"I do not think that a Judge would wish any statement which he may have made in the course of a case, merely obiter and casually, to be treated as necessarily being an authority on the subject in question; but when a Judge has thought it necessary for the purpose of a case to make a deliberate examination of the practice of his Court, and to state such practice, I do not think the authority of such statement can be got rid of merely by arguing that it was not really necessary for the actual decision of the case. I think that such a statement if cited as an authority is entitled to great weight, though of course not binding on us as a decision."

“To my mind when a great Judge, a master of the whole subject, thinking it necessary for the decision of the case to carefully examine into and to state the practice, it is nothing to say as against that, that it was not necessary for the decision.”

“It seems to me that whenever circumstances arise in the ordinary business of life in which, if two persons were ordinarily honest and careful, the one of them would make a promise to the other, it may properly be inferred that both of them understood that such a promise was given and accepted.”

“Well, then, the moment there is a patent case one can see it before the case is opened, or called in the list. How can we see it? We can see it by a pile of books as high as this invariably... Now, what is the result of all this? Why that a man had better have his patent infringed, or have anything happen to him in this world, short of losing all his family by influenza, than have a dispute about a patent. His patent is swallowed up, and he is ruined. Whose fault is it? It is really not the fault of the law; it is the fault of the mode of conducting the law in a patent case. This is what causes all this mischief.”

“Personally, I detest any attempt to bring the law into maxims. Maxims are invariably wrong, that is, they are so general and large that they always include something which is not intended to be included.”

“Parties cannot by consent give to the Court a power which it would not have without it.”

“An amendment ought not to be allowed if it will occasion injustice; but if it can do no injustice, and will only save expense, it ought to be made.”
