Experimentation Intent Requires Objective Evidence
Note:
An inventor's secret intent to experiment is not sufficient; objective evidence and customer awareness are required when goods are sold in a commercial environment.

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention. Under such circumstances, the customer at a minimum must be made aware of the experimentation.” LaBounty Mfg., Inc. v. United States Int’l Trade Comm’n, 958 F.2d 1066, 1072, 22 USPQ2d 1025, 1029 (Fed. Cir. 1992) (quoting Harrington Mfg. Co. v. Powell Mfg. Co., 815 F.2d 1478, 1480 n.3, 2 USPQ2d 1364, 1366 n.3 (Fed. Cir. 1986); Sunoco Partners Mktg. & Terminals LP v. U.S. Venture, Inc., 32 F.4th 1161, 1171-72, 2022 USPQ2d 417 (Fed. Cir. 2022) (The Federal Circuit relied on the objective evidence of the contract over the inventors’ testimony that their intent for the agreement was experimental); Paragon Podiatry Laboratory, Inc. v. KLM Labs., Inc., 984 F.2d 1182, 25 USPQ2d 1561 (Fed. Cir. 1993) (Paragon sold the inventive units to the trade as completed devices without any disclosure to either doctors or patients of their involvement in alleged testing. Evidence of the inventor’s secretly held belief that the units were not durable and may not be satisfactory for consumers was not sufficient, alone, to avoid a statutory bar.).

Customer Must Be Informed of Experimentation
Note:
When goods are sold in a commercial environment, customers must be informed if the product is being tested. The inventor's subjective intent alone is not sufficient to avoid statutory bars.

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention. Under such circumstances, the customer at a minimum must be made aware of the experimentation.” LaBounty Mfg., Inc. v. United States Int’l Trade Comm’n, 958 F.2d 1066, 1072, 22 USPQ2d 1025, 1029 (Fed. Cir. 1992) (quoting Harrington Mfg. Co. v. Powell Mfg. Co., 815 F.2d 1478, 1480 n.3, 2 USPQ2d 1364, 1366 n.3 (Fed. Cir. 1986); Sunoco Partners Mktg. & Terminals LP v. U.S. Venture, Inc., 32 F.4th 1161, 1171-72, 2022 USPQ2d 417 (Fed.

Sales Must Disclose Experimental Status
Note:
When goods are sold in a commercial environment, inventors must disclose that the products are experimental to avoid statutory bars.

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention. Under such circumstances, the customer at a minimum must be made aware of the experimentation.” LaBounty Mfg., Inc. v.

Secretly Held Beliefs Are Insufficient Without Evidence
Note:
The secretly held belief of an inventor that a product may not be durable is insufficient to avoid statutory bars without objective evidence and customer awareness.

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention. Under such circumstances, the customer at a minimum must be made aware of the experimentation.” LaBounty Mfg., Inc. v.
