In 1971, the owners of the copyright in the 60s hit "He's So Fine" sued former Beatle, George Harrison, over the song "My Sweet Lord."

In 1990, the owners of the copyright in the 60s hit "Oh, Pretty Woman," sued the rap group 2 Live Crew over a song cleverly entitled "Pretty Woman."

One of these cases resulted in an award over $1/2 million

The other case resulted in nothing.

Why?.

The answer can be attributed to the differences between plagiarism and fair use.

Plagiarism is an ethical issue. Copyright infringement and fair use are legal issues.

Plagiarism is an act of academic dishonesty.

As defined by the Wikipedia, it is:

"the use of another's information, language, or writing. . . without proper acknowledgment of the original source . . . dishonesty in attempting to pass of the plagiarized work as original."

In contrast, copyright is a legal right that arises from the U.S. Constitution, which states:

"the Congress shall have the power . . . to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."

The biggest difference can be seen in what is protected by copyright.

Copyright protects any "original work of authorship fixed in any tangible medium of expression."

A wide variety of works are protected – literary works to architectural works.

The important thing to recognize is what is not protected.

Copyright law does not protect ideas, concepts, facts or discoveries. It only covers original expression.

The scope of protection extends not merely to exact copies but also to derivative works, which means anything based on a protected work, translations, screenplays, adaptations.

The test for infringement is simply this:

Did the defendant have access to the original work?

Are the two works substantially similar in protectable elements?

And there lies the important difference between plagiarism and copyright infringement.

Plagiarism includes taking another's ideas, concepts and information without attribution. Taking expression adds to the wrong, but is not required.

For copyright infringement, attribution is not relevant. Using the ideas, concepts and information of another is not infringement. Only taking expression is infringement. And once you take expression, attribution is not a cure.

As for our rock stars?  George Harrison's song "My Sweet Lord" was the infringement.  You can find audio samples here and here and here and decide for yourself.
