took the position that the reasoning of ''Benson'' did not apply to "machine" claims, such as a claim to a conventional digital computer programmed to carry out a new algorithm or computer program. In dissenting from that judgment on the grounds that the Supreme Court in ''Benson'' did not limit the principle to method claims, Judge Rich spoke of "the legal doctrine that a new program makes an old general purpose digital computer into a new and different machine." ''Id''. at 773. He observed that the doctrine "partakes of the nature of a legal fiction when it comes to drafting claims." ''Id''.

Judge Archer discussed the figure of speech extensively, concluding:
Yet a player piano playing Chopin's scales does not become a "new machine" when it spins a roll to play Brahms' lullaby. The distinction between the piano before and after different rolls are inserted resides not in the piano's changing quality as a "machine" but only in the changing melodies being played by the one machine. The only invention by the creator of a roll that is new because of its music is the new music.

'' opinion that computer implementation of an otherwise patent-ineligible abstract idea (in that case a mathematical algorithm) was insufficient to transform the idea into patent-eligible subject matter, the Federal Circuit continued sporadically to assert the piano roll blues argument. A very recent example was in a dissenting opinion of Chief Judge Rader in 2013.
The Supreme Court's opinion in the
''Alice'' case may have finally put a stop to the piano roll blues argument, since it states that simply saying "apply it with a computer" will not transform a patent-ineligible claim to an idea into a patent-eligible claim.
