聯詠與Honeywell和解

Honeywell於2007年3月控告聯詠以及其他10家公司,並主張聯詠藉由販賣驅動IC給面板製造廠商,涉及惡意侵害該公司的US 5,041,823 號專利。
美國東德州地方法院於2009.1.界定了對聯詠有利的專利範圍,同時,聯詠亦提出確定不侵權的簡易判決(summary judgment)請求,主張並無任何間接或直接侵權。
2009.6.8.美國東德州地方法院法院根據至少兩個不侵權理由,正式判決聯詠勝訴。
2009.7.13.雙方正式達成和解,撤回所有告訴。

聯詠的訴訟策略
聯詠提出US5,041,823 號專利的再審查,而美國專利商標局於再審查程序中核駁了該專利的所有權利項。Honeywell若要繼續主張US5,041,823 號專利的權利,不但要面對地方法院的不利判決,還要克服美國專利商標局的核駁決定。

US5,041,823
Title:Flicker-free liquid crystal display driver system
Filing Date:1988.12.29.
Issue Date:1991.8.20.
Abstract:
A flicker-free liquid crystal display driver system driving two groups of pixels with alternating polarities. The spatial differentiation of the two groups, which may be accomplished in terms of even and odd rows or columns, is small so as to diminish detection by a human eye of the flicker in the display. The driver system incorporates a level shifter, switches, drivers, a driver switch control, a holding means and a storage means. Input signals to the system include that of intensity data, a clock and frames. The configuration of the driver system may be of a single-edge or redundant drive. The system may be digital or analog.
