Panavision Imaging, LLC v. Omnivision Technologies

February 3, 2012

PANAVISION IMAGING, LLC, CANON U.S.A., INC.'S
PLAINTIFF,
v.
OMNIVISION TECHNOLOGIES, INC. ET AL., DEFENDANTS.



The opinion of the court was delivered by: Hon. Mariana R. Pfaelzer United States District Judge

ORDER GRANTING MOTION FOR SUMMARY JUDGMENT OF NONINFRINGEMENT

I.INTRODUCTION

Defendant Canon U.S.A., Inc. ("Canon"), moves for summary judgment that all of its accused products do not infringe Plaintiff Panavision Imaging, LLC's ("Panavision") U.S. Patent No. 6,818,877 ("the '877 patent") (filed May 17, 2002). Canon's motion presents two closely related issues: (1) What is the claim scope of the '877 patent? (2) Do Canon's accused products meet the limitations of the '877 patent? The first issue is a legal question of claim construction. The second is a factual question for summary judgment. Because the Court finds that Canon's accused products do not meet the claim scope of the '877 patent, the Court grants Canon's motion.

II.LEGAL STANDARDS

The legal standard for a moving party to prevail on a motion for summary judgment is well established. "If the movant shows that there is no genuine dispute as to any material fact and that the movant is entitled to judgment as a matter of law," summary judgment is proper. Fed. R. Civ. P. 56 (a). A court must view the evidence in the light most favorable to the non-moving party and draw all justifiable inferences in its favor. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255 (1986).

III.BACKGROUND

The '877 patent discloses a "video bus for an array of pixel amplifiers . . . designed for a minimum quiescent current draw." The '877 Patent, at Abstract. The disclosed electrical circuit includes a "pixel amplifier (or column amplifier)" with "high impedance pull-ups and low impedance pull-downs to conserve over-all power dissipation." Id. A pull-up amplifier is connected to the bus.*fn1 Id. at 3:13--16. The pull-up amplifier's role is to reset the bus to a reference voltage at the times when circuit disconnects the column amplifiers from the bus. Id. at 2:56--60. Claim 1 is as follows:

1. Analog bus for a solid state video imager, comprising

a) one or more conductive channels;

b) a plurality of column output amplifiers, each connected with a selected pixel of its associated column, and having a low-impedance amplifier device;

c) respective switching means for selectively connecting outputs of the column amplifiers to said one or more conductive channels; and

d) a pre-charging high-impedance pull-up amplifier coupled to said one or more conductive channels for periodically charging up the one or more conductive channels between connections of said switching means.

The '877 Patent, at 3:5--17.

The patent's four key components work together. They are the conductive channel, the array of column amplifiers, switches to connect each of the column amplifiers to the conductive channel, and a pull-up amplifier for charging the conductive channel. According to the sole figure in the '877 patent, the conductive channel forms the central nexus of the device. The '877 Patent, at fig.1. The column amplifiers (with the associated video inputs) ...
