Abstract
The statements, "The laws of nature," "the principles of nature," "the fundamental truths," etc., are not patentable, have been oft repeated but seldom understandingly used. They have led to misunderstanding and much confusion, not limited to members of the bar. In fact, the words... are all words of broad and also elastic meaning and are frequently used carelessly and without any attempt at refined distinctions.
