Assignments and Licensing Overview 
作品讓與及授權概論

As an artist, one of the best ways to make money is to license or assign your work. Although many people use the terms interchangeably, there is a tremendous difference between licensing and assigning your art.
身為藝人，其中一種最棒的賺錢途徑，即是將自己的作品授權或讓與他人。雖然很多人會將現成的契約條款加以更改來利用，但是授權與讓與著作兩者是有很大之差異。

• Assignments: An assignment is basically handing your art over -- for good. Assigning your art to someone else gives them full ownership of the art, to do with as they please. There are plenty of good reasons to do this, but if you're going to give your art away for good, you should pay very close attention to what you're actually giving away.
  讓與：基本上讓與係將你作品移轉出去以換取利益。讓與你的作品予某人，是讓與作品的所有權；讓受讓人為符合其意願之事。有諸多好理由作為讓與所有權之依據，但讓與之前，你必須仔細考慮，你將讓與的標的是什麼，想清楚是讓與作品的所有權，例如如果是著作的話，你讓與的即是著作（財產）權，亦即之後該著作所有的著作財產權你都無法利用。
• Licenses: A license is more like renting your art out. It gives someone the rights to use your art for a limited time and for limited purposes while you, the artist, retain ultimate ownership of your art. Once the license expires, the licensee can no longer use your art.
• 授權：授權極近似出租你的作品；此賦予某人在授權契約所限制之期間及限制之目的下可利用該作品，然而創作人你仍保有該作品的所有權。一旦期間屆滿，被授權人不得再利用你的作品。

Unfortunately, many companies use terms like "exclusive licenses" for agreements that are actually assignments. Read the fine print carefully, and make sure you know exactly what you are, and aren't, giving away.
很不幸，許多公司在契約裏使用像〝專屬授權〞這種字眼，但探其本質，實乃讓與。請仔細研讀你的契約，確認你真正想交付出去或你不想交付出去的權利是什麼。

Reversions
權利回彈（以著作財產權為例）

A reversion is when something happens that causes the rights to your artwork to spring back to you. Knowing the difference between assignments and licenses, it should be apparent that most reversions should occur in licensing agreements. You grant a company a license to use your artwork for awhile, and then when some predetermined event or events happen, those rights terminate and flow back to you.
當有些約定事由發生，作品的權利將回歸於原創作者。以著作財產權為例，已知著作權之讓與與授權兩者間之差異，顯而易見權利回彈之情形，發生在著作財產權授權契約裏。作品創作者於一段期間內授權公司利用其作品，當一些契約預定事由或事由等發生，該等權利之利用即告終結並回彈於授權者通常是作品的創作者。
請尊重著作權，違法利用，本人必究。
