As a result of this feature of the law products in various non-competitive lines sometimes bear the same names. There is, for example, a Yale[2] lock and a Yale motorcycle, an Ideal hairbrush and an Ideal fountain pen, a Packard piano and a Packard automobile, a Skidoo soap and a Skidoo Marine engine.
State Trade-Mark Laws
Most states have some kind of a trade-mark law, many of them good ones, and about a dozen have strong penal codes covering the subject, under the term of counterfeiting, while others are able to do what the United States courts cannot do—actually mete out imprisonment to those who infringe. Pennsylvania's law in this respect is particularly thorough.
The Federal statutes concerning trade-marks apply to the entire country. Few large concerns doing a national business register in the states. Most of them go to the Patent Office and secure national registration.
There is nothing in any of the state laws which make it safer to register by states, since California's obnoxious law has been repealed, but in some cases, where persistent infringers are at work, owners of trade-marks secure state registration as an extra precaution.
