Another Company Has the Same Name as Mine: What to Do
Another company has the same name as mine: what trademark law covers, how search and AI answers confuse the two, and when to rebrand or stay.
If another company has the same name as yours, sharing a name is usually not unlawful by itself. The law cares about confusion: whether customers are likely to think the two businesses are connected, in the same field and the same territory. Search engines and AI assistants care about something different, which is whether they can tell the two apart.
You can be in the clear legally and still lose customers because the other company's reviews and listings sit above yours. This article separates the two questions and gives a decision rule for the hardest call: keep the name and differentiate, or rebrand.
Rules vary by country, and an office page is not a ruling on your facts. Your own counsel decides what applies to you, especially before you send a letter or change a registered name. This guide is information, not legal advice.
- Two companies can share a name when their goods or services are unrelated or their territories differ. Confusion, not identical spelling, is the legal test in most systems.
- Registering a company or business name is not the same as owning a trademark. The two are handled by different offices and give different rights.
- Reputation is a separate asset from legal rights. Search results and AI answers tend to follow clear, consistent, verifiable signals about who you are, not who registered first.
- Differentiate first with accurate, honest signals. Rebrand when the other party has stronger rights in your field, or when misdirected customers keep costing you after a fair trial period.
- Never imitate the other company, buy confusion, or hide the difference. That turns your problem into theirs.
Sharing a name is lawful until it confuses customers
Most trademark systems ask whether customers are likely to believe that goods or services come from the same source. The United States Patent and Trademark Office (USPTO) describes this as likelihood of confusion and calls it the most common reason for refusing registration. Marks do not have to be identical. They can be similar in sound, appearance or meaning, or give a similar commercial impression.
The second half of the test is relatedness. The USPTO page explains that identical marks owned by different parties can coexist when the goods or services are unrelated, and it uses a soap brand and an ice cream brand as its example. Goods can be related because they compete, are used by the same purchasers, are advertised together or are sold by the same manufacturer or dealer.

Territory matters as much as field. The World Intellectual Property Organization (WIPO) describes trademark protection as obtained through the office of each country or region, either by filing separately or through the Madrid System. IP Australia says an Australian trade mark protects only in Australia. In the United States, the USPTO says rights arise from using the mark with your goods or services but are limited to the area where you provide them, while federal registration gives nationwide rights.
A company name is not a trademark
Registering a company, LLC or business name does not make you the owner of the name as a brand. Companies House, the UK registrar, says company registration and trade marks are two different forms of protection administered by two different organizations. It adds that incorporating a company stops others registering the same or a very similar company name, but does not stop them trading under that name, and it calls the opposite belief a common misconception.
IP Australia makes the same point for business names: registering a business name does not give exclusive rights to it. The USPTO says it registers trademarks but does not enforce them, so enforcement is the owner's job, and it describes trademarks and domain names as registered with different bodies for different purposes.
The table below compares where rights come from in four systems. Each row is information drawn from official pages read for this guide, not legal advice and not a full statement of that jurisdiction's law.

Reputation and legal rights are two separate assets
Legal rights answer who may use a name for what. Reputation answers what people and machines believe the name stands for. They move independently.
Take a scenario with invented parties. A small firm called Larkfield sells bookkeeping software. A restaurant group also called Larkfield opens in the same region. The fields are unrelated, so a trademark claim is unlikely to be useful. But the restaurant group has many reviews and local news coverage, so searches for the shared name show restaurant results first. The software firm has no legal problem and a clear visibility problem.
Reverse the facts: if the restaurant group later adds a software ordering product under the same name, there is now a legal question, and its greater reputation does not settle it.
Diagnose legal exposure first, because it can force action, then visibility, which you can improve most directly.
