2133.03(e)(4) Factors Indicative of an Experimental Purpose [R-5]
The courts have considered a number of factors in determining whether a claimed invention was the subject of a commercial offer for sale primarily for purposes of experimentation. "These factors include: (1) the necessity for public testing, (2) the amount of control over the experiment retained by the inventor, (3) the nature of the invention, (4) the length of the test period, (5) whether payment was made, (6) whether there was a secrecy obligation, (7) whether records of the experiment were kept, (8) who conducted the experiment, ... (9) the degree of commercial exploitation during testing[,] ... (10) whether the invention reasonably requires evaluation under actual conditions of use, (11) whether testing was systematically performed, (12) whether the inventor continually monitored the invention during testing, and (13) the nature of contacts made with potential customers." Allen Eng'g Corp. v. Bartell Indus., Inc., 299 F.3d 1336, 1353, 63 USPQ2d 1769, 1780 (Fed. Cir. 2002) quoting EZ Dock v. Schafer Sys., Inc., 276 F.3d 1347, 1357, 61 USPQ2d 1289, 1296 (Fed. Cir. 2002) (Linn, J., concurring). >Another critical attribute of experimentation is the "customer's awareness of the purported testing in the context of a sale." Electromotive Div. of Gen. Motors Corp. v. Transportation Sys. Div. of Gen. Elec. Co., 417 F.3d 1203, 1241, 75 USPQ2d 1650, 1658 (Fed. Cir. 2005).<
Once alleged experimental activity is advanced by an applicant to explain a prima facie case under 35 U.S.C. 102(b), the examiner must determine whether the scope and length of the activity were reasonable in terms of the experimental purpose intended by the applicant and the nature of the subject matter involved. No one of, or particular combination of, factors is necessarily determinative of this purpose.
See MPEP § 2133.03(e)(1) for factors indicative of commercial exploitation.
