reference number.

In particular, by parsing a sentence including reference numerals, only a character string used as a subject or an object from the immediately preceding text is extracted. If there are a plurality of sentences including a reference number, the character string immediately preceding the corresponding reference number is extracted from all of the plurality of sentences, and the part of the character string that overlaps the most frequently among the extracted character strings is set as the description of the reference number. For example, "red patch 10" and "patch 10" are detected. In this case, if the number of duplicates of "patch" is the largest, the description of reference numeral "10" is set to "patch".

Also, preferably, the code description extracting unit 34 analyzes the character string of the code description, and extracts a similar character string of the code description. For example, within the detailed description of the patent document, "sidewall section" is also used as "sidewall". That is, a conventional similar string extraction method is applied.

7 shows the result of mapping the reference numerals to the reference numerals.

Next, the code description display unit 35 displays a description of the code for each code in the drawing on the corresponding drawing. Preferably, the blank space of the drawing is detected, and reference numerals are placed in the detected blank space of the drawing.

Preferably, the code description display unit 35 detects a blank area in the drawing image (image of each figure), but detects a blank area in which the boundary of the area consists only of horizontal and vertical sides.

Preferably, the length of the vertical side is set to be longer than a predetermined minimum length. In particular, the minimum length of the vertical side is set as the character height. In addition, the length of the width of the inner region is set to be longer than a predetermined minimum length. In this case, the minimum length of the region width is set to a predetermined width of the minimum number of characters.

For example, if the width of the region is set to a width of at least 4 characters, it is a length capable of writing at least 4 characters. That is, since the length of the vertical side is the height of the character, it becomes a space for writing one line of characters. Text spacing refers to the space between lines, and the letter height is the height of the corresponding letter. However, since the letter height means the height of the space occupied by the corresponding letter, it is regarded as the same as the line spacing.

Also, preferably, the code description display unit 35 detects a candidate blank area using a color in the drawing. That is, an area whose color is white (or background color) is detected as a blank area. As before, the detection is performed as a region composed of a vertical side and a horizontal side, but a region in which the width of the inner region and the length of the vertical side are equal to or greater than the minimum length is detected.

Fig. 8 illustrates the blank area detected within each figure (each figure) image. The gray area in the drawing is the blank area. As shown in FIG. 8 , a blank area may be detected even within an object of a drawing. That is, when the background color area inside the object has a certain size, it is detected as a blank area.

Meanwhile, the interval between the bounding box of the drawing object and the canvas box of the entire area may be adjusted. At this time, the size of the drawing object is determined in advance. Accordingly, the size of the canvas may be changed, such as increasing or decreasing. That is, the size of the canvas box is adjusted. Here, the bounding box of the object refers to a minimum rectangle including the object, and the canvas (or canvas box) refers to an area on the screen where the drawing is displayed.

In the example of Fig. 8, A represents the bounding box of the object, and B represents the canvas.

When the distance between the bounding box and the canvas box is small, the minimum length condition of the blank area may not be satisfied, and thus the blank area may be excluded.

In addition, the code description display unit 35 arranges code descriptions in the margins of the drawings.

That is, the code description display unit 35 sets an area (hereinafter referred to as a description area) in which the description of each reference number is to be arranged, and arranges each description area in a blank area so as not to overlap other description areas.

In this case, the size of the description area is determined by the size and number of characters of the code description. The font size consists of the height and width of the text. Font size refers to the space occupied by one character. In other words, it is distinguished from the size of the font and the size of the font (font).

In addition, the code description display unit 35 first arranges the description area of the corresponding code in the blank adjacent to the position of each reference number, and then arranges the description area of the reference number that is not arranged in the adjacent blank. Here, the adjacent blank position (or adjacent blank) refers to the adjacent positions of the upper, lower, left, and right at the position of the reference number (or the bounding box of the reference number).

That is, if the code description display unit 35 can arrange the description area of the reference number in the blank space (space within the blank area) adjacent to each reference number, the description area of the reference number is arranged first. do.

9 exemplifies the arrangement of the description area in the blank space adjacent to each reference number. In the example of FIG. 9 , only reference numerals “2”, “10”, “12”, “14”, “16”, and “18” may place drawing descriptions at adjacent positions. At this time, although there is a blank at a position adjacent to the reference numeral "4", the space is not large enough to describe the description "sidewall section" of the reference numeral "4" in the blank.

In addition, after arranging in the adjacent blank, for each non-arranged reference number, the reference description display unit 35 arranges the description area of the reference reference in the margin (position of the blank) closest to the position of the reference number.

