Key Theses
- The designation ROBOROCK ZEO LITE was refused registration due to the alleged similarity to trademark No. 995507.
- Rospatent identified the fragment "ZEO" as the dominant element and considered it confusingly similar to the cited trademark.
- The applicant, Beijing Roborock Technology Co., Ltd., submitted an opposition challenging the dominance of "ZEO" and arguing that the mark must be assessed as a three-word combination.
- The Chamber for Patent Disputes upheld the refusal, confirming that the semantic and phonetic overlap of the elements "ZEO" and the cited mark creates a likelihood of confusion.
- This case reinforces Rospatent's established approach: in composite signs, a short arbitrary element may acquire dominance even in the presence of a strong initial word segment.
Legal Analysis
The dispute concerned the registrability of the designation ROBOROCK ZEO LITE in respect of goods in class 7. The examination division concluded that the designation is confusingly similar to trademark No. 995507 due to the presence of the element "ZEO", which was interpreted as phonetically and visually correlated with the cited mark.
The applicant argued that the sign forms a unified verbal sequence consisting of three independent components, each contributing to the overall structure. The element "ROBOROCK" allegedly possesses increased distinctiveness due to its association with the applicant's firm name and global brand identity. Therefore, the applicant contended that "ZEO" cannot be isolated for purposes of comparison.
Rospatent's assessment
Rospatent rejected these arguments, stating that:
- Consumers tend to perceive short arbitrary elements as significant identifiers.
- The presence of "ROBOROCK" does not neutralize the similarity created by "ZEO", because the initial element does not eliminate the dominant role of the middle fragment.
- The overall phonetic pattern of the sign, despite being three-part, retains an internal structure that allows "ZEO" to function independently in consumer perception.
Chamber for Patent Disputes
The Chamber for Patent Disputes confirmed that the cumulative similarity between "ZEO" and the cited mark is sufficient to establish a likelihood of confusion. Accordingly, the refusal of registration was upheld.
Patent Attorney Commentary
This decision once again demonstrates the rigidity of Rospatent's approach to evaluating composite verbal signs. The authority consistently isolates short, arbitrary fragments and assigns them dominant significance whenever they resemble previously registered marks.
From a practical standpoint, brand owners should consider the high evidentiary threshold required to prove that a multi-element designation is perceived as an inseparable whole. Even the presence of a globally recognized brand element ("ROBOROCK") did not prevent the authority from prioritizing an internal segment of the mark.
The decision also reflects an underlying systemic tendency: Russian practice gives substantial weight to the phonetic profile of short verbal fragments, even where such fragments are not independently meaningful. This creates elevated risks for applicants using invented syllabic structures similar to existing marks.
