Abstract: A computerized system and method for generating patent data summary reports for a target entity identified by the user. The information system contains a database containing patent document records. After a user selects the target entity, the system issues a query to the database to identify all entities having a association with patent documents associated with the specified target entity. For example, the user may wish to receive a report on all the clients of a specific attorney. The system would search the database to locate all assignees of all patents prosecuted by that attorney and return a ranked list of such assignees to the user. Optionally, the system may generate a graphical representation of the information in the report and provide it to the user. The report provided to the user may be interactive in a sense that various items of information within the report may be connected by way of links to additional reports with more specific information on those particular items.

Abstract: A system that efficiently performs a CMOD operation in solving a system of equations involving a sparse coefficient matrix by identifying supernodes in the sparse matrix. Each supernode comprises a set of contiguous columns having a substantially similar pattern of non-zero elements. The system performs a CMOD operation on each supernode, by determining a structure for the supernode, and computing a function of the structure. The system uses a one-dimensional trapezoidal representation for the supernode during the CMOD operation, if the result of the function is lower than a threshold value, and otherwise uses a two-dimensional rectangular representation for the supernode. The function of the structure of the supernode is a function of a number of computational operations involved in computing a lower-triangular sub-block portion of the supernode and a number of computational operations involved in computing a rectangular sub-block portion of the supernode.
