  • Can You Use Another Company’s Name or Logo?

    Can You Use Another Company’s Name or Logo?

    You may sometimes use another company’s name or logo, but permission depends on why and how you use it. Referring to a brand to identify genuine goods, describe compatibility, compare products, report news, or comment may be lawful. Use that suggests sponsorship, affiliation, or your own product source creates greater risk.

    Names and word marks are often easier to reference accurately than logos and trade dress. Use only what is reasonably necessary and make your own branding clear.

    Trademark law focuses on source and confusion

    Trademark infringement generally requires likely consumer confusion about source, sponsorship, or affiliation. Federal law also addresses false or misleading representations. See 15 U.S.C. § 1125(a).

    Presentation, context, and the amount of another brand’s material used can affect risk.

    Common situations where reference may be permissible

    Compatibility and repair services

    A seller may need to state that a replacement part fits a particular branded product or that a repair shop services certain brands. The statement should be accurate and should not imply authorization. Prominent independent branding and a clear relationship statement may help.

    Resale of genuine goods

    Resellers can often identify genuine trademarked products they lawfully sell. Materially altered goods, removed quality controls, misleading repackaging, gray-market differences, or a presentation implying an authorized dealership can create additional issues.

    Comparative advertising

    Truthful comparison may identify a competitor. The Federal Trade Commission encourages truthful, nondeceptive comparative advertising and expects objective claims to be substantiated. Review the FTC’s comparative advertising policy.

    Commentary, reviews, parody, and news

    The First Amendment and trademark doctrines can protect expressive reference, but context matters. In Jack Daniel’s Properties, Inc. v. VIP Products LLC, the Supreme Court held that ordinary trademark analysis applies when the challenged designation is used as a source identifier for the defendant’s own goods.

    Important qualification: Courts use different approaches to nominative fair use and expressive works. Do not treat a single three-part internet test as nationwide law.

    Descriptive fair use

    Federal law recognizes a defense for certain good-faith descriptive uses of words otherwise registered as marks, when the term is used descriptively rather than as a trademark. The statutory language appears in 15 U.S.C. § 1115(b)(4). This defense does not authorize misleading source claims.

    Why logos often present more risk

    A logo may communicate affiliation more strongly than a plain-text reference and may also be protected by copyright. Copying a logo, product image, packaging, or website design can therefore raise several legal issues. Use a word reference when it adequately conveys the necessary information.

    Risk-reduction checklist

    • Make the statement truthful, specific, and supportable
    • Use only the amount of the mark needed for the purpose
    • Avoid another company’s stylization, logo, packaging, or trade dress unless necessary and justified
    • Make your own brand more prominent
    • Do not call yourself authorized, certified, official, or partnered without permission
    • Review platform advertising and marketplace rules in addition to trademark law
    • Obtain permission for campaigns where the relationship itself is part of the message

    A disclaimer can clarify a relationship, but wording cannot cure an overall presentation that is confusing. Evaluate the entire page, advertisement, packaging, or product.

    Read next: the practical elements of trademark infringement.

    The practical next step

    Before launch, save the proposed use in context and identify the business reason for using the mark. Counsel can assess confusion, fair use, copyright, advertising claims, and circuit-specific rules without reviewing the reference in isolation.

  • How to Handle Trademark Complaints on Amazon and Etsy

    How to Handle Trademark Complaints on Amazon and Etsy

    Amazon and Etsy allow trademark owners or authorized agents to report allegedly infringing content. A useful report identifies the trademark right, the exact listing or content, and why the particular use infringes. Platform removal is an administrative action, not a court ruling on the merits.

    Sellers receiving a complaint should preserve the notice and listing, verify the asserted right, identify the complainant, and use the platform’s response or appeal process accurately.

    Before filing any marketplace report

    1. Confirm that you own or are authorized to enforce the trademark.
    2. Verify the registration number, owner, status, territory, and covered goods or services.
    3. Capture the exact listing, seller offer, images, title, and challenged language.
    4. Distinguish counterfeit branding from resale, compatibility language, comparative reference, or another potentially lawful use.
    5. State only facts you can support.

    Reports should identify the exact branding and listing content being challenged.

    Reporting a trademark issue to Amazon

    Amazon provides tools through Brand Registry and a public Report Infringement form. Amazon asks reporters to identify the intellectual property, the nature of the complaint, and the content involved. Its guidance distinguishes an ASIN, an individual seller offer, and product-detail-page content.

