“How much do you ask for it?”

“‘Ask for it?’ Ask for what?”

“For an interest in it, either a part or the whole?”

“What?”

“You ought to make a good thing out of it—out of your patent.”

“My patent! I haven’t any patent.”

“What! No patent?”

“No. It’s for the good of people generally.”

“But you got a patent?”

“No.”
