Patent number: 8229908Abstract: One embodiment of the present invention provides a system that facilitates dividing financial data to facilitate simultaneous modifications by multiple users. During operation, the system receives division-criteria, which facilitates dividing financial-data into a first subset and a second subset. Next, the system creates a copy of the financial-data which includes the division-criteria. The system then allows a first user to modify the first subset of the financial-data. The system also sends the copy of the financial-data to a second user, thereby enabling the second user to modify the second subset of the financial-data in the copy of the financial-data to create a change file. Subsequently, the system receives the change file from the second user, wherein the change file comprises modifications to the financial-data. Finally, the system merges the change file into the financial-data.Type: GrantFiled: April 30, 2007Date of Patent: July 24, 2012Assignee: Intuit Inc.Inventors: David B. DeGraaff, Andrew D. Holmes, Puja Ramani, Teresa L. Roberts, Harold E. Schoolcraft

Method and apparatus for facilitating simultaneous modifications to financial-data by multiple users
Patent number: 7653613Abstract: One embodiment of the present invention provides a system that facilitates simultaneous modifications to financial-data by a first user and a second user. During operation, the system creates a copy of a financial-data file. The system then allows the first user to modify the financial-data file. The system also sends the copy of the financial-data file to the second user, thereby enabling the second user to modify the financial-data file to create a change file. Next, the system receives the change file from the second user, wherein the change file includes modifications to financial-data within the financial-data file. Finally, the system merges the change file into the financial-data file.Type: GrantFiled: January 31, 2007Date of Patent: January 26, 2010Assignee: Intuit Inc.Inventors: David B. DeGraaff, Andrew D.

Publication number: 20080270310Abstract: Embodiments of a system that provides access to at least a portion of a software product are described. During operation, this system receives purchase information from a first location, where the purchase information includes information about purchased software features to which a user purchased access and where the purchased software features are provided by a first subset of modules in the software product. Next, the system receives an access request from a second location from which the software product can be accessed, where the access request includes an identifier provided to the user when the user purchased access to the purchased software features. Next, the system provides configuration instructions to the second location, where the configuration instructions dynamically enable the first subset of the modules.Type: ApplicationFiled: July 27, 2007Publication date: October 30, 2008Applicant: INTUIT INC.Inventors: David B.

Publication number: 20020059289Abstract: The methods and systems of the invention involve the generation and use of a cross-linked keyphrase ontology database. The database is generated by defining at least one keyphrase, representing the keyphrase by a keyphrase node in an ontology, cross-linking the keyphrase node to a second keyphrase node, and then repeating the preceding steps for each keyphrase defined. A retrievable object can be indexed in a cross-linked keyphrase ontology database by representing the retrievable object by an object node in an ontology and then cross-linking the object node to a keyphrase node, where the keyphrase node represents a keyphrase in a second ontology and the keyphrase is related to the retrievable object. The cross-linked keyphrase ontology database can be searched by parsing a natural language statement into a structured representation and searching the cross-linked keyphrase ontology database. The cross-linked ontology database can be used for disambiguating syntactically ambiguous natural language statements.Type: ApplicationFiled: July 6, 2001Publication date: May 16, 2002Inventors: Brant Gary Wenegrat, David B.
