2133.03(e)(3) "Completeness" of the Invention [R-3]
>I. < EXPERIMENTAL USE ENDS WHEN THE INVENTION IS ACTUALLY RE-DUCED TO PRACTICE
Experimental use "means perfecting or completing an invention to the point of determining that it will work for its intended purpose." Therefore, experimental use "ends with an actual reduction to practice." RCA Corp. v. Data Gen. Corp., 887 F.2d 1056, 1061, 12 USPQ2d 1449, 1453 (Fed. Cir. 1989). If the examiner concludes from the evidence of record that an applicant was satisfied that an invention was in fact "complete," awaiting approval by the applicant from an organization such as Underwriters' Laboratories will not normally overcome this conclusion. InterRoyal Corp. v. Simmons Co., 204 USPQ 562, 566 (S.D.N.Y. 1979); Skil Corp. v. Rockwell Manufacturing Co., 358 F. Supp. 1257, 1261, 178 USPQ 562, 565 (N.D.Ill. 1973), aff'd. in part, rev'd in part sub nom. Skil Corp. v. Lucerne Products Inc., 503 F.2d 745, 183 USPQ 396, 399 (7th Cir. 1974), cert. denied, 420 U.S. 974, 185 USPQ 65 (1975). ** See MPEP § 2133.03(c) for more information of what constitutes a "complete" invention.
The fact that alleged experimental activity does not lead to specific modifications or refinements of an invention is evidence, although not conclusive evidence, that such activity is not within the realm permitted by the statute. This is especially the case where the evidence of record clearly demonstrates to the examiner that an invention was considered "complete" by an inventor at the time of the activity. Nevertheless, any modifications or refinements which did result from such experimental activity must at least be a feature of the claimed invention to be of any probative value. In re Theis, 610 F.2d 786, 793, 204 USPQ 188, 194 (CCPA 1979).
>II. < DISPOSAL OF PROTOTYPES
Where a prototype of an invention has been disposed of by an inventor before the critical date, inquiry by the examiner should focus upon the intent of the inventor and the reasonableness of the disposal under all circumstances. The fact that an otherwise reasonable disposal of a prototype involves incidental income is not necessarily fatal. In re Dybel, 524 F.2d 1393, 1399, n.5, 187 USPQ 593, 597 n.5 (CCPA 1975). However, if a prototype is considered "complete" by an inventor and all experimentation on the underlying invention has ceased, unrestricted disposal of the prototype constitutes a bar under 35 U.S.C. 102(b). In re Blaisdell, 242 F.2d 779, 113 USPQ 289 (CCPA 1957); contra, Watson v. Allen, 254 F.2d 342, 117 USPQ 68 (D.C. Cir. 1958).
