這樣有侵犯專利嗎? - 專利

請叫各位前輩:

如果有一篇美國專利是這樣 他的權利項只有宣稱 light emitting diode
但是他在說明中指出這個LED 可以是infrared 那如果我們也使用紅外光的
光源 是不是靜觸碰它的專利 如果是要如何避免? 如下文所示:

What is claimed is:

1. A modulated optical mouse for a personal computer, the optical
mouse comprising:

a body having a predetermined space defined inside the body and
having at least one lead securely provided inside the space and
feet each electrically connected to one of the feet;

at least one light emitting diode mounted inside the space to
^^^^^^^^^^^^^^^^^^^^
electrically connect with the lead, the light emitting diode being
at a bottom of the body; and

at least one sensor received in the space to electrically connect
with the lead and to correspond to the reflective light from
reflective surface (table surface) of light emitting diode.


DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0024] The LED 3 is mounted inside the space 21 to electrically
connect with the lead 22. The LED 3 is at the bottom of the body 2
and is able to emit visible light, infrared and the like.
