In Re Carol F. Klopfenstein and John L. Brent, Jr
Carol Klopfenstein and John Brent appeal a decision from the Patent and Trademark Office’s Board of Patent Appeals and Interferences (“Board”) upholding the denial of their patent application. The Board upheld the Patent and Trademark Office’s (“PTO’s”) initial denial of their application on the ground that the invention described in the patent application was not novel under
BACKGROUND
A.
The appellants applied for a patent on October 30, 2000. Their patent application, Patent Application Serial No. 09/699,-950 (“the ’950 application”), discloses methods of preparing foods comprising extruded soy cotyledon fiber (“SCF”). The ’950 application asserts that feeding mammals foods containing extruded SCF may help lower their serum cholesterol levels while raising HDL cholesterol levels. The fact that extrusion reduces cholesterol levels was already known by those of ordinary skill in the art that worked with SCF. What was not known at the time was that double extrusion increases
In October 1998, the appellants, along with colleague M. Liu, presented a printed slide presentation (“Liu” or “the Liu reference”) entitled “Enhancement of Cholesterol-Lowering Activity of Dietary Fibers By Extrusion Processing” at a meeting of the American Association of Cereal Chemists (“AACC”). The fourteen-slide presentation was printed and pasted onto poster boards. The printed slide presentation was displayed continuously for two and a half days at the AACC meeting.
In November of that same year, the same slide presentation was put on display for less than a day at an Agriculture Experiment Station (“AES”) at Kansas State University.
Both parties agree that the Liu reference presented to the AACC and at the AES in 1998 disclosed every limitation of the invention disclosed in the ’950 patent application. Furthermore, at neither presentation was there a disclaimer or notice to the intended аudience prohibiting note-taking or copying of the presentation. Finally, no copies of the presentation were disseminated either at the AACC meeting or at the AES, and the presentation was never catalogued or indexed in any library or database.
B.
On October 24, 2001, nearly one year after its filing, the ’950 patent application was rejected by the PTO examiner. The examiner found all of the application’s claims anticipated by the Liu reference or obvious in view of Liu and other references. Shortly thereafter, the appellants amended the claims of the ’950 patent and described the circumstances under which the Liu reference had been displayed to the AACC and at the AES. The appellants argued that the Liu reference was not a “printed publication” because no copies were distributed and because there was no evidence that the reference was photographed. The examiner rejected these arguments and issued a final office action on April 10, 2002 rejecting the claims of the ’950 application. The appellants then appealed to the Board.
Before the Board, the appellants again advanced their argument that the lack of distribution and lack of evidence of copying precluded the Liu reference from being considered a “printed publication.” The appellants further contended that the Liu reference was also not a “printed publication” because it was not catalogued or indexed in any library or database. The Board rejected the appellants’ arguments and affirmed the decision of the PTO examiner, finding the Liu reference to be a “printed publication.” The Board affirmed on the grounds that the full invention of the ’950 application was made publicly accessible to those of ordinary skill in the art by the Liu reference and that this introduction into the public domain of disclosed material via printed display represented a “printed publication” under
The appellants have appealed the Bоard’s decision to this court. We have jurisdiction to hear this appeal under
DISCUSSION
A.
Where no facts are in dispute, the question of whether a reference represents a “printed publication” is a question of law.
In
re
Cronyn,
The only question in this appeal is whether the Liu reference constitutes a “printed publication” for the purposes of
B.
The appellants argue on appeal that the key to establishing whether or not a reference constitutes a “printed publication” lies in determining whether or not it had been disseminated by the distribution of rеproductions or copies and/or indexed in a library or database. They assert that because the Liu reference was not distributed and indexed, it cannot count as a “printed publication” for the purposes of
We find the appellants’ argument unconvincing and disagree with their characterization of our controlling precedent. Even if the cases cited by the appellants relied on inquiries into distribution and indexing to reach their holdings, they do not limit this court to finding something to be a “printed publication” only when there is distribution and/or indexing. Indeed, the key inquiry is whether or not a reference has been made “publicly accessible.” As we have previously stated, ■
The statutory phrase “printed publication” has been interpreted to mean that before the critical date the reference must have been sufficiently accessible to the public interested in the art; dissemination and public accessibility are the keys to the legal determination whether a prior art reference was “published.”
