From one search term to a go/no-go signal.
See how the RodBooks workflow checks a single term, surfaces USPTO registration details when found, and points you to official databases for manual verification.
One safety workflow
Check before the title goes live.
Run distinctive words through the checker during research, especially before you finalize titles, series names, or subtitle phrases.
01
Enter one term
Type a single word or short phrase from your planned title, subtitle, or brand angle. Each search checks one term at a time.
02
Review USPTO results
RodBooks queries the USPTO trademark search API for live registrations and shows match status, registration details when available, and an active mark count.
03
Read the risk assessment
Get an overall risk level, high, medium, low, or none, plus an AI summary and recommendation written for KDP publishers, not lawyers.
04
Verify officially
Use the built-in links to USPTO TESS and EUIPO eSearch for manual confirmation. EUIPO guidance in the app is advisory, always verify separately.
Trademark screening workspace
Practical signals, not legal guarantees.
Combine live USPTO data, a known-brand safety list, and conservative AI analysis so you can avoid obvious IP mistakes before listing.
Known brands
Famous IP safety net
A curated blocklist of well-known brands and franchises flags high-risk terms even when a casual search might miss the context.
Risk levels
High, medium, low, or none
Color-coded risk cards with plain-language recommendations help you decide whether to revise a title or proceed with manual verification.
AI summary
Context for non-lawyers
A short analysis explains why a term might be risky for a KDP listing, conservative by design, erring toward caution.
EUIPO guidance
Advisory panel with verify links
EUIPO status is inferred for guidance only, not a live EUIPO API search. Official EUIPO links are provided for your own verification.
Account protection
Check before you commit
Screening distinctive title words early helps avoid takedowns and account issues caused by obvious trademark conflicts.
Clear go/no-go signals
One term, one decision at a time.
The results panel combines USPTO findings, risk scoring, and official links in one view, so you know what to verify before the listing goes live.
- Single-term search with instant results
- USPTO match details when registrations exist
- Overall risk level with recommendation text
- Links to USPTO TESS and EUIPO eSearch
Built for different publishers
One checker. Different risk moments.
Use the same workflow when naming a debut book, testing a series word, or sanity-checking a subtitle phrase.
New KDP publishers
Avoid obvious IP mistakes
Learn which title words trigger high risk before you upload, especially franchise, sports, and celebrity-adjacent terms.
Puzzle book catalogs
Screen themed title words
Check distinctive theme words, character names, and brand-like phrases before they appear on a cover or in backend keywords.
Series teams
Validate naming early
Test a series name or recurring subtitle word once, then document the result before rolling it across multiple ASINs.
Trademark Checker vs guessing
A quick screen beats publishing blind.
This tool combines USPTO API data and conservative AI guidance, it is not legal advice and does not replace a trademark attorney for complex cases.

KDP trademark screening guide
How to check title words responsibly.
A practical sequence for when to search, how to read risk levels, and what official verification still requires.
1. Check during research, not after upload
Run the checker while you are still choosing between title options. It is much cheaper to rename a draft book than to fight a takedown after publication.
2. Search one distinctive term at a time
Each run accepts a single term. Test the most distinctive word in your planned title, brand names, character names, sports leagues, or franchise-adjacent words, rather than the entire title string at once.
3. Treat high and medium risk seriously
High risk usually means live USPTO activity, a known-brand match, or conservative AI flagging. Medium risk warrants revision or deeper manual research. Low and none are encouraging but still require your own judgment.
4. Verify EU rights separately
The EUIPO panel provides advisory guidance and official links, it is not a live EUIPO database search. If you sell in European marketplaces, confirm status at euipo.europa.eu yourself.
5. This is not legal advice
RodBooks helps you screen obvious conflicts quickly. It does not replace a trademark attorney, comprehensive clearance search, or Amazon’s final enforcement decisions. Document your checks and avoid terms you cannot defend.
Frequently asked questions
Before you publish on KDP.
Clear answers about USPTO search, EUIPO guidance, risk levels, and what this tool does not guarantee.
Does it search the USPTO database?
Yes. Each check queries the USPTO trademark search API for live registrations matching your term and shows match details when available.
Does it search EUIPO live?
No. EUIPO guidance in the app is advisory. Use the provided EUIPO eSearch link to verify European trademark status yourself.
Can I check multiple keywords at once?
No. Each search checks one term at a time. Run separate checks for each distinctive word you want to evaluate.
What do the risk levels mean?
High, medium, low, and none summarize combined USPTO results, known-brand matches, and AI analysis. They are guidance for KDP publishers, not legal determinations.
Is this legal advice?
No. The tool helps you screen obvious conflicts quickly. Consult a trademark attorney for formal clearance, especially for brand-heavy titles or international publishing.
When should I run a check?
During Step 2 research, before you finalize titles, series names, or distinctive subtitle phrases. Pair it with the Title Generator once you have shortlisted options.
Does a low-risk result guarantee safety?
No. Always verify through official databases and use your judgment. Amazon enforcement and common-law rights can still affect listings beyond what an automated screen shows.
One distinctive word checked beats a takedown later.
Screen your title terms against USPTO data, read the risk signal, and verify officially before the listing goes live.
