Internal Confidential Documents Not Public
Note:
Documents distributed internally and intended to remain confidential are not considered printed publications, even if many copies are distributed.

Documents and items only distributed internally within an organization which are intended to remain confidential are not “printed publications” no matter how many copies are distributed. There must be an existing policy of confidentiality or agreement to remain confidential within the organization. Mere intent to remain confidential is insufficient. In re George, 2 USPQ2d 1880 (Bd. Pat. App. & Inter. 1987) (Research reports disseminated in-house to only those persons who understood the policy of confidentiality regarding such reports are not printed publications even though the policy was not specifically stated in writing.); Garret Corp. v. United States, 422 F.2d 874, 878, 164 USPQ 521, 524 (Ct. Cl.1970) (“While distribution to government agencies and personnel alone may not constitute publication… distribution to commercial companies without restriction on use clearly does.”); Northern Telecom Inc. v. Datapoint Corp., 908 F.2d 931, 15 USPQ2d 1321 (Fed. Cir. 1990) (Four reports on the AESOP-B military computer system which were not under security classification were distributed to about fifty organizations involved in the AESOP-B project. One document contained the legend “Reproduction or further dissemination is not authorized.” The other documents were of the class that would contain this legend. The documents were housed in Mitre Corporation’s library. Access to this library was restricted to those involved in the AESOP-B project. The court held that public access was insufficient to make the documents “printed publications.”).

Doctoral Thesis as Printed Publication
Note:
A doctoral thesis indexed and shelved in a library is considered sufficiently accessible to the public, constituting prior art.

A doctoral thesis indexed and shelved in a library is sufficiently accessible to the public to constitute prior art as a “printed publication.” In re Hall, 781 F.2d 897, 228 USPQ 453 (Fed. Cir. 1986). Even if access to the library is restricted, a reference will constitute a “printed publication” as long as a presumption is raised that the portion of the public concerned with the art would know of the invention. In re Bayer, 568 F.2d 1357, 196 USPQ 670 (CCPA 1978).

Fourteen-Slide Presentation Made Publicly Accessible at Industry Events
Note:
A fourteen-slide presentation disclosing the invention was printed and pasted onto poster boards and displayed for three cumulative days at two industry events without confidentiality restrictions.

As stated in In re Klopfenstein, 380 F.3d 1345, 1348, 72 USPQ2d 1117, 1119 (Fed. Cir. 2004), “the key inquiry is whether or not a reference has been made ‘publicly accessible.’” Prior to the critical date, a fourteen-slide presentation disclosing the invention was printed and pasted onto poster boards. The printed slide presentation was displayed with no confidentiality restrictions for approximately three cumulative days at two different industry events. Id. at 1347, 72 USPQ2d at 1118. The court noted that “an entirely oral presentation at a scientific conference that includes neither slides nor copies of the presentation is without question not a 'printed publication' for the purposes of [pre-AIA] 35 U.S.C. § 102(b). Furthermore, a presentation that includes a transient display of slides is likewise not necessarily a ‘printed publication.’” Id. at 1349 n.4, 72 USPQ2d at 1120 n.4. In resolving whether or not a temporarily displayed reference that was neither distributed nor indexed was nonetheless made sufficiently publicly accessible to count as a “printed publication” under pre-AIA 35 U.S.C. 102(b), the court considered the following factors: “the length of time the display was exhibited, the expertise of the target audience, the existence (or lack thereof) of reasonable expectations that the material displayed would not be copied, and the simplicity or ease with which the material displayed could have been copied.” Id. at 1350, 72 USPQ2d at 1120. Upon reviewing the above factors, the court concluded that the display “was sufficiently publicly accessible to count as a ‘printed publication.’” Id. at 1352, 72 USPQ2d at 1121.

Online Database Document Not Always a Printed Publication
Note:
A document in an online database is not always considered a printed publication if it cannot be easily found by a skilled artisan using reasonable diligence.

