Genericide: The Decline of Cellophane
The term "Cellophane" is a classic example of genericide in trademark law, where a distinct brand name becomes a generic term for a broad category of products. Originally a trademark of DuPont for a novel transparent and flexible packaging material, "Cellophane" gradually became the generic term for any similar transparent film. This shift in usage not only diluted the brand's distinctiveness but also played a pivotal role in a landmark legal case, underscoring the complex interplay between market dominance, brand recognition, and trademark protection.
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.