In re Cronyn,
In Hall, this court determined that a thesis filed and indexed in a university library did count as a “printed publication.” The Hall court arrived at its holding after taking into account that copies of the indexed thesis itself were made freely available to the general public by the university more than one year before the filing of the relevant patent application in that case. But the court in Hall did not rest its holding merely on the indexing of the thesis in question. Instead, it used indexing as a factor in determining “public accessibility.” As the court asserted:
The [“printed publication”] bar is grounded on the principle that once an invention is in the public domain, it is no longer patentable by anyone.... Because there are many ways in which a refеrence may be disseminated to the interested public, “public accessibility” has been called the touchstone in determining whether a reference constitutes a “printed publication” bar under35 U.S.C. § 102(b) .
In re Hall,
In
MIT,
a paper delivered orally to the First International Cell Culture Congress was considered a “printed publication.” In that case, as many as 500 persons having ordinary skill in the art heard the presentation, and at least six copies of the paper were distributed. The key to the court’s finding was that actual copies of the presentation were distributed. The court did not consider the issue of indexing. The
MIT
court determined the paper in question to be a “printed publication” but did not limit future determinations of the applicability of the “printed publication” bar to instances in which copies of a reference werе actually offered for distribution.
MIT,
Finally, the
Wyer
court determined that an Australian patent application kept on microfilm at the Australian Patent Office was “sufficiently accessible to the public and to persons skilled in the pertinent art to qualify as a ‘printed publication.’ ”
In
Thus, throughout our case law, public accessibility has been the. criterion by which a prior art reference will be judged for the purposes of
C.
The determination of whether a reference is a “printеd publication” under
In this case, the Liu reference was displayed to the public approximately two years before the ’950 application filing date. The reference was shown to a wide variety of viewers, a large subsection of whom possessed ordinary skill in the art of cereal chemistry and agriculture. Furthermore, the reference was prominently displayed for approximately three cumulative days at AACC and the AES at Kansas State University. The reference was shown with no stated expectation that the information would not be copied or reproduced by those viewing it. Finally, no copies of the Liu display were distributed to the public and the display was not later indexed in any database, catalog or library.
Given that the Liu reference was never distributed to the public and was never indexed, we must consider several factors relevant to the facts of this case before determining whether or not it was sufficiently publicly accessible in order to be considered a “printed publication” undеr
The duration of the display is important in determining the opportunity of the public in capturing, processing and retaining the information conveyed by the reference. The more transient the display, the less likely it is to be considered a “printed publication.”
See, e.g., Howmedi-
The expertise of the intended audience can help determine how easily those who viewed it could retain the displayed material. As Judge Learned Hand explained in
Jockmus v. Leviton,
Whether a party has a reasonable expectation that the information it displays to the public will not be copied aids our
Finally, the ease or simplicity with which a display could be copied gives further guidance to our
Upon reviewing the above factors, it becomes clear that the Liu reference was sufficiently publicly accessible to count as a “printed publication” for the purposes of
CONCLUSION
For the aforementioned reasons, the decision of the Board is affirmed.
AFFIRMED.
Notes
. In their brief, the appellants note that there is scant legislative history to guide us in determining the meaning of the term "printed publication.” Accordingly, and rightfully, they have based the bulk of their argument on the controlling precedent of this court and its predecessor court.
. Appellants acknowledge that our precedent considers the term "printed publication” to be a unitary concept that may not correspond exactly to what the term "printed publication” meant when it was introduced into the patent statutes in 1836.
In re Wyer,
.While the Cronyn court held "dissemination” to be necessary to finding something to be a "printed publication”, the court there used the wоrd "disseminate” in its literal sense, i.e. "make widespread” or "to foster general knowledge of.” Webster's Third New International Dictionary 656 (1993). The court did not use the word in the narrower sense the appellants have employed it, which requires distribution of reproductions or photocopies.
. With regard to scientific presentations, it is important to note than an entirely oral presentation at a scientific conference that includes neithеr slides nor copies of the presentation is without question not a “printed publication” for the purposes of
. Unlike in Cronyn, it was the actual patent application — and not just an index card searchable by author name only — that was made publicly accessible.
