sbflcx.com is an intellectual property service website operated by Shanghai Cemeng Trademark Agency, positioned as both a trademark classification query tool and a full-process trademark registration agency service platform. It is a formal agency registered with the China National Intellectual Property Administration (CNIPA), and its core business is providing trademark registration-related consultation and agency services for domestic individuals and enterprises. The website fully syncs the 2026 version of CNIPA's 45-class trademark classification detailed data, and supports trademark classification search by industry and keyword.
The website's core functions are divided into two categories: First, free public trademark classification query, which covers annotations and group details for each of the 45 classes, helping applicants confirm the correct classification for their trademark in advance. Second, paid agency services, covering the full process of trademark registration application, trademark renewal, cancellation against non-use, review of refused registration, opposition response, trademark transfer and alteration. It claims to provide one-on-one consultant service with query responses delivered within 3 hours. The website does not publicly list specific pricing, only promises transparent pricing with no hidden fees, and quotes are only available via consultation over phone or WeChat.
Advantages: The agency is an officially registered service provider with formal qualification, its classification data is synced to the latest official version, the query function is free and easy to use, it can provide full-process trademark agency services, has multiple communication channels, and features relatively fast response times.
Disadvantages: The website layout has a large amount of duplicate content leading to poor user experience, service prices are not published publicly, users must contact a consultant to get a quote, there is no online self-service process, so it lacks convenience.
This website is suitable for domestic individual entrepreneurs and micro, small and medium-sized brand owners that are preparing to register a trademark. It is also available for consultation for users who need to handle post-registration trademark business, transfer or alteration. The website is a domestic service site, so Chinese users can access it directly and normally, and it supports query and use via a Chinese interface.
