Piano roll blues

The Piano Roll Blues or Old Piano Roll Blues is a figure of speech designating a legal argument (or the response to that argument) made in US patent law relating to computer software. The argument is that a newly programmed general-purpose digital computer is a "new" machine and, accordingly, properly the subject of a US patent.[1]

Detail of player piano roll being operated by player piano, turning player piano into a "new and different machine"

This legal argument was made in Gottschalk v. Benson in Benson's brief. The government then responded in its brief that this amounted to asserting that inserting a new piano roll into an existing player piano converted the old player piano into a new player piano.[2] After Benson, the Court of Customs and Patent Appeals 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.[3] 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.

The argument appeared again two decades later in the majority opinion in In re Alappat,[4] and in his dissenting opinion in that case Chief 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.[5]

Despite a strong indication in the Supreme Court's Gottschalk v. Benson 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.[6] A very recent example was in a dissenting opinion of Chief Judge Rader in 2013.[7]

The Supreme Court's opinion in the Alice case[8] 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.[9]

The expression apparently derives from a song popular in the 1950s—"The Old Piano Roll Blues" by Cy Coben[10] — in the style of a Scott Joplin rag. As Judge Archer points out in his Alappat dissent, there is also an allusion to the decision of the Supreme Court in White-Smith v. Apollo, concerning copyright protection for piano rolls.