10 exemplifies the arrangement of the description area in the nearest blank with respect to each reference number that is not arranged in the adjacent blank. In the example of Fig. 10, reference numerals "4", "6", "8", "20", "22", "24"

In addition, when the description area is disposed in a non-adjacent position, the code description display unit 35 connects and displays the description area and the corresponding reference number with a connecting line, or adds reference numerals to the description. When a reference number is added to the description of the reference number, the size of the description area is also changed as the reference number is added. Also, add both connectors and reference numbers, or optionally only one.

Next, the degree of relevance calculating unit 36 calculates the degree of relevance of each claim or paragraph with respect to each reference or each drawing.

First, the relevance calculating unit 36 divides the claims or detailed descriptions of the patent document into claim units or paragraph units (hereinafter, claims, etc. units), and calculates relevance for each unit. That is, the claims are composed of a plurality of claims, and each claim is divided into one unit. In addition, the detailed description consists of a plurality of paragraphs, and each paragraph is divided into one unit. The degree of relevance is calculated for each claim or each paragraph.

In this case, the paragraphs of the claims or detailed description will be referred to as “claims and the like”.

In addition, the degree of relevance calculating unit 36 calculates the degree of relevance of each claim and the like for each code explanation according to the frequency of appearance of the code description. The degree of relevance at this time will be referred to as "sign relevance".

Preferably, the higher the frequency of appearance of the code description, the higher the degree of code relevance is calculated. In particular, preferably, the degree of code relevance is set in proportion to the frequency of the code description. In addition, if the code description does not appear in the claim, etc., the degree of relevance of the code in the claim or the like is calculated as 0 or no.

On the other hand, when calculating the frequency of appearance of the code description, the frequency of occurrence is obtained including all of the code description or similar character strings of the code description. For example, if the similar string of "sidewall section" is "sidewall", the frequency of occurrence of "sidewall section" or "sidewall" is obtained. If similar character strings are duplicated, the frequency is not counted as duplicates. That is, if the "sidewall section" is counted once in the "sidewall section", the count is not duplicated in the "sidewall section".

The example in Fig. 11 shows the claims, and the reference numerals are "sidewall". In claims 1, 4, 5 and 9, "sidewall" appears.

In this case, the frequency and sign relevance of each claim for “sidewall” are shown in FIG. 12 . In this case, it is an example in which the degree of relevance is set as the frequency. 12 , it can be seen that claim 1 has the highest degree of relevance.

Next, the degree of relevance calculation unit 36 calculates the degree of relevance of each claim with respect to each drawing according to the number (number of types), or the number of code descriptions (hereinafter, the number of symbols) and the total frequency. to calculate The degree of relevance at this time will be referred to as "drawing relevance".

References to reference numerals in drawings refer to reference descriptions for reference numerals shown in the drawings. Since each drawing has a plurality of reference numerals, it has a plurality of reference numerals corresponding to each reference number. In the example of FIG. 10 , the corresponding figure has a number of reference numerals such as “tent”, “sidewall section”, “top portion”, and “clear trasition”.

The number of reference numerals (or number of reference symbols) refers to the number (number of types) of reference numerals appearing in the claims, etc. among the reference descriptions of the drawings. For example, even if "tent" appears 10 times in the claim, the number of code explanations becomes one.

The frequency of the code description refers to the total frequency of the code descriptions in the corresponding drawing. That is, it refers to the sum of the frequencies of each code explanation.

Preferably, the degree of drawing relevance is set in proportion to the number of symbols.

As another embodiment, the drawing relevance is set by weighted average or weighted sum of the number of symbols and the total frequency.

The example in Fig. 13 indicates the claims, and bold terms underlined indicate reference numerals. The number of symbols, the total frequency, and the drawing relevance of each claim with respect to the drawing are shown in FIG. 14 . In this case, the drawing relevance of FIG. 14 is a result of adding a weight of 0.7 to the number of symbols and a weight of 0.3 to the total frequency. 14 , it can be seen that claim 1 has the highest degree of relevance.

The example of FIG. 15 shows paragraphs [0024] and [0025] of the detailed description, and bold terms underlined indicate reference numerals. The number of symbols in each paragraph (paragraph in the detailed description), the total frequency, and the drawing relation are shown in FIG. 16 with respect to the drawing. In this case, the drawing relevance of FIG. 16 is a result of adding a weight of 0.7 to the number of symbols and a weight of 0.3 to the total frequency. In FIG. 16, it can be seen that paragraph [0024] of the detailed description has the highest degree of relevance.

