Appeal No. 2005-2512
Reexamination Control No. 90/006,431
respectively, of the ‘952 patent. Had Ho intended to credit himself and Tuan with the
invention of ChipViewer per se, his paragraph 4 and 5 testimony should have asserted
that to the extent the RailMill documents describe RailMill and ChipViewer, they
describe an embodiment of their invention. Appellant is therefore incorrect to
characterize Ho’s testimony as establishing that Ho and Tuan invented “both
ChipViewer and ChipViewer integrated with RailMill,” R.Br. 14, and to assert that ”the
inventors herein are responsible for ChipViewer.” Br. 12. Moreover, as explained
below, that position appears be contrary to other evidence of record, including the
Arcadia Manual.
We will first, however, consider Ho’s testimony vis-á-vis the RailMill documents.
We begin by noting it is evident from the details given in the RailMill documents that
they are directed to the same power net simulation engine, associated transistor
network simulation engine, and use of ChipViewer to display the output of the power net
simulation engine that are disclosed and claimed the ‘952 patent. For example, the
RailMill Tutorial discusses the steps of (a) converting the Dracula database to Arcadia
(see p. S0059876), (b) performing RC extraction (S00569880), (c) creating a power net
netlist (S0059881), and (d) running the RailMill simulations to obtain images
representing electromigration, voltage drop, and power grids (S0059882-85).21 Also,
the “ShowSim” software discussed at pages S0059883-85 of the RailMill Tutorial
21 The RailMill Tutorial also explains that all of these functions are controlled
using ChipViewer.