    Choose the target carefully. Reporting an entire ASIN when the concern is one seller’s offer can affect unrelated sellers. Amazon’s Report a Violation guidance also explains Brand Registry tools and retractions.

    Reporting a trademark issue to Etsy

    Etsy directs rights owners and authorized agents to its Reporting Portal. The reporter adds the intellectual property and identifies specific listings. Etsy states that it may share the reporter’s name and email address with the affected member.

    Etsy also explains that it does not decide complex legal merits and may disable reported content under its policy. Its Intellectual Property Policy warns against abusive or bad-faith reports.

    Common mistake: Do not report a listing merely because it contains your brand name. The use may identify genuine goods, describe compatibility, compare products, or refer to the brand in another context. Evaluate the full listing and applicable law.

    If your listing was removed

    1. Save the complete platform notice and the listing as it appeared before removal.
    2. Verify the registration and complainant information.
    3. Identify whether the complaint targets the product, seller offer, images, title, tags, or description.
    4. Review invoices, authorization, product authenticity, and how the trademark was used.
    5. Use the stated appeal or contact process; avoid unsupported counter-allegations.
    6. Consider counsel if inventory, account health, repeated complaints, or a broader dispute is at stake.

    Platform action does not settle the legal dispute

    A removal may reflect platform policy and risk management. It does not necessarily establish infringement, priority, damages, or a defense. Conversely, a rejected report does not establish that the use is lawful.

    Read next: what trademark infringement requires.

    The practical next step

    Prepare a short evidence packet containing the registration record, chain of ownership, screenshots, listing identifiers, seller details, and a precise explanation of the challenged use. Accuracy and narrow targeting reduce avoidable collateral harm.

  • Who Has Priority in a Trademark Dispute?

    Who Has Priority in a Trademark Dispute?

    Trademark priority generally favors the party that first established protectable rights for the relevant goods or services. Actual use can create common-law priority. A qualifying federal application may also provide a constructive-use priority date if it later registers. Geography, application basis, foreign priority, and earlier users can change the result.

    Priority is not simply who thought of the name first

    Private brainstorming, domain registration, an LLC filing, or reserving a social handle usually does not establish trademark priority by itself. Trademark rights ordinarily require qualifying use or a statutory filing path that matures into enforceable rights.

    Priority evidence should connect the mark to actual marketplace goods or services.

    Common-law priority from use

    A business may acquire rights through actual use of a distinctive mark in commerce, even without federal registration. Those rights can be limited by the territory and market penetration established through use and reputation.

    Useful evidence may include dated invoices, sales records, shipment records, advertisements tied to actual services, website archives, packaging, catalogs, and testimony supported by business records. A claimed date without documentation may be difficult to prove.

    Constructive-use priority from a federal application

    Under 15 U.S.C. § 1057(c), filing an application to register on the Principal Register can create nationwide constructive use, contingent on registration. The statute preserves exceptions, including persons who used the mark before that filing and certain earlier applications or foreign-priority claims.

    An intent-to-use applicant therefore may obtain a priority date before commercial launch, but enforceable registration rights depend on completing the application and establishing use as required.

    Example: Assume Company A begins qualifying local use in Kentucky in January. Company B files a federal intent-to-use application in March and later registers. Company A may retain prior rights in its established area, while Company B may obtain broader constructive priority subject to the facts. This hypothetical is simplified.

    Foreign priority and other filing rules

    Certain applicants may claim priority based on a qualifying foreign application filed within six months. Madrid Protocol filings and related extensions can also affect dates. Confirm the application record and statutory basis instead of comparing only U.S. filing dates.

    Priority must match the relevant scope

    A party may be earlier for one product line, service, territory, or mark variation but not another. Ownership changes and assignments must also preserve the underlying goodwill. Priority analysis should identify the specific mark, goods or services, geography, and chain of title.

    How to build a priority record

    1. Create a chronology of selection, launch, sales, expansion, filings, and ownership changes.
    2. Collect original records showing the mark with the goods or services.
    3. Verify USPTO application and registration histories in TSDR.
    4. Identify geographic sales, customers, advertising reach, and revenue by period.
    5. Check for earlier third-party users and foreign-priority claims.

    The USPTO’s dates-of-use guidance explains how applicants report first use, but a claimed date in an application is not a substitute for proof in a dispute.

    The practical next step

    Build the evidence file before sending demands or committing to a contested application. Counsel can then analyze constructive priority, common-law territory, chain of title, and the governing forum’s rules.

