Henkel v. Procter & Gamble on reduction to practice

Interference 105,174 turned on the relation between "reduction to practice" and the interference count; the subject matter is laundry tablets.

The case gets into the appreciation by the inventors of WHAT they had invented contemporaneously with conception and reduction to practice. Invitrogen, 429 F.3d 1052.

There is language "this is not a case in which there is a danger that inventors unwittingly and accidentally created something new."

There was also an issue of corroboration.
