  • Publication number: 20130166460
    Abstract: The present subject matter discloses systems and methods for managing patents in an enterprise. In one implementation, the method for patent management in the enterprise comprises defining an enterprise patent service set of a plurality of enterprise patent services, wherein the enterprise patent services set comprises portfolio service, process service, and program service, and defining an enterprise patent capability set of a plurality of enterprise patent capabilities, for delivering each of the enterprise patent services in the enterprise patent service set, wherein the enterprise patent capability set comprises promote, profit and protect. The method further comprises mapping each of the enterprise patent services in the enterprise patent service set with each of the enterprise patent capabilities in the enterprise patent capability set so as to generate an objective for each pair of enterprise patent service and enterprise patent capability.

  • Patent number: 7900174
    Abstract: A method and a system for characterizing an integrated circuit (IC) design are disclosed. The method includes receiving a description of leaf cells used in the IC design. The IC design is described in a high-level language by using the description of the leaf cells. The description of the IC design includes specifying placement of the leaf cells and specifying connectivity between them. Further, the method includes extracting a circuit netlist file based on the physical layout of the IC design. The instructions are defined in the high-level language to perform simulations on the extracted circuit netlist file. These simulations are performed on the circuit netlist file to determine the values of the design parameters. Furthermore, the method includes providing the values of the design parameters of the IC design in a pre-defined output format based on the simulations.

  • Patent number: 7542930
    Abstract: A scenario manager allows users to define document-based choreography and simulate the behavior of a trading partner in a computer system. Rules are utilized to orchestrate the transaction sequence to test the functionalities and performances of the system as a whole and trading partners that participate in a scenario. Each scenario is defined with one or more steps, each of the steps having a condition and/or an action, wherein the condition defines prerequisites for the step to be executed and the action defines what happens if the step is executed. All the steps that have no conditions are executed first, resulting in one or more responses being received from trading partners. Then all steps having conditions that are satisfied in light of any responses received are performed. This is then repeated until no more conditions are satisfied or there are no steps left to perform.