  • What to Do After Receiving a Trademark Cease-and-Desist Letter

    What to Do After Receiving a Trademark Cease-and-Desist Letter

    A trademark cease-and-desist letter is a private demand, not a court judgment. Do not ignore it, but do not assume every allegation is correct. Preserve the letter and your business records, calendar any response date, and evaluate ownership, priority, confusion, defenses, and business options.

    Your early communications can affect later negotiations or litigation. A measured investigation is usually more useful than an immediate admission, denial, or public post.

    First steps after receiving the letter

    1. Save the letter, envelope, attachments, and transmission metadata.
    2. Calendar the requested response date and check for any separate court or agency deadline.
    3. Tell relevant employees not to delete or alter potentially relevant records.
    4. Preserve your first-use evidence, sales records, advertisements, packaging, websites, and customer communications.
    5. Avoid contacting the sender until you understand the facts and objectives.
    Documents and notebook arranged for reviewing a trademark demand letter.
    Organize the demand, deadlines, and evidence before choosing a response.

    Check what the sender actually claims

    Identify the asserted marks, registrations, goods or services, claimed first-use dates, geographic scope, accused uses, legal theories, and requested relief. Verify registration status in the USPTO’s TSDR system rather than relying only on the letter.

    A registration can be important, but its wording, owner, status, and covered goods or services matter. A registration does not automatically prohibit every use of the same word.

    Assess priority and likely confusion

    Compare each party’s dates and actual marketplace use. Then consider the marks as consumers encounter them, the relationship between the offerings, customer care, channels, geography, and confusion evidence. The governing factor test varies by federal circuit.

    Common mistake: Do not quietly redesign the website and discard the old version. Preserve the accused materials and their dates first. Changes may be sensible later, but the historical evidence may be important.

    Consider defenses and counterclaims

    Potential issues may include descriptive fair use, nominative reference, consent, license, abandonment, fraud allegations, priority, geographic limits, nonuse, or invalidity. Some defenses depend on precise wording and circuit law. A recipient may also have claims of its own.

    Response options

    • Request additional information or time
    • Explain why the claim is unsupported
    • Offer targeted changes without admitting liability
    • Negotiate a coexistence, phase-out, license, or settlement
    • Stop the challenged use when the risk and economics support that choice
    • Seek declaratory relief or defend litigation when necessary

    The best response depends on legal strength, rebranding cost, customer impact, insurance, public relations, and the sender’s apparent objective. Silence can prompt escalation, but a rushed substantive response can surrender useful positions.

    Watch for real legal deadlines

    A letter’s requested date is usually set by the sender. Court summonses, temporary restraining order papers, TTAB notices, and platform deadlines require separate attention and may carry legal consequences. Confirm what was received.

    Read next: what trademark infringement means.

    The practical next step

    Send counsel the complete letter, a chronology, registrations and applications, first-use evidence, current and historical branding, sales channels, and your business objective. That allows a faster assessment and a response tailored to the actual risk.

  • Someone Is Using My Business Name. What Should I Do?

    Someone Is Using My Business Name. What Should I Do?

    Start by documenting the other business’s use and checking your own trademark rights. Similar names can coexist when the businesses, customers, or geographic markets differ. A legal claim is stronger when you have priority and the later use is likely to confuse consumers.

    Do not begin with an angry public accusation. Preserve evidence, identify the correct party, and decide what business outcome you want.

    1. Preserve what you found

    Capture full-page screenshots showing the URL and date. Save product listings, packaging, social profiles, advertisements, marketplace pages, contact details, and evidence of where the business sells. Record any misdirected calls, emails, reviews, returns, or customer questions.

    Preserve dated marketplace evidence before contacting the other user.

    2. Confirm your own rights and priority

    Collect your first sales records, dated advertising, website archives, packaging, registrations, applications, and any assignments. A state entity registration or domain name alone does not establish nationwide trademark priority.

    Federal registration can provide significant benefits, but earlier common-law users may retain rights in areas where they established use. Read how trademark priority works.

    3. Evaluate likely confusion

    Compare the names as consumers encounter them, along with the parties’ goods, services, customers, prices, channels, and locations. Evidence of actual confusion can help, but it is not required. The governing legal test differs by jurisdiction.

    Practical tip: Search beyond Google. Check state business records, USPTO records, marketplace seller pages, social platforms, domain registration information where available, and archived website versions.

    4. Identify who controls the use

    The visible seller may be a franchisee, distributor, marketplace account, subsidiary, or individual using a trade name. Confirm the legal entity and contact information before sending a demand or filing a report.

