Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 136 words
A circuit having a logic path that serves as a sequence of instructions for retrieving documents from a database, the sequence of instructions comprising the steps of: creating a plurality of document images from a plurality of documents; recognizing characters in said document images to produce a document text; determining regions of the document images that correspond to words of the document text; correlating said regions with said text; searching said text in response to a query; retrieving document text in response to said search; displaying the corresponding document image; receiving an input that selects a portion of the document image; determining a selected text from the document text that corresponds to the portion of the document image; generating an updated query from said selected text; and searching said text in response to said updated query.
Claim 2
Dependent Claim 136 words
A circuit having a logic path that serves as a sequence of instructions for retrieving documents from a database, the sequence of instructions comprising the steps of: creating a plurality of document images from a plurality of documents; recognizing characters in said document images to produce a document text; determining regions of the document images that correspond to words of the document text; correlating said regions with said text; searching said text in response to a query; retrieving document text in response to said search; displaying the corresponding document image; receiving an input that selects a portion of the document image; determining a selected text from the document text that corresponds to the portion of the document image; generating an updated query from said selected text; and searching said text in response to said updated query.
Claim 3
Dependent Claim 86 words
The circuit of claim 1 wherein: the step of receiving an input that selects a portion of the document image includes the step of receiving a first co-ordinate and second co-ordinate in the document image; and the step of determining a selected text from the document text that corresponds to the portion of the document image includes the step of determining a first offset into the document text and a second offset into the document text based on the first co-ordinate and the second coordinate, respectively.
Claim 4
Dependent Claim 128 words
An input processing apparatus for a search engine, comprising: an OCR device for recognizing characters in a document image to produce a document text; a computer for reading said document text; a circuit logic path serving as a sequence of instructions that determine regions of the document image that correspond to words of the document text; a display unit for displaying the document image; a cursor control mechanism for receiving an input that selects a portion of the document image; a circuit logic path serving as a sequence of instructions that determine a selected text from the document text that corresponds to the portion of the document image; and a circuit logic path serving as a sequence of instructions that update a query based on said selected text.
Claim 5
Dependent Claim 128 words
An input processing apparatus for a search engine, comprising: an OCR device for recognizing characters in a document image to produce a document text; a computer for reading said document text; a circuit logic path serving as a sequence of instructions that determine regions of the document image that correspond to words of the document text; a display unit for displaying the document image; a cursor control mechanism for receiving an input that selects a portion of the document image; a circuit logic path serving as a sequence of instructions that determine a selected text from the document text that corresponds to the portion of the document image; and a circuit logic path serving as a sequence of instructions that update a query based on said selected text.
Claim 6
Dependent Claim 67 words
The apparatus of claim 3 , wherein: the cursor control mechanism is configured to receive a first co-ordinate and a second coordinate in the document image; and said circuit logic path that determines the selected text includes circuit logic path that determines a first offset into the document text and a second offset into the document text based on the first co-ordinate and the second co-ordinate, respectively.
Claim 7
Dependent Claim 140 words
A circuit and computer readable media that combine to serve as and create a sequence of instructions for retrieving documents from a database, the sequence of instructions comprising the steps of: creating a plurality of document images from a plurality of documents; recognizing characters in said document images to produce a document text; determining regions of the document images that correspond to words of the document text; correlating said regions with said text; searching said text in response to a query; retrieving document text in response to said search; displaying the corresponding document image; receiving an input that selects a portion of the document image; determining a selected text from the document text that corresponds to the portion of the document image; generating an updated query from said selected text; and searching said text in response to said updated query.
Claim 8
Dependent Claim 140 words
A circuit and computer readable media that combine to serve as and create a sequence of instructions for retrieving documents from a database, the sequence of instructions comprising the steps of: creating a plurality of document images from a plurality of documents; recognizing characters in said document images to produce a document text; determining regions of the document images that correspond to words of the document text; correlating said regions with said text; searching said text in response to a query; retrieving document text in response to said search; displaying the corresponding document image; receiving an input that selects a portion of the document image; determining a selected text from the document text that corresponds to the portion of the document image; generating an updated query from said selected text; and searching said text in response to said updated query.
Claim 9
Dependent Claim 90 words
The circuit and computer readable media of claim 1 wherein: the step of receiving an input that selects a portion of the document image includes the step of receiving a first co-ordinate and second co-ordinate in the document image; and the step of determining a selected text from the document text that corresponds to the portion of the document image includes the step of determining a first offset into the document text and a second offset into the document text based on the first co-ordinate and the second coordinate, respectively.
