Before listing on Amazon, sellers should run infringement checks across trademarks, utility patents, design patents, and copyrights. This guide compiles 10 official lookups, including USPTO, WIPO, EUIPO, UK IPO, CNIPA, EPO, and the U.S. Copyright Office, and walks you through a workflow from keyword pre-screening to lawyer review.
An Amazon infringement check is not a matter of dropping a product name into a "sensitive-word tool" and calling it done. Trademarks protect brand identifiers, patents protect technical solutions, design rights protect product appearance, and copyrights protect images, copy, packaging artwork, and video. Each right has its own search logic, jurisdictions, and term.
Below are 10 official or authoritative public databases covering the United States, the European Union, the United Kingdom, China, and the international system. They are useful for pre-listing screening, validating complaint evidence, and saving search records, but a clean database result does not mean you are safe. For high-value products, lawyer letters, or large production runs, hire an IP attorney in the target market to run a full clearance and legal analysis.
First, Decide Which Right You Are Checking
| Right type | Common risk | Screening focus |
|---|---|---|
| Trademark | Using a third party's brand or a confusingly similar mark in title, bullet points, packaging, or images | Spelling, pronunciation, meaning, design, Nice class, status |
| Utility / design patent | Product structure, function, or method falling within someone else's claims | Independent claims, patent family, legal status, target jurisdictions |
| Design right | Similar look-and-feel in product shape, pattern, UI, or packaging | Overall visual impression, views, classification, applicant, term |
| Copyright | Reusing images, video, manuals, copy, illustrations, or software | Work origin, author / rights holder, creation and license chain |
The same product can touch all four. Take a branded smart desk lamp: its name may trigger trademark risk, its dimming mechanism may hit a utility patent, its body shape may be close to a registered design, and its hero images plus manual may be protected by copyright.
1. USPTO Trademark Search (United States)
Entry: USPTO Trademark Search
The USPTO Trademark Search covers U.S. federal trademark applications and registrations. Before listing on Amazon.com, search for at least:
- The exact brand word;
- Spaces, hyphens, singular / plural, and common spelling variants;
- Words with similar pronunciation or meaning;
- Records of the same keyword in related goods and services;
- Logo or figurative elements that look similar.
Do not stop at "is there an identical mark." Likelihood-of-confusion analysis also weighs relatedness of the goods, commercial impression, and similarity of the marks. The USPTO itself reminds users that database search is only one part of a complete clearance search.
2. WIPO Global Brand Database
Entry: WIPO Global Brand Database
The Global Brand Database covers Madrid-system international trademarks, Lisbon-system appellations of origin and geographical indications, selected national and regional trademark records, and official emblems. You can search by keyword, owner, number, goods and services, and image similarity.
It is great for global first-pass screening and international registration lookups. WIPO also points out that the global database does not include every live record from every country, so you should still check the official register of the target IP office.
3. TMview (EU and participating offices)
Entry: TMview
TMview is provided by the European Union Intellectual Property Network and unifies trademark data from EUIPO, EU member-state offices, and some non-EU participating offices. It works well for multi-jurisdiction first-pass screening for Amazon Europe.
Filter by text, owner, Nice class, and status. After you see results, go back to the originating office's official record to confirm current status, renewals, oppositions, and the goods and services scope. Don't rely on the aggregated view alone.
4. UK IPO Trade Mark Search (United Kingdom)
Entry: GOV.UK trademark search
After Brexit, trademark screening for Amazon.co.uk should look at the UK IPO on its own. The official entry supports search by number, owner, keyword, phrase, or image, and you can also browse the trademark journal.
Beyond the brand name, search product line names, the dominant packaging visual, and any phrase that could be read as a source indicator. If a record shows as historic, also weigh prior use, common-law rights, and other unregistered risk.
5. CNIPA National IP Public Service Platform (China)
Entry: CNIPA National IP Public Service Platform
Chinese sellers need to check both selling countries and the supply-chain country. The CNIPA platform provides trademark gazettes, examination decisions, registration certificates, patent publication gazettes, China and multinational patent data, and design image search.
It is the right place to verify a supplier's claim of "we own the patent" or "we have a brand license." Ask the supplier for application numbers, registration numbers, rights holders, and license documents, then verify them on the official system. Don't accept a cropped certificate image.
6. USPTO Patent Public Search (United States)
Entry: USPTO Patent Public Search
This tool covers U.S. patents and published applications. Basic Search supports keyword, inventor, and publication or patent number; Advanced Search adds fielded search with operators and finer filters.
For technology patents, marketing terms rarely work. Start from the core structure, component relationships, functional actions, and synonymous technical terms, then expand using CPC / IPC classification. When you find similar documents, read the independent claims carefully, not just the abstract or figures.
7. WIPO PATENTSCOPE (PCT and national collections)
Entry: WIPO PATENTSCOPE
PATENTSCOPE provides published PCT international applications plus the collections of participating national and regional offices. You can search by keyword, IPC, number, applicant, chemical structure, and it includes machine translation and multilingual tools.
It is especially useful for finding patent families and cross-border filing traces. A PCT application is not a "global patent" by itself. Whether a right has entered the national phase, been granted, lapsed, or is still alive must be checked against the official records of each country.
8. Espacenet (EPO global patent literature)
Entry: EPO Espacenet
Espacenet is run by the European Patent Office and covers a large share of global patent literature. It supports keyword, classification, applicant, inventor, citation, and patent-family search, and provides machine translation and Global Dossier information.