Who was there first matters in more than one way
In the UK, section 69 of the Companies Act 2006 lets a person object to the registered name of a company formed and registered under that Act where the name is the same as one associated with the objector, in which they have goodwill, or sufficiently similar that its use would likely mislead the public into thinking the two are connected. Goodwill is defined to include reputation of any description. The respondent can raise four defences: the name was registered before the objector's activities began, it was registered in the ordinary course of a company formation business, it was adopted in good faith, or the objector's interests are not adversely affected to any significant extent. If the first or second is made out, the objection still succeeds where the name was registered mainly to extract money from the objector or to stop them registering it. The outcome depends on the facts.

It also said that a challenge to the applicant's trade mark belongs in a cancellation action at the Intellectual Property Office. It shows how one UK route works, not how your case will end.
First, work out whether you have a legal problem or a visibility problem
Answer five questions from records, not memory.
- Does the other company sell something related to what you sell, to the same type of buyer?
- Do the territories overlap? Check where each of you trades, ships or advertises, and where each has registered rights.
- Who started trading under the name first, and who filed first? These are different dates.
- Have customers, suppliers or press mixed up the two companies in a way you can document?
- Is the confusion a one-off, or does it recur in sales, support or hiring?
Search the official registers before you assume anything. The USPTO and IP Australia both direct applicants to search existing marks, and IP Australia's search covers registered and pending marks by word, phrase, image and owner. IP Australia notes that a trade marks attorney or lawyer can search for prior registered or unregistered marks, which points to the limit of a self-service register search: treat it as a starting point, not a clearance opinion.
| Situation | Legal problem? | Visibility problem? | First move |
|---|---|---|---|
| Different field, different region, no mix-ups | Unlikely | Possible | Differentiate in search; keep records |
| Different field, same region, occasional mix-ups | Possible if confusion grows | Yes | Document mix-ups; differentiate; consider counsel |
| Same field, overlapping territory, they filed first | Yes, and it may point to you | Yes | Counsel before any outreach or expansion |
| Same field, overlapping territory, you were first | You may have the stronger position | Yes | Counsel; gather proof of earlier trading and goodwill |
| Other company uses your exact name to look like you | Likely | Yes | Evidence file; counsel; platform reports where the rules fit |
Search engines and AI assistants see two companies as one name, not two entities
When two companies share a name, the query "larkfield" is ambiguous, and ranking reflects whichever pages have the strongest signals for that word: links, reviews, news coverage and listings. The larger or older entity often wins the head query; the smaller one has a better chance when the searcher adds a qualifier such as a city or a product.
AI assistants and AI search features add a second kind of error. They assemble answers from sources they retrieve or learned from, and when two entities share a name and the sources are thin or inconsistent, details can blend. A funding fact, a lawsuit or a review score from one company can appear under the other. What AI assistants say about you follows the same principle: assistants resolve a name to an entity, and the clearer your entity signals, the less room there is for a mix-up.
Related readLegal Dispute and Brand Reputation: A Company PlaybookTwo kinds of signal help, and neither is a trick.
Signals you control on your own site
Google's Organization structured data documentation recommends properties such as legalName, url, sameAs and logo. It says the url helps Google uniquely identify your organization, that identifiers such as iso6523 and naics are used behind the scenes to disambiguate it from others, and that vatID is a trust signal. sameAs lists other pages about your organization, and logo can affect which logo appears in search results and knowledge panels. The schema.org vocabulary separately defines disambiguatingDescription for text that distinguishes an item from similar ones; Google's page does not list it, so treat it as optional.
Google's site names documentation says site names draw on the home page and references on the web, that WebSite structured data is the most important way to state a preference, and that alternateName suggests a shorter variant. Use these to state your name the same way everywhere you control it.
None of this promises a ranking or a corrected AI answer. It reduces the ambiguity behind the mix-up.
Signals other people hold about you
Identity evidence also lives off your site: registry entries, a verified Business Profile, press mentions, directories and consistent profiles. Google's Business Profile guidelines say the name should reflect your real-world name as used consistently on your storefront and website, and that unnecessary information such as taglines or location details is not permitted in it. The guidelines also exclude product or service descriptions from the name field, so put what you do in the fields built for it, not in a decorated profile name.

