目前常見的專利授權契約之類型有：專屬授權契約、非專屬授權契約、獨家授權契約、交互授權契約與回饋授權契約。雖然以前已有多篇文獻探討專利授權契約，但對於契約內容及相關權利義務之約定仍未臻明確，致爭議頻生，例如專利授權之授權人對於專利技術或權利的瑕疵擔保責任之有無或應負擔至何種程度，學說上仍見解分歧，本文將予論述並提出管見。即本文係以專利授權契約為標的，探討專利授權在民法下之制度設計，及專利授權契約之架構與契約條款設計。在授權關係中，應區分授權行為與授權契約之不同概念，尤其對於授權契約的法律性質、類型及要件、效果。當事人究竟應選擇何種契約，應考量專利權範圍、專利權效力範圍及專利技術之實施價值及資本、獲利等；俾能準確客觀評估該專利技術的市場競爭力，當事人雙方的締結專利授權契約意願，並對於風險事前評估，以利在契約條文中儘可能對釐清雙方的權利義務關係及未來發生爭議的解決方式。文末則以兩個法院判決實務，分析專利權撤銷對契約瑕疵擔保責任或權利金給付的效力。