It is the right tool for expanding from one patent to its forward and backward citations, family members, and competitor filing patterns. EPO notes that legal-status information can indicate whether a right is granted and in force, but you should still verify against the target country's official register.
9. DesignView (EU and participating design offices)
Entry: DesignView
DesignView aggregates registered design data from EUIPO and participating national IP offices. It is especially useful for visually driven products: furniture, lighting, fashion accessories, consumer electronics housings, toys, packaging, and graphical user interfaces.
Don't search designs by product name only. Combine Locarno classification, applicant, views, and product category, and compare overall visual impression view by view. Similarity analysis is a legal discipline, and "it looks different" does not automatically remove the risk.
10. U.S. Copyright Public Records System
Entry: U.S. Copyright Public Records System (CPRS)
The U.S. Copyright Office's CPRS lets you look up copyright registrations and transfers. Use it to check images, illustrations, video, music, manuals, and other works by title, author, rights holder, or registration number.
Copyright generally arises when a work is created and fixed in a tangible medium, and not every work gets registered. "No record found" does not mean you can copy. Keep original camera files, design sources, commissioning contracts, license agreements, invoices, and scope-of-use records to prove your right to use the materials.

Pre-listing Infringement SOP
Step 1: Build the product right inventory
Break the product down into brand word, line name, logo, packaging, appearance, core structure, software UI, hero image, video, copy, and music. Record the source and license proof for each item.
Step 2: Lock the sales countries and time window
IP rights are territorial. Amazon.com, Amazon.co.uk, and EU stores need different registers. You also need to confirm the right is still alive across the planned sales period.
Step 3: Start with broad keyword screening
Search exact words, word stems, spelling and pronunciation variants, synonyms, product categories, and competitors. For patents, use structure and action terms, not just e-commerce titles.
Step 4: Expand by classification and rights holder
For trademarks, check Nice class and related goods. For patents, check CPC / IPC. For designs, check Locarno. Then look for family rights by applicant, inventor, designer, and related companies.
Step 5: Verify legal status and right scope
"A search result exists" does not mean infringement. "Showing as expired" does not mean all risk is gone. Verify application, grant, renewal, invalidation, abandonment, territory, and claims.
Step 6: Save the evidence
Save the search date, query string, filters, key record links, and supplier documents. Databases change; keeping the trail helps your team review and reply later.
Step 7: For high-risk items, get a professional review
When the product is structurally close to a prior patent, when the brand is a core asset, when the planned stock value is high, or when you have already received a complaint, ask a target-market lawyer for an opinion. A freedom-to-operate (FTO) analysis cannot be done with one keyword search.
Common Misconceptions
"No identical trademark means we are safe."
Wrong. Trademarks can conflict through similar pronunciation, meaning, appearance, or overall commercial impression, and related goods do not always sit in the same Nice class.
"Our supplier said they have a license, so we don't need to check."
A license can be limited to a specific country, channel, term, or designated store. You need to confirm the licensor really has authority to grant the license and that it allows Amazon use of the images, brand, and product.
"If the patent abstract is different, there is no infringement."
Infringement analysis usually centers on the valid claims, not the abstract. You need claim-by-claim technical feature comparison and must consider doctrines such as equivalents.
"Copyright only exists if the work is registered."
Wrong. In many jurisdictions copyright arises automatically when the work is created and fixed. Registration mainly serves as evidence and as part of enforcement procedures.
Managing Search Records Across Multiple Stores
For a team running multiple Amazon stores and brands at the same time, the trouble is rarely "don't know how to search" but "wrong record in the wrong place." Brand A's search screenshot is pasted into Brand B's complaint response, Brand A's sales authorization is quoted as Brand C's basis, and the legal entity in the screenshot doesn't match the store that's logged in. Each of these makes an already manageable case much harder to resolve.
A practical pattern is to set up a separate browser environment for every authorized Amazon store and write the store entity, target market, brand, license term, and search-archive location into the environment note or your team knowledge base. Each environment signs into its own Amazon Seller Central, brand mailbox, and trademark office account, so the saved screenshots, PDFs, and search records naturally belong to the right entity and don't get copy-pasted somewhere they shouldn't. This pattern handles work environment and record ownership. It does not decide whether a trademark, patent, or copyright is infringed, and it does not bypass the platform's IP review. When a complaint comes in, you still need to gather proof of rights, sourcing, and licenses, and respond through Amazon's official process.
FAQ
Are these sites free?
The public lookups listed here are usually free, but some advanced features, bulk data, certified copies, or professional analyses may charge a fee or require an account.
If I find a similar patent, do I have to delist?
Not necessarily. You need to confirm the patent's country, legal status, claims, and whether the technical features of your product actually map to them. Don't decide from the title or a figure alone.
Can cropping or color grading avoid copyright infringement?
No. Minor edits do not make unauthorized copying legal by themselves. Use originals, self-made assets, or materials with a clear license scope.
What should I do first after receiving an infringement complaint?
Stop any action that could expand the loss, save the complaint notice and the product page, check the complainant's rights, ASIN, license, and sourcing files, and then decide based on the evidence whether to appeal, negotiate, or delist. For important cases, talk to a lawyer quickly.
Closing
The right way to run an infringement search is to separate the right types first, then use the right official database for each sales country, and finally verify the legal status and scope. These 10 sites can substantially improve first-pass screening, but they cannot give you a "guaranteed safe" verdict.
Move the search upstream, into product selection, sampling, packaging, and pre-listing, and keep the full license trail. That costs far less than scrambling for evidence after a complaint.