    5. Choose a proportionate response

    • Monitor a remote or low-risk use while preserving evidence
    • Send a neutral inquiry seeking facts
    • Propose geographic, product, or presentation limits
    • Send a formal cease-and-desist letter
    • Use a marketplace or social-platform reporting process
    • File an opposition, cancellation, or federal court action when the facts and stakes justify it

    A platform complaint can remove content quickly, but an inaccurate report can create business and legal risk. Litigation can provide broader relief, but it is expensive and fact-intensive.

    Avoid common mistakes

    • Assuming an LLC filing creates nationwide trademark ownership
    • Demanding that every use of a shared word stop
    • Overstating registration scope or geographic rights
    • Deleting or altering evidence after the dispute begins
    • Threatening litigation before assessing defenses and counterclaims

    The USPTO registers marks but does not enforce private rights. Its infringement overview explains that owners are responsible for enforcement.

    The practical next step

    Prepare a one-page chronology, a folder of dated evidence, and a comparison of the parties’ actual offerings. Counsel can use that package to assess priority, confusion, defenses, and a response that fits the commercial objective.

  • What Is Trademark Infringement?

    What Is Trademark Infringement?

    Trademark infringement is generally unauthorized use of a mark in commerce that is likely to confuse consumers about the source, sponsorship, or affiliation of goods or services. Identical wording is not required. Courts examine the marks, products, customers, sales channels, evidence of confusion, and other circumstances.

    Owning a registration helps, but it does not make every similar use unlawful. The practical question is whether the challenged use interferes with the trademark’s source-identifying function.

    The core elements of an infringement claim

    A plaintiff usually must establish a protectable trademark right, priority over the defendant in the relevant market, and a likelihood of confusion. A federal registration can provide important procedural and evidentiary benefits. Earlier common-law use may still matter.

    The USPTO explains that likelihood of confusion is assessed under multiple factors and that the particular evidence controls. The exact factor test and weighting vary by federal circuit. See the USPTO’s infringement overview.

    The relevant market, customers, and sales channels affect the confusion analysis.

    Similarity is broader than an exact match

    Courts may compare appearance, sound, meaning, and overall commercial impression. Similarity matters more when the parties offer closely related products through the same channels. A shared ordinary word may receive less weight if the rest of each mark creates a different impression.

    Example: Assume one company uses NORTHSTAR for bookkeeping software and another later uses NORTH STAR LEDGERS for closely related cloud accounting services. The analysis would consider the marks as a whole, the related services, customers, channels, and evidence. This hypothetical does not mean either name is legally available.

    Evidence that often matters

    • How and when each party began using the mark
    • Registrations, applications, packaging, websites, advertisements, and sales records
    • The strength and marketplace recognition of the senior mark
    • Actual confusion, including misdirected communications or support requests
    • The defendant’s intent, where relevant under the governing circuit’s test
    • Differences in customers, price, purchasing care, geography, and sales channels

    Preserve original files, dates, URLs, screenshots, invoices, analytics, customer messages, and product samples. A dated evidence file is usually more useful than a later narrative reconstructed from memory.

    Defenses and lawful uses

    A defendant may dispute validity, ownership, priority, use in commerce, or likely confusion. Depending on the facts, descriptive fair use, nominative reference, consent, license, acquiescence, laches, or other defenses may apply. These doctrines are fact-specific and vary across jurisdictions.

    Possible remedies

    The Lanham Act authorizes remedies that may include injunctions, recovery of certain profits or damages, costs, destruction or disposition of infringing materials, and attorney fees in exceptional cases. The remedy depends on proof and equitable principles; it is not automatic. Review 15 U.S.C. § 1117 and 15 U.S.C. § 1118.

    What to do if you suspect infringement

    1. Confirm your ownership, priority, registration status, and current use.
    2. Capture the challenged use and identify who controls it.
    3. Assess confusion, defenses, business harm, and the desired outcome.
    4. Choose a proportionate response, such as monitoring, outreach, a coexistence discussion, a platform report, or litigation.
    5. Have counsel review the evidence before making accusations or threatening suit.

    Read next: what to do when someone is using your business name and how to respond to a trademark cease-and-desist letter.

    The practical next step

    Build a short chronology of both parties’ use and collect the actual marketplace materials. A trademark lawyer can then evaluate the governing circuit’s factors, potential defenses, and a response calibrated to the business risk.
