Conceptual similarity
The most subtle type: two trademarks sound different and are spelled differently – but mean the same thing. When the meaning matches, a conceptual likelihood of confusion can arise.
When meaning connects
There is conceptual (semantic) similarity when two signs convey the same content of meaning. This can happen via synonyms ("Sunbeam" and "Solar Light"), via translations into another language ("Apfel" and "Apple") or via the same visual concept. The public then makes a mental connection, even though sound and spelling differ.
"Apfel" and "Apple" – same idea, two languages
Different language, identical conceptual content: precisely here a conceptual likelihood of confusion can arise. Meaning beats spelling.
Example
This is what a semantic alert looks like
Examples
Apple went after the apple logo of a Bonn café, invoking the fame of its own trademark. After a long dispute, the group backed down.
The lesson: Well-known trademarks monitor conceptual and visual proximity very closely.
DPMA proceedings, 2011–2013
Apple opposed the pear-shaped logo of the recipe app Prepear – fruit concept against fruit concept.
The lesson: Even related visual concepts can be a source of conflict.
USPTO proceedings, settlement 2021
Different words, the same image in mind – this can create a connection.
The lesson: Synonyms and relatedness of meaning count.

The most demanding examination
Semantic similarity is practically impossible to find with a keyword search – it requires an understanding of meaning. Our Pro plan includes this conceptual level and thus closes the gap left by purely text-based monitoring.
