評析：本文彙整崇貿科技與Power Integrations公司基本資料與專利核准狀況。

崇貿科技公司英文名稱為System General Corp.（http://www.sg.com.tw/），公司基本介紹如下[1]：

崇貿科技成立於1983年，初期以提供電源供應器與電子儀器之設計服務為主，在累積相當技術後，開始發展自有品牌之IC測試與編程器（Tester & Programmer）及全自動之取置設備（Handler），多年來崇貿在此利基市場以自創品牌行銷全球，成功地得到國內外知名大廠之肯定及採用。

而在電源供應器部分，崇貿初期專注於高可靠、高性能之電源供應器的設計服務，其間並曾參與IDF（經國號戰機）之座艙控制系統電源供應器研發，且通過嚴格認證成為合格之航空電子供應商。

近年來有鑑於我國半導體產業分工體系日趨完整，且前後段生產製造能力之連貫逐步成熟，崇貿於是在1999年正式跨入IC設計產業，鎖定本公司已具備豐富經驗的電源供應器產業，矢志成為其核心元件－電源IC－之領導廠商。崇貿科技電源IC系列產品於2002年陸續上市，目前已廣泛被國內各大電源製造廠採用，其應用範疇包括各種電腦、週邊、無線通訊器材及家電之電源管理系統。

崇貿科技電源供應器（含電源IC）相關中華民國核准專利彙整如表一，全部美國核准專利如表二。

Power Integrations（http://www.powerint.com/）公司介紹如下：

Power Integrations, Inc., (Nasdaq: POWI) founded in 1988, is the leading supplier of high-voltage analog integrated circuits (ICs) used in power conversion. Power Integrations ICs enable compact, lightweight power supplies that are simpler to design and manufacture, more reliable, and more energy-efficient than those made with competing technologies. Our ICs power a vast range of consumer and industrial electronics - computers, DVD players, TV set-top boxes, cell phone chargers, home appliances, telecom networking equipment, and many others.

Power Integrations（PI）近期美國核准專利（二十筆）彙整如表三，PI各國專利佈局如表四。(1321字)
