Referring to FIG. 2, the claim visualization apparatus 110 may include a receiver 210, a claim comparison unit 220, a keyword analyzer 230, a form providing unit 240, and a web page providing unit 250.

The receiver 210 receives a visualization request signal from the user terminal 130.

According to the visualization request signal, the claim comparison unit 220 matches each claim of the published patent publication and the registered patent publication corresponding to the specific patent and arranges them in a specific region.

For example, the claim comparison unit 220 is arranged in a specific area so that the claims having the same number of the published patent publication and the registered patent publication are located side by side. At this time, if there is a claim deleted in the correction process of the claims of the registered patent publication, the claim comparison unit 220 may place a blank in the area corresponding to the deleted claim.

In addition, the claim comparison unit 220 may calculate the number of the entire claims, the independent claims and the dependent claims, and the number of the single reference and the multi-referenced claims in the Published Patent Publication and the Registered Patent Publication, and arrange them in a specific region.

The claim comparison unit 220 transmits the claims arranged in the specific area to the keyword analysis unit 230 and the format providing unit 240. Thereafter, the claim comparison unit 220 receives the edited claims from the keyword analysis unit 230 and the format providing unit 240 and arranges the edited claims in a specific area.

The claim comparison unit 220 generates setting information about the claim, the number of claims, and the arrangement of the claims for comparing the claims, and transmits the setting information to the webpage providing unit 250.

The keyword analysis unit 230 extracts the morphemes included in the claims arranged by the claim comparison unit 220 by using a morpheme analysis device (not shown), and changes the text attributes corresponding to the corresponding morphemes included in the previous claims. . The text attribute is setting information on the font and color of the text. For example, the keyword analyzer 230 may change the text attribute of a specific morpheme so that the text corresponding to the morpheme becomes red. The keyword analysis unit 230 is connected to an external morpheme analysis device (not shown) to transmit a specific claim to the morpheme analysis device, and receives a morpheme extracted from the specific claim by the morpheme analysis device (not shown). A morpheme analysis apparatus (not shown) is a natural language processing apparatus for extracting meaning from a natural language string, and is one of known devices capable of extracting a morpheme by receiving a sentence written in a natural language. Of course, it will be apparent to those skilled in the art that the keyword analysis unit 230 may include a morphological analysis device (not shown) therein.

The format providing unit 240 divides the contents of the claims arranged in the claim comparison unit 220 into predicates, transitions, and features, and edits the claims to indent the character strings of the features. In addition, the form providing unit 240 edits a claim to form a paragraph for each component when one or more of the preamble and the feature include a plurality of components such as a step and a functional unit. At this time, the premise is a section in which the name, definition, scope of the invention and the prior art in the technical field related to the invention, etc., which are claimed in the claims. A feature is a phrase in which the technical features of the invention to be protected are described. The transition part is a phrase that describes the subject matter of the claims.

The form providing unit 240 may include a parser capable of storing the patterns of the predicates, the transition parts, and the features and the patterns of the components in advance and parse the claims using the same, or may be connected to an external parser. For example, the parser is pre-stored as a pattern ending with a predicate in the claims, and may parse the content before the phrase as a preamble.

An edited form of the format providing unit 240 will be described in detail later with reference to FIG. 5.

The webpage providing unit 250 receives the setting information on the claim from the claim comparison unit 220 and generates a webpage according to the setting information. Subsequently, the webpage providing unit 250 transmits the generated webpage to the user terminal 130 requesting time information.

The hierarchical analysis unit 225 determines the dependency relationship between the claims, and generates a relationship diagram indicating the determined dependency relationship. For example, the hierarchical analysis unit 225 determines whether the claim is a dependent claim based on the presence or absence of a predicate indicating a reference as in “claim 1” included in each claim. Subsequently, the hierarchical analysis unit 225 extracts a number from the preamble of the dependent term to grasp the claims referred to by the dependent term. The hierarchical analysis unit 225 is any one of 'paragraph 1', 'paragraph 1', 'paragraph 1 or 2', 'paragraph 1, 2 and 3'. A plurality of premise patterns indicating a reference such as' is stored in advance, and parsing may be performed to extract the premise part using the stored pattern.

In addition, the hierarchical analyzer 225 may set the independent term as the highest node, generate a relational diagram having the dependent term corresponding to the independent term as a lower node, and arrange the generated term in the specific region.

When the user receives a signal for an input for selecting a specific node of the relationship diagram, the hierarchical analyzer 225 may arrange the content of a claim corresponding to the corresponding node in a specific region.

Details of the hierarchical analysis unit 225 generating the relationship structure and arranging it in a specific region will be described later with reference to FIG. 6.

When the hierarchical analysis unit 225 receives an input of a user for selecting a node on the relationship diagram, the hierarchical analyzer 225 may arrange a claim corresponding to a node selected in a specific region and a claim referred to a selected node. In this case, the arranged claims may be edited by the keyword analyzing unit 230 and the format providing unit 240 by the above-described process with reference to FIG. 2. That is, the hierarchical analysis unit 225 transmits a claim corresponding to the selected node and a claim referred to by the selected node to the keyword analyzing unit 230 and the form providing unit 240 to request editing, and then edited. Claims can be received and placed in specific areas.

