Trade-Mark Cases — Syllabus
(1879)
“ True, such trade and intercourse must be foreign, or among the citizens of the different States, or with the Indian tribes; but if the instrumentalities employed as aids to such trade and commerce are not local in their operation and are of such a nature as to admit of uniformity of regulation, the power of Congress not only applies to them, but is exclusive.2. Trade-marks are important instrumentalities, aids, or appliances by which trade, especially in modern times, is conducted. They are the means by which manufacturers and merchants identify their manufactures and merchandise. ”