Next, when a drawing or reference (or reference) is selected, the claim display unit 37 displays a paragraph (or a claim, etc.) of the claim or detailed description having a degree of relevance to the corresponding drawing or referenced description.

First, when a drawing is selected in the drawing list window (E), the claim display unit 37 displays a paragraph of a claim or detailed description in the claim display window (A) according to the drawing and the drawing relation. Preferably, the claim with the highest degree of relevance to the drawing is displayed first.

In addition, the claim display unit 37 determines the priority according to the highest order of drawing relevance for the corresponding drawing. That is, the higher the relevance, the higher the priority.

In addition, the claims, etc. display unit 37 displays a list of claims and the like on the claim list window B according to priority. In the example of FIG. 14 , the priority of the drawing relevance is claims 1, 4, 5, and the rest of the claims. Accordingly, the claims are listed first by this priority.

Preferably, the claims, etc. display unit 37 highlights and displays the referenced description in the paragraph of the claim or detailed description in the claim, etc. display window (A).

On the other hand, preferably, the claims, etc. display unit 37 highlights and displays the description of the symbols in the drawing display window (C) or the symbol explanation window (E), etc. in synchronization with the description of the symbols displayed by highlighting them in the display window (A). .

In addition, more preferably, the claims, etc. display unit 37 is displayed by highlighting in different colors if the descriptions of the symbols are different from each other. In particular, if descriptions of symbols displayed on the claim display window (A), the drawing display window (C), or the symbol explanation window (E) are identical to each other, they are displayed in the same color.

Next, the claim display unit 37, when a symbol description or a symbol is selected in the drawing display window (C) or the symbol explanation window (E), according to the degree of relevance of the symbol (or description of the symbol of the symbol), claims or Paragraphs of detailed description are displayed in the claim display window (A). Preferably, the claim with the highest degree of sign relevance is indicated.

In addition, the claim display unit 37 determines the priority according to the highest order of degree of relevance of the code to the corresponding code description, and displays the list of claims, etc. on the claim list window (B). In the example of FIG. 12 , the priorities of the drawing relevance are 1, 4, 5, and 9. Accordingly, the claims are listed first by this priority.

FIG. 17 shows an example in which claims and the like for the code description of “sidewall” are indicated.

Preferably, as shown in Fig. 17, the claims, etc. display unit 37 highlights and displays the referenced description in the paragraph of the claim or detailed description in the claim, etc. display window (A).

On the other hand, preferably, the claims, etc. display unit 37 highlights and displays the description of the symbols in the drawing display window (C) or the symbol explanation window (E), etc. in synchronization with the description of the symbols displayed by highlighting them in the display window (A). .

On the other hand, as another embodiment, the claim display unit 37 displays the hierarchical structure of claims in the claim list window (B). The hierarchical structure of claims indicates the structure by reference and citation relationship. That is, the relationship between the two claims indicates the relationship between citation and citation. The cited claim is the parent claim of the cited claim, and the cited claim is a sub-claim of the cited claim.

The hierarchical structure of claims is displayed in the claim list window (B) of FIG. 17 .

Preferably, as shown in FIG. 18 , in the hierarchy of claims, claims having a degree of relevance to the reference description (claims having a degree of relevance greater than 0) are highlighted and displayed, or only claims having a degree of relevance are displayed.

Meanwhile, more preferably, the highlight color may be displayed differently in proportion to the size of the degree of relevance. As an example, as the size of the degree of relevance increases, the density (saturation) of the highlight color is displayed differently. That is, the greater the degree of relevance, the darker the color density or saturation is displayed. As another example, a series of colors such as red-orange-yellow-green-blue-indigo-purple may be set, and the corresponding colors may be assigned and displayed according to the size of the degree of relevance.

In addition, preferably, the claim display unit 37 determines the priority according to the order of the degree of relevance of the code to the description of the code, and highlights and displays the claim with the degree of relevance or displays the claim with the degree of relevance, When a subclaimed claim (quoted claim) has a high priority, it is characterized in that the related subclaim and the related upper claim (quoted claim) are displayed together in the claim display window (A). More preferably, all claims that are higher in the citation are indicated together.

In the example of FIG. 18 , when claim 4 has the highest priority (or highest) and the content of the claim is displayed on the claim display window (A), the content of claim 1, which is the cited claim of claim 4, is also displayed. In addition, when claim 5 has a high priority, both claims 4 and 1, which are the upper claims of claim 5, may be indicated.
