2133.03 Rejections Based on "Public Use" or "On Sale" [R-5] - 2100 Patentability
2133.03 Rejections Based on "Public Use" or "On Sale" [R-5]
35 U.S.C. 102(b) "contains several distinct bars to patentability, each of which relates to activity or disclosure more than one year prior to the date of the application. Two of these - the 'public use' and the 'on sale' objections - are sometimes considered together although it is quite clear that either may apply when the other does not." Dart Indus. v. E.I. du Pont de Nemours & Co., 489 F.2d 1359, 1365, 179 USPQ 392, 396 (7th Cir. 1973). There may be a public use of an invention absent any sales activity. Likewise, there may be a nonpublic, e.g., "secret," sale or offer to sell an invention which nevertheless constitutes a statutory bar. Hobbs v. United States, 451 F.2d 849, 859-60, 171 USPQ 713, 720 (5th Cir. 1971).
In similar fashion, not all "public use" and "on sale" activities will necessarily occasion the identical result. Although both activities affect how an inventor may use an invention prior to the filing of a patent application, "non-commercial" 35 U.S.C. 102(b) activity may not be viewed the same as similar "commercial" activity. See MPEP § 2133.03(a) and § 2133.03(e)(1). Likewise, "public use" activity by an applicant may not be considered in the same light as similar "public use" activity by one other than an applicant. See MPEP § 2133.03(a) and § 2133.03(e)(7). Additionally, the **>concept of< "experimental use" **>may have different< significance in "commercial" and "non-commercial" environments. See MPEP § 2133.03(c) and § 2133.03(e) - § 2133.03(e)(6).
It should be noted that 35 U.S.C. 102(b) may create a bar to patentability either alone, if the device in public use or placed on sale anticipates a later claimed invention, or in conjunction with 35 U.S.C. 103, if the claimed invention would have been obvious from the device in conjunction with the prior art. LaBounty Mfg. v. United States Int'l Trade Comm'n, 958 F.2d 1066, 1071, 22 USPQ2d 1025, 1028 (Fed. Cir. 1992).
POLICY CONSIDERATIONS
(A) "One policy underlying the [on-sale] bar is to obtain widespread disclosure of new inventions to the public via patents as soon as possible." RCA Corp. v. Data Gen. Corp., 887 F.2d 1056, 1062, 12 USPQ2d 1449, 1454 (Fed. Cir. 1989).
(B) Another policy underlying the public use and on-sale bars is to prevent the inventor from commercially exploiting the exclusivity of his [or her] invention substantially beyond the statutorily authorized period. RCA Corp. v. Data Gen. Corp., 887 F.2d 1056, 1062, 12 USPQ2d 1449, 1454 (Fed. Cir. 1989). See MPEP § 2133.03(e)(1).
(C) Another underlying policy for the public use and on-sale bars is to discourage "the removal of inventions from the public domain which the public justifiably comes to believe are freely available." Manville Sales Corp. v. Paramount Sys., Inc., 917 F.2d 544, 549, 16 USPQ2d 1587, 1591 (Fed. Cir. 1990).
