Appeal No. 1999-1002 Application No. 08/672,493 circumstances of the use, which show the amount of control the inventor retained over the invention. See Moleculon Research v. CBS, Inc., 793 F.2d 1261, 1265, 229 USPQ 805, 809 (Fed. Cir. 1986), cert. denied, 479 U.S. 1030 (1987). In addition to the “general understanding of the confidential nature of the testing”, the circumstances of the testing indicate that the inventors maintained control over the invention. The examiner is basing his rejection on speculation that confidentiality “may” have been compromised. Absent any explanation or evidence, the examiner has failed to fulfill his initial burden of proving a case of public use more than one year prior to the application filing date. The circumstances of the experimentation indicate that the experimentation was under the control of the inventors. The field test sites were secure from the public, allowing access only to field test facility users and Xerox technicians. The users and technicians were under obligation to report field test rolls performance to the inventors. The inventors conducted on site inspection of the experimental rolls every six weeks. The inventor made provisions available to return the test rolls after the experimentation was concluded and a number of rolls were to be returned to Xerox. 17Page: Previous 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 NextLast modified: November 3, 2007