A document in an online database is not always deemed a printed publication. In Acceleration Bay, LLC v. Activision Blizzard Inc., 908 F.3d 765, 773, USPQ2d 1507, 1514 (Fed. Cir. 2018), the court agreed with the Board that an electronic technical report did not constitute a “printed publication” within the meaning of (pre‑AIA) 35 U.S.C. 102(a). The court agreed with the Board that an interested skilled artisan, using reasonable diligence, would not have been able to find the technical report on the CSE Technical Reports Library website despite some indexing and search functionality on the website that permitted technical accessibility. Technical reports were listed only by author or year, and there was no evidence how many reports were in the Library’s database in 1999. It was determined that at best, an artisan might have located the cited technical report by skimming through potentially hundreds of titles in the same year, with most containing unrelated subject matter, or by viewing all titles in the database listed by author, when the authors were not particularly well known. Also, the website’s advanced search form was found to be deficient because the ability to search keywords for author, title, and abstract fields was not reliable.

Public Accessibility Requirement

[mpep-2128-01-a61fe3de4fa943363bf96822]
Requirement for Publicly Accessible Reference Display
Note:
The rule requires determining if a reference was publicly accessible by considering factors like display duration, audience expertise, and ease of copying.

As stated in In re Klopfenstein, 380 F.3d 1345, 1348, 72 USPQ2d 1117, 1119 (Fed. Cir. 2004), “the key inquiry is whether or not a reference has been made ‘publicly accessible.’” Prior to the critical date, a fourteen-slide presentation disclosing the invention was printed and pasted onto poster boards. The printed slide presentation was displayed with no confidentiality restrictions for approximately three cumulative days at two different industry events. Id. at 1347, 72 USPQ2d at 1118. The court noted that “an entirely oral presentation at a scientific conference that includes neither slides nor copies of the presentation is without question not a 'printed publication' for the purposes of [pre-AIA] 35 U.S.C. § 102(b). Furthermore, a presentation that includes a transient display of slides is likewise not necessarily a ‘printed publication.’” Id. at 1349 n.4, 72 USPQ2d at 1120 n.4. In resolving whether or not a temporarily displayed reference that was neither distributed nor indexed was nonetheless made sufficiently publicly accessible to count as a “printed publication” under pre-AIA 35 U.S.C. 102(b), the court considered the following factors: “the length of time the display was exhibited, the expertise of the target audience, the existence (or lack thereof) of reasonable expectations that the material displayed would not be copied, and the simplicity or ease with which the material displayed could have been copied.” Id. at 1350, 72 USPQ2d at 1120. Upon reviewing the above factors, the court concluded that the display “was sufficiently publicly accessible to count as a ‘printed publication.’” Id. at 1352, 72 USPQ2d at 1121.

Note:
The reference must be accessible to the public interested in the art before the critical date for it to be considered a printed publication.

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.” Constant v.

Access to AESOP-B Project Library Restricted
Note:
The library containing documents for the AESOP-B project was accessible only to those involved in the project, ensuring confidentiality.

Documents and items only distributed internally within an organization which are intended to remain confidential are not “printed publications” no matter how many copies are distributed. There must be an existing policy of confidentiality or agreement to remain confidential within the organization. Mere intent to remain confidential is insufficient. In re George, 2 USPQ2d 1880 (Bd. Pat. App. & Inter. 1987) (Research reports disseminated in-house to only those persons who understood the policy of confidentiality regarding such reports are not printed publications even though the policy was not specifically stated in writing.); Garret Corp. v. United States, 422 F.2d 874, 878, 164 USPQ 521, 524 (Ct. Cl.1970) (“While distribution to government agencies and personnel alone may not constitute publication… distribution to commercial companies without restriction on use clearly does.”); Northern Telecom Inc. v. Datapoint Corp., 908 F.2d 931, 15 USPQ2d 1321 (Fed. Cir. 1990) (Four reports on the AESOP-B military computer system which were not under security classification were distributed to about fifty organizations involved in the AESOP-B project. One document contained the legend “Reproduction or further dissemination is not authorized.” The other documents were of the class that would contain this legend. The documents were housed in Mitre Corporation’s library. Access to this library was restricted to those involved in the AESOP-B project. The court held that public access was insufficient to make the documents “printed publications.”).
