Re: Samsung Electronics Co., Ltd, et al. v. ON Semiconductor Corp., et al.,
Civil Action No. 06-720 (JJF)
ON Semiconductor Corp., et al. v. Samsung Electronics Co., Ltd., et al.,
Civil Action No. 07-449 (JJF)
Dear Judge Faman:
I write on behalf of Plaintiff Samsung Electronics Co., Ltd., in response to Defendant ON
Semiconductor Corp.’s April 25, 2008, letter requesting that the Court schedule a technology
tutorial in advance of the May 21, 2008, Markman hearing. Samsung believes that it would be
more efficient to provide a brief overview of the technology relating to each of the five patents-
in-suit at the Markman hearing itself, so that the focus remains centered on the patents and
disputes at issue. That approach will also help ensure that the claim construction analysis does
not improperly stray from the context in which the disputed terms are used in the written 1*
description and prosecution history. Of course, if the Court believes that a more generic
technology tutorial would be helpful, Samsung will provide whatever information the Court
deems appropriate. 1
l

Respectfully submitted,
Andrew A. Lundgren 6* 429)
