Genericide: The Transformation of Thermos

In the intricate world of trademark law, genericide presents a notable challenge, exemplified by the transformation of the term "Thermos" from a specific brand to a generic term. Initially a trademark of Thermos GmbH for their innovative vacuum flask, the word "Thermos" gradually became the default term for any similar product, regardless of the manufacturer. This shift in public perception and usage led to a pivotal legal decision in 1963, where "Thermos" was declared a generic term, highlighting the delicate balance between brand popularity and trademark protection.
