SUMMARY OF RULING
So long as the specific code used to implement a method is different, anyone is free
under the Copyright Act to write his or her own code to carry out exactly the same function
or specification of any methods used in the Java API. It does not matter that the declaration or
method header lines are identical. Under the rules of Java, they must be identical to declare a
method specifying the same functionality even when the implementation is different.
When there is only one way to express an idea or function, then everyone is free to do so and
no one can monopolize that expression. And, while the Android method and class names could
have been different from the names of their counterparts in Java and still have worked, copyright
protection never extends to names or short phrases as a matter of law.
It is true that the very same functionality could have been offered in Android
without duplicating the exact command structure used in Java. This could have been doneby re-arranging the various methods under different groupings among the various classes and
packages (even if the same names had been used). In this sense, there were many ways to group
the methods yet still duplicate the same range of functionality.
But the names are more than just names they are symbols in a command structure
wherein the commands take the form
java.package.Class.method()
Each command calls into action a pre-assigned function. The overall name tree, of course, has
creative elements but it is also a precise command structure a utilitarian and functional set
of symbols, each to carry out a pre-assigned function. This command structure is a system or
method of operation under Section 102(b) of the Copyright Act and, therefore, cannot be
copyrighted. Duplication of the command structure is necessary for interoperability.
