億光與日亞化的訴訟

跟這種擁有基礎專利的公司打侵權訴訟應該要很厲害，台灣的億光也算是很重視專利佈局的企業，以台灣案的專利量來看，億光新式樣119件、新型96件、發明226件（排除公告與公開專利重複計算的數目）（資料取得5.11.2012）。就億光發明、新型與新式樣的佈局來看，這幾年億光以終端產品為主要佈局，因此新式樣大增，億光也在幾年前終止新型的佈局，而完全著重發明案的佈局，顯見其專利佈局除了終端照明產品的佈局外，也積極朝著重攻防的發明專利佈局。

ZENARO公司為億光的持股公司，其產品辦公室照明（型號：OL-Deluxe/QL2/P44/LF/D50/SR/ M/CE/ZN）使用螢光燈（型號：SL-Cobra/T5 048DC/C/P10/LF/D50/ZN）


日亞化學工業（Nichia）控告上述產品侵害其歐洲專利EP936682（LIGHT EMITTING DEVICE AND DISPLAY DEVICE）

EP936682揭露一種發光二極體與顯示裝置，
各獨立範圍可以參考一下：

其中揭示一種發光裝置，包括一個發光元件與一螢光體，螢光體吸收一部分發光元件產生的光，並激發出不同於吸收光波長的光；其中發光元件包括有氮化物的半導體，螢光體包括有由鈰致活的紅寶石螢光體，其中具有Y, Lu, Se, La, Gd, Sm中至少之一的元素，與由Al, Ga, In中選擇至少之一的元素。
1. A light emitting device, comprising:
a light emitting component and
a phosphor capable of absorbing a part of light emitted by the light emitting component and emitting light of wavelength different from that of the absorbed light;
wherein said light emitting component comprises a nitride compound semiconductor and said phosphor contains a garnet fluorescent material comprising at least one element selected from the group consisting of Y, Lu, Se, La, Gd and Sm, and at least one element selected from the group consisting of Al, Ga and In, and being activated with cerium.


另有獨立範圍界定了LED燈的驅動電路與發光二極體：

以陣列型式排列LED的顯示裝置與根據顯示數據的驅動電路。（這應該不是主張侵權的範圍）
13. An LED display device comprises the light emitting devices according to one of claims 1 to 10 arranged in a matrix and a drive circuit which drives the LED display device according to display data which is input thereto.

一種發光二極體，包括：具有帽與引線的安裝引線、裝設於帽上的LED晶片，其中電極電連接到引線上、填充於帽而覆蓋LED晶片的透明塗布材料，以及發光二極體，其中LED晶片內容即如上述Claim 1所述。
14. A light emitting diode comprising:
a mount lead having a cup and a lead;
an LED chip mounted in the cup of the mount lead with one of electrodes being electrically connected to the mount lead;
a transparent coating material filling the cup to cover the LED chip; and
a light emitting diode having a molding material which covers the LED chip covered with the coating material including the cup of the mount lead, the inner lead and another electrode of the LED chip, wherein
the LED chip is a nitride compound semiconductor and the coating material contains at least one element selected from the group consisting of Y, Lu, Sc, La, Gd and Sm, at least one element selected from the group consisting of Al, Ga and In and a phosphor made of garnet fluorescent material activated with cerium.
