Company Name Conflict Checker
Search Companies House and the Charity Commission for names similar to your proposed brand. See how they overlap with existing trademark registrations.
Why check company names before filing a trademark?
Even if a name is clear on the trademark register, an existing company using the same or a similar name can challenge your registration through passing off claims. UK law protects unregistered rights built through genuine trading.
Prior Use Risk
A company trading under a name for years can oppose your trademark even without a registration of their own.
SIC → Nice Mapping
We map company SIC codes to Nice trademark classes to identify industry overlap.
Charity Coverage
Registered charities often have strong brand equity. We check the Charity Commission register too.
Frequently Asked Questions
Can a company oppose my trademark?
Yes. If a company has been trading under a name and has built goodwill, they may challenge your trademark application through passing off or an opposition based on earlier rights.
What are SIC codes and Nice classes?
SIC codes classify the economic activity of UK companies. Nice classes classify goods and services for trademark registration. We approximate the mapping between them to identify potential overlap.
