Q：教科書的內容是屬於公開信息，公開思想

A：出版的東西都是公開的。但是公開的不代表就是 public domain 了。

Q：筆記是對這種信息的一種歸納和改寫，從這個角度講似乎又不侵權。

A：歸納，改寫 is exactly what derivative works is about.

In the United States, the Copyright Act defines "derivative work" in 17 U.S.C. § 101:

A “derivative work” is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a “derivative work”.

Q：要到何種改寫程度才不能算derivative?

A：這是個 question of fact, 要打官司才能知道。 問題是，你願意冒這個風險嗎？ 別忘了，人家是有版權的。 就算你願意，你能找到願意冒這個風險的出版社嗎？

Q：你說“whether you have liability or not is a different question”又如何解釋？

A：是否侵權和如何賠償是兩個概念。 當然了，侵權是賠償的前提，但是這不代表侵權了就一定有賠償。 如果那本書在美國沒有注冊，按照版權法的規定，作者也還是有版權的，因為有沒有版權和有沒有注冊無關。 隻要寫出來，就有版權了。 但是如果他沒有注冊，就沒權力告你侵權，也談不上或得賠償。 可是你的確是侵權了。
