“The Federal Circuit has made explicit what was implicit in our precedents. It has long held that “secret sales” can invalidate a patent. E.g., Special Devices, Inc. v. OEA, Inc., 270 F. 3d 1353 (2001) (invalidating patent claims based on “sales for the purpose of the commercial stockpiling of an invention” that “took place in secret”); Woodland Trust v. Flowertree Nursery, Inc., 148 F. 3d 1368 (1998) (“Thus an inventor’s own prior commercial use, albeit kept secret, may constitute a public use or sale under §102(b), barring him from obtaining a patent”). . . .

 

Given that the phrase “on sale” had acquired a well-settled meaning when the AIA was enacted, we decline to read the addition of a broad catchall phrase to upset that body of precedent.”
