The Trademark That Lost Its Meaning
The word “Aspirin” was once a protected trademark owned by Bayer AG (German multinational life-science company). However, after World War I, Bayer lost its trademark rights in several countries, including the U.S., where “aspirin” became a generic term. This process, called “genericide” also affected brands like “escalator” and “cellophane.” It shows that trademark protection isn’t permanent if the public starts using your brand name as the product itself.
