Get a risk analysis report to prevent possible trademark infringements before you launch
CheckLine offers fixed-fee clearance searches for advertising slogans — also known as taglines, straplines, and endlines.
We handle the entire search — using trademark databases covering registered, pending, and expired trademarks, alongside our in-house database, which holds one of the largest and most up-to-date collections of slogans currently and historically used across industries worldwide.
You’ll receive a clear risk analysis report on trademarked and un-trademarked slogans based on your search requirements, with additional guidance from our expert team on next steps.
Test your ideas at the early stages of your campaign to avoid trademark infringements.

Unregistered ≠ Unused.
The majority of slogans used in advertisement campaigns aren’t registered trademarks, which means they cannot be found on trademark registers. But that doesn't make them safe to use.
At CheckLine, we go beyond the registers. Our in-house database tracks both registered and unregistered slogans drawn from campaigns across industries — updated weekly with hundreds of new entries. This gives you timely, relevant insight to help you make informed decisions at the early-stages of your campaign.
What's included in our services?
Each CheckLine search provides a practical assessment to help you identify potential conflicts before committing to the use of a phrase.​ We run the search for you, and give you our internal review of key findings, with commentary from our team to help guide you on next steps. This is presented through our risk analysis report, which includes our search results, identifying both exact hits and closely similar phrases of both trademarked (registered, pending, and expired trademarks) and un-trademarked slogans from our in-house database. This covers slogans used in current and previous advertising campaigns by local and global brands. Our report includes a clear presentation of our risk analysis, which organises relevant results associated with your slogan or keywords by our risk-rating system: Low, Medium, or High. Additionally, we give you a summary interpreting the results to support clear decision-making, and provide support for follow-up questions and queries, should you need help understanding the report or exploring your options.​
Our report covers slogans in the English language based on trademark clearance searches typically covering the following jurisdictions:
​
-
United Kingdom
-
Republic of Ireland
-
European Union
-
United States
-
Canada
-
Australia

​​
​We can also cover other territories designated under WIPO, based on your needs. If you require a specific jurisdiction not listed above, just let us know and we can tailor the search accordingly.​
​
Please note: CheckLine acts as a preliminary clearance tool to help screen ideas at the early stages of branding or campaign development. While our reports are designed to flag potential risks, they do not constitute legal advice and should not be relied upon as a legal clearance. We recommend seeking formal legal advice, and can connect you with trademark attorneys for legal guidance.​
Why Choose CheckLine ?
Specialised, Purpose-Built Database
What sets CheckLine apart is our ability to look beyond official trade mark registers. More than half of slogans and taglines used in advertising are never formally registered but still carry risks. Our proprietary in-house database tracks both registered and unregistered slogans used in the past and present across a wide range of industries. This gives you a more complete and updated insight of relevant slogans that have not been registered and therefore will not appear in trademark databases.

​
Early-Stage Insights for Campaign Idea Development
CheckLine also supports early-stage idea generation. If you haven’t settled on a specific phrase and want some inspiration, we can help you explore what's already out there by running a keyword-based search tailored to an industry of your choice, providing you with insight into how similar phrases have been used in past and current campaigns. This can help you identify overused language, spot gaps in the market, and shape a more distinctive message from the start.
​​
Actionable, Risk-Rated Reports
Our reports are designed for practical use. You’ll receive a clear, structured summary of relevant matches for your campaign or brand. If the report shows potential risk on your chosen slogan, we can advise you to seek legal advice from a trademark attorney. The reports are formatted for easy sharing whether it be internal teams, clients, or legal advisors.
