請教方法專利的侵權判斷 - 專利

引用一下爬到的claim

US Ptaent Issued 5,443,036
Abstract

A method for inducing cats to exercise consists of directing a beam
of invisible light produced by a hand-held laser apparatus onto the floor
or wall or other opaque surface in the vicinity of the cat, then moving
the laser so as to cause the bright pattern of light to move in an
irregular way fascinating to cats, and to any other animal with a
chase instinct.

就我所知，在進行侵權判斷前要先解讀專利申請範圍，

列出主要元件，次要元件，關係，步驟等以利之後的全要件判斷

問題一 請問每個步驟的句子是當成另外一個大元件看待嗎??
(也就是說上列專利可視為有一個元件叫做method，
其跟另外一個元件directing a xxxx 有consist of 的關係??)

問題二 判斷步驟是否相等時要考慮是何主體進行該步驟嗎?
(就是說需要考慮是什麼主詞進行上列步驟的黃色動作嗎?)

抱歉小弟不是很了解，以上如有觀念錯誤，請多多指教XDXD
