In re Nuijten: Patentable Subject Matter, Textualism and the Supreme Court

DuffyBy Professor John F. Duffy, George Washington University

[PDF Version of this Post] In re Nuijten, which is being argued to the Federal Circuit today, presents the important issue of whether a new type of artificially constructed signal may be patented.  The Patent and Trademark Office opposes patentability on the grounds that, as a matter of textual interpretation, signals do not fall within any one of the four categories of patentable subject matter - "process, machine, manufacture, or composition of matter" - identified in section 101 of the Patent Act.  PTO Br. at 12 (quoting 35 U.S.C. § 101).  Though Nuijten raises important issues concerning the scope of patentable subject matter under U.S. law (and that's reason enough for most patent practitioners and scholars to care about its outcome), the case is also about much more.  It is about the fundamental approach to interpreting the Patent Act and the effect of the Supreme Court's recent interest in patent cases.  To appreciate those larger issues, we must begin with a basic understanding of the facts at issue.

PatentlyO2006044Modern signals (e.g., for carrying audio, video or data) may be constructed to contain embedded "supplemental data" or "watermarks," which typically contain information such as the source or copyright status of the underlying information being transmitted.  The addition of such watermarks, which is old in the art, can distort the underlying signal.  Nuijten invented a new way to add watermarks that results in less distortion.  Nuijten filed a patent application with claims directed to (1) the new process for adding watermarks, (2) storage media containing signals encoded by the new process, and (3) the signals themselves.  The PTO has allowed claims for the process and for the storage media containing the signals, but not for the signals themselves.  The PTO does not disputed that the signals sought to be patented are demonstrably new and nonobvious.  The agency's sole objection rest on section 101 of the Patent Act.

Wegner: Escaping the Depths of the Patent Shadows

WegnerA response to Merges,
By Hal Wegner

Professor Robert P. Merges makes much sense in his op-ed piece, Back to the Shadows, or Onward and Upward? Current Trends in Patent Law. We and thoughtful supporters of the patent system share much common ground.  Professor Merges touches on numerous points where there is hardly any significant difference with this writer, including the domestic results of the eBay decision from last year.  In his analysis of the Supreme Court, Professor Merges is correct that the Court is generally “pro business”, but it is another matter whether in some industries being “pro business” means being “pro-patent”.

PatentlyO2006026“Pro Business” as Anti-Patent, a new Direction at the Court:  Professor Merges is absolutely correct that the Supreme Court today is “pro-business”.  Whether the majority is pro-patent is possible but not yet conclusively determined: It is too soon to tell. It is undeniable that there is a solid, anti-patent Supreme Court core consisting of Justices Breyer and Stevens.  Justice Stevens’ anti-patent record reaches back to the mid-1970’s and is too well documented to question.  Yet, Justice Breyer is apparently now the more enthusiastic anti-patent of the two; they are the only members of the Court in this century to have taken the view that the open door to § 101 patent-eligibility for “living” inventions in the Chakrabarty case should be narrowed, arguing in a dissent in J.E.M. that the utility patent law “does not apply to plants”.(1) Just last year, an anti-patent drumbeat manifested in the Breyer dissent from the Metabolite “DIG” (joined by Stevens) plus their joint participation in the Justice Kennedy concurrence in eBay further validates their anti-patent bias.  Justice Souter joined both the Metabolite DIG dissent and the Kennedy eBay concurrence, but whether he is truly a solid part of an anti-patent core requires more data points; they may be forthcoming in shortly in KSR and in early Spring in Microsoft.  Whether other members of the Court join this core remains to be seen.

Feeding this nascent anti-patent core are two dominant themes:  First, while the Supreme Court is pro-business, a major segment of the business community is largely anti-patent, turning the patent system upside down:  Under this twisted view of patents, being “anti-patent” may be “pro business”.  Second, the patent jurisprudence of the Federal Circuit has created and continues to create problems that necessarily fuel further growth of an anti-patent sentiment.
