Macmillan Co. v. King, 223 F. 862 (D. Mass 1914) was a copyright infringement case brought by a publisher of a two-volume economics textbook written by a Harvard University professor in the United States District Court for the District of Massachusetts. Note that this case was decided under previous statutory law and the law of fair use has evolved considerably since this case was decided.
The defendant was a private tutor that tutored students for preparation for their exams at Harvard. The defendant prepared one-page-long notes that were given at each conference the tutor had with his pupils to be used by his pupils in their studying for the examination. The type-written notes often followed the outline of the books; each student was required to purchase a copy of the book for the course they were taking. The notes were not for distribution to anyone else and the tutor stated that he demanded that the students return the typewritten looseleaf notes after they had completed their examinations in the course. The defendant's claim was that these notes were fair use.
The court analyzed the content of the notes and found that while they were not copies of the book, they had condensed the book in a manner that made it clear that the notes were nothing more than abridged versions of portions of the book. The summary of a chapter might be one paragraph long; within that paragraph it was structured in the same manner as the book. There were quotations from the book, though usually not more than one sentence long. The language used in the notes were similar to the language used in the textbooks. Sometimes there would be words without quotations taken from the textbooks, but this was never more than a few words long.
As District Judge Dodge states in his reasons (from 865-66):
This case shows that the analysis of copyright infringement is not a simple procedure based upon direct copying of material; it is also possible through paraphrasing and partial copying to be infringing on a copyright author’s work.