The hierarchical analyzer 225 may include a parser capable of parsing the preamble of the claim or may be connected to an external parser.

Referring to FIG. 5, the claim comparison unit 220 generates a tree (hereinafter referred to as a claim tree) according to the dependency of each claim of the published patent publication and the registered patent publication corresponding to the user's selected patent. At this time, the claim comparison unit 220 may include a node representing the claim 410 deleted or abandoned in the claims of the registered patent in the tree.

In addition, the claim comparison unit 220 arranges the patent name, the progress state, the total number of claims, the number of independent claims, the number of dependent claims, and the claim tree of the published and published patent publications to be compared side by side.

The claim comparison unit 220 arranges the claims of the specific node and the node corresponding to the specific node in parallel with the claim content comparison column 420 according to a signal corresponding to the selection of the specific node of the user.

In this case, the claim comparison unit 220 may perform the same predicate parsing function for analyzing the claim dependency relationship of the hierarchy analyzer 225.

FIG. 6A illustrates a web page including hierarchical information according to an embodiment of the present invention, and FIG. 6B illustrates a web including hierarchical information when a block of FIG. 6A is clicked according to an embodiment of the present invention. The figure shows a page.

Referring to FIG. 6A, the hierarchical analysis unit 225 grasps a dependency relationship according to a preamble of each claim, and generates a relationship diagram showing a node corresponding to each claim for each hierarchy according to the dependency relationship.

For example, the hierarchical analyzer 225 arranges a button representing the independent term at the top node, and arranges a button representing the claim referring to the independent term in the next layer (1 Depth). That is, the hierarchy analysis unit 225 is arranged to include a claim that refers to a claim corresponding to a higher node in the next hierarchy. In this case, the hierarchical analysis unit 225 may group the claims that refer to the same claim as one block. In addition, the hierarchical analysis unit 225 may indicate the dependency relationship between the claims with an arrow.

The hierarchical analyzer 225 may indicate a dependency relationship with an arrow corresponding to a single reference or multiple references. For example, the hierarchical analyzer 225 may indicate a single reference as a bold arrow and multiple references as a general arrow. Of course, the hierarchical analyzer 225 may distinguish the arrow classification corresponding to a single reference or multiple references by the color, shape, etc. of the arrow in addition to the thickness.

In addition, the hierarchical analyzer 225 arranges all terms buttons 530 and 540 corresponding to each independent and dependent term group. The hierarchical analyzer 225 may arrange the contents of all the dependent terms of the dependent term group corresponding to the full term buttons in the selected claim content column 550 according to the manipulation of the full term buttons 530 and 540. In addition, the layer analysis unit 225 may arrange all the dependent terms of the hierarchy below 1 Depth referring to the independent terms in the selected claim content field 550 according to the operation of the entire term button 530 corresponding to the independent terms.

When the hierarchical analysis unit 225 receives a signal for selecting a specific node included in the relationship diagram, the hierarchical analysis unit 225 places the corresponding claim in the selected claim content field 550, and the claim content field 560 referenced by the claim selected by the claim referred to by the claim. ) Can be placed. The hierarchical analysis unit 225 transmits hierarchical information including the relationship diagram, the selected claim content field 550, and setting information about the claim content 560 referred to by the selected claim, to the webpage providing unit 250. That is, the claim visualization apparatus 110 may receive a signal according to an input for selecting a specific node from the user terminal 130 and arrange the content of the claim corresponding to the received signal in the selected claim content field 550. have.

The user terminal 130 may receive a user input for selecting a block on the relationship diagram, generate a signal corresponding thereto, and transmit the generated signal to the claim visualization apparatus 110. In this case, the input for selecting a block may be an input for selecting all the terms buttons 530 and 540 or a node of each claim or an input for clicking inside the boundary of the block. When the hierarchical analyzer 225 receives a signal corresponding to a block selection, the hierarchical analyzer 225 may change a visual effect of an arrow indicating a reference of a node included in the block. For example, when the hierarchical analyzer 225 receives a signal corresponding to the selection of the user's block 570, the hierarchical analyzer 225 may change the color of the arrow indicating the reference of the node included in the block as shown in 580 of FIG. 6B.

The keyword analyzing unit 230 extracts 'polyisocyanate' in claim 5 selected by the user, and uses the extracted keyword color as the color of the plain text (black in this embodiment) and a color other than the color of other keywords (this embodiment). In this example, the text attribute of the extracted keyword is set to set to blue. Of course, the keyword analysis unit 230 may change the text property to change the font instead of the text color of the extracted keyword.

Therefore, the keyword analyzing unit 230 sets the 'polyisocyanate' included in claim 5 and claim 1 which are the claims selected in FIG. 4 to blue. The keyword analyzing unit 230 transmits keyword information including the text property setting content for each keyword to the webpage providing unit 250.

Although the above-described hierarchical analysis unit 225 has been described as changing the visual effect of the arrow indicating a reference when receiving a signal according to the user input, the web page providing unit 250 changes the visual effect of the arrow according to the user input. A web page set in advance may be generated and provided to the user terminal 130.