Differentiation means making the true difference between the two companies easy to find. It never means resembling the other company or implying a connection that does not exist.
- Pick one public form of your name and use it everywhere. Use it on your site title, social profiles, invoices, directories and press kit, with a short line on what you do beside it where the format allows. Consistency lets machines match the dots.
- Own your branded page one with accurate pages. A clear home page, an about page that states who you are, where you operate and what you do, a team page where appropriate, and a contact page. Our suppression work follows the same logic: better, accurate, well-built pages outrank weaker ones.
- Mark up your entity. Organization structured data with legalName, url and sameAs, plus a disambiguating description if you choose; WebSite structured data with name and alternateName on the home page.
- Claim and complete the profiles that matter. Business Profile where you meet the eligibility rules, registry entries, industry directories, and the review sites your customers use. Each should show the same name and the same account of what you do.
- Add a short, neutral disambiguation line where it helps. On your about or contact page, a sentence such as "We are not affiliated with other organizations of the same name" is honest, short and helpful to customers who arrive by mistake. Do not name the other company.
- Log misdirected contacts. Record wrong-company emails, calls and reviews. The log becomes evidence if you later need counsel.
What not to do
Do not buy domains or profiles that look like the other company's, post reviews or comments about either company under invented identities, write content that attacks the other company, or add their brand terms to your own names. These break platform rules or create the confusion a court would care about.
A realistic 90-day plan for a same-name search problem
Visible movement in branded results usually takes weeks, and longer against a much larger company. Treat this as a typical sequence, not a promise.
- Days 1 to 7: baselineSearch your name in several search engines and ask three or four AI assistants who you are. Save dated screenshots and count misdirected contacts from the last 90 days.
- Days 8 to 21: legal screenSearch the trademark registers for your territory and field. Note filing dates, owners and goods or services. If fields and territories overlap, consult counsel before changing anything.
- Days 22 to 45: fix your own entityStandardize the public form of your name, publish the about and contact pages, add Organization and WebSite markup, and align profiles and directories.
- Days 46 to 70: earn third-party signalsAsk real customers for reviews on the platforms you already use. Pursue accurate coverage and directory listings where natural.
- Days 71 to 90: measure and decideRepeat the baseline searches and assistant questions. Compare misdirected contacts. Decide whether to continue, escalate legally or move toward a rebrand using the rule in the next section.
If the other company has a bad reputation, accurate separation is the goal, not attack: say clearly who you are, who you serve and where. If a platform or AI assistant states wrong facts about you because it merged the two, send a correction request with evidence.
When to rebrand and when to keep the name
Rebrand when keeping the name carries a legal or commercial cost that differentiation cannot reduce. Keep it when the harm is manageable and the equity in your name is real. The decision turns on five factors, taken together.
| Factor | Points toward keeping the name | Points toward rebranding | Evidence to gather |
|---|---|---|---|
| Legal position | You were first, or the fields and territories do not overlap | They hold earlier rights in your field and territory | Register search, dated proof of first use |
| Overlap of customers | Different buyers, different channels | Same buyers, same keywords, same marketplaces | Customer and sales channel list |
| Misdirected contacts | Rare and declining after your fixes | Regular and not improving after about 90 days | Contact log, review mix-ups |
| Search and AI visibility | You appear for the name plus a qualifier, assistants separate you | Assistants keep merging you after consistent signals | Dated search and assistant checks |
| Cost to switch | Heavy: many customers, contracts, domains and signage | Light: early stage, few assets tied to the name | Estimate for domains, legal, signage, relaunch |
A simple decision rule follows from the table. If the legal position points against you in your field and territory, treat rebranding as the default and get counsel's view on timing. If the legal position is neutral or favorable, run the 90-day plan, then rebrand only if misdirected contacts and merged answers persist and the cost to switch is lower than the ongoing loss. A company with a few months of history has little to lose by renaming early. An established firm carries reviews, links and recognition under the name, so it has a stronger case for differentiation first.

Plan a rebrand like any migration. Keep the old domain redirecting, update registry entries, profiles and structured data with a note of the former name, and tell customers directly. Check the new name against the trademark registers in each territory before you commit. A new name that collides with a third party only moves the problem.
Formal routes and how to approach the other company
Before any formal step, gather dated proof of first use, registrations, examples of confusion and your contact log. Do not start with a cease-and-desist letter: one that overstates your rights can weaken your position.
The routes below are the ones the official sources read for this guide describe. They are not a complete list.
- Direct, friendly contact. The EUIPO opposition page notes that an applicant may contact the opponent to propose a solution, and the process includes a cooling-off period for an amicable settlement. The same logic works before any filing: a short written agreement on fields, territories and how each describes itself can settle a same-name situation.
- Opposition to an application. In the European Union, the owner of an earlier right can oppose an EU trade mark application no later than 3 months after publication, and the EUIPO page describes a fee, a cooling-off period and a decision on whether the application is rejected in whole or in part. Other offices have their own systems and time limits.
- Company name objection in the UK. Section 69 of the Companies Act 2006, described above, applies to a company's registered name and depends on goodwill and likelihood of misleading the public. It does not decide trade mark validity.
- Domain name disputes. The WIPO Uniform Domain Name Dispute Resolution Policy requires a complainant to show that the domain is identical or confusingly similar to a mark in which it has rights, that the registrant has no rights or legitimate interests, and that the domain was registered and is used in bad faith. This route is for abusive registrations, not ordinary same-name overlap.
- Court action. In the United States, 15 U.S.C. 1125(a)(1) creates civil liability for using a word, name or symbol in commerce in a way likely to cause confusion. In the UK, passing off requires goodwill, misrepresentation and damage, as the nibusinessinfo.co.uk guidance on passing off sets out. Both are for counsel to assess.
If you might be the one infringing, the same sources apply in reverse: do not expand into their field or territory until counsel has reviewed the risk.
The next step: take a dated baseline before you decide
A dated baseline of what search engines and AI assistants say about you supports the legal screen, the differentiation plan and any rebrand decision.
If customers, reviewers or AI assistants are already mixing you up with another company, capture the evidence this week and ask for a private review of how both names appear. Reputation Partners can run that audit and tell you whether the problem is legal, visibility or both. Request a private audit.
Questions people ask
Can two companies have the same name?
Yes, in many cases. Trademark systems usually test for likely confusion among related goods or services in a given territory, so two unrelated businesses in different places can share a name lawfully. The risk rises when fields, customers and territories overlap, so check the registers that apply to you.
Does registering my company name give me the exclusive right to use it?
Usually not by itself. Companies House says company registration and trade marks are separate protections, and that incorporating stops another identical or very similar company name being registered but not trading under it. IP Australia says business name registration gives no exclusive rights. A registered trade mark in your field and territory is the stronger tool.
What if the other company is in another country?
Trademark protection is generally territorial, so a mark registered in one country does not by itself protect you in another. WIPO describes protection as obtained through each country's or region's office. If either of you sells online across borders, or plans to expand, the overlap can still matter, so check the registers where you operate or plan to.
Why does an AI assistant mix up my company with the other one?
Assistants must decide which entity a question refers to, and thin or inconsistent sources make that harder. Clear signals help: one public form of your name, structured data, matching profiles and independent mentions. They reduce the chance of a mix-up but cannot remove it.
Should I send a cease-and-desist letter?
Not as a first step. Gather evidence, check the registers and speak to counsel who knows the trademark law of your country. A letter that overstates your rights can provoke a counterclaim or public attention. If your position is strong, counsel may still suggest a friendly approach before any formal demand.
Is the other company's bad press my problem?
It becomes your problem when readers or assistants attribute it to you. Do not attack the other company. Make your identity clear, correct wrong attribution with evidence, and build accurate pages for your name plus your descriptor. If the confusion persists and costs you customers, weigh it in the rebrand decision.
