Two Respiratory Therapists' Companies Collided Over a Shared Name

The situation

Jing's parents were both respiratory therapists before they were business owners. They met working in a hospital, and after years of watching patients struggle to source and maintain home oxygen equipment and CPAP machines, they started a small supply company in Niagara Falls to fill that gap. The name they chose reflected their own clinical background, something that sounded credible to physicians making referrals and to patients who were often frightened and confused about equipment they had never used before. Over almost thirty years, that name became something people in the local medical community recognized and trusted. When Jing's parents retired, Jing took over as the second-generation owner, alongside her sister Mei, who managed the clinical side of the business, running a company that by then brought in several million dollars a year supplying and servicing respiratory equipment across the region.

Jing had grown up around the business and understood, better than most owners in her position, how much of its value sat in that name. Physicians did not need to research the company before referring a patient because the name itself carried a history of reliability. Insurers processed claims faster because staff recognized it. None of that could be rebuilt quickly if the name ever became unreliable as a signal, which is exactly what started to happen when a new company registered in the same region under a name close enough to Jing's that referral staff at two different clinics sent patients to the wrong business within the same month.

The new company was run by someone named Ji-ho, who had also trained clinically before moving into equipment supply, and who, as far as Jing could tell, had not deliberately copied the name so much as landed on something similar by coincidence, drawing on the same kind of clinical, trustworthy-sounding naming convention that Jing's parents had used decades earlier. That did not make the confusion any less real. Patients calling for service appointments reached the wrong company. A referral fax intended for Jing's business arrived at Ji-ho's office instead, delaying a patient's equipment setup by several days.

Jing wanted the confusion to stop, but she also remembered her parents' approach to disputes in the small, tightly connected world of regional medical suppliers, which was to resolve things without burning bridges wherever that was possible, because the same referring physicians and the same industry contacts tended to remain relevant for years.

The legal problem

In Ontario, a corporate name does not need to be identical to another company's name to cause a legal problem. What matters is whether the names are similar enough to be confusing to the public, particularly when both companies operate in the same industry and the same geographic area, which was squarely the case here. Ontario's corporate registry does not automatically screen out every name that might cause confusion at the point of incorporation, which means two legitimately registered companies can end up with names close enough to create exactly the kind of mix-up Jing was experiencing, without either company having done anything obviously wrong at the outset. Confusion of this kind is not judged by setting two names side by side and studying them. It is judged on first impression, through the eyes of an ordinary customer in a hurry with only an imperfect memory of the other business's name, a lower bar than a careful side-by-side comparison would be. Sound, appearance and the ideas the names suggest all count, and the risk climbs when both businesses operate in the same industry and the same regional market, exactly the overlap Jing and Ji-ho shared.

Jing had two broad paths available. One was to pursue the matter formally, through a court claim for passing off or an application to require Ji-ho's company to change a name that was confusing to the public, on the basis that the newer name was likely to cause confusion with an existing, established business operating in the same sector. The other was to raise the concern directly with Ji-ho and try to resolve it by agreement, which is generally faster, less expensive, and less likely to damage a working relationship between two businesses that would keep encountering each other professionally regardless of how the dispute ended.

The complication was that Jing did not know, at the outset, how Ji-ho would respond. Going to court over a name dispute, whether by suing for passing off or seeking an order requiring a confusingly similar corporate name to be changed, was available but could take months, guaranteed nothing, and carried real cost and real time, for a company that ultimately just wanted the confusion to stop, not a prolonged fight. Passing off, at common law, generally requires proving that a business has built goodwill attached to its name, that the other company's use of a similar name misrepresents some connection between the two, and that the misrepresentation has caused or is likely to cause real damage. Jing likely had a case on all three, but proving it would have taken longer than the direct conversation tried first.

Jing's instinct, and ours, was to try direct resolution first, while keeping the option of going to court available as a fallback if Ji-ho was not willing to engage seriously.

What we did

1. Documented the specific instances of confusion that had already occurred, including the misdirected referral fax and the two clinics that had called the wrong company, because concrete examples carry far more weight in a negotiation than a general claim that two names sound alike, and because a court claim, if it became necessary, would need that same evidence to succeed.
2. Reviewed the corporate registry history of both names to establish clearly which company had registered first and how long each had been operating under its current name, since priority in time is one of the factors that matters both in a negotiation over who should be the one to change and in how a court would eventually weigh the dispute if it came to that, though priority alone would not decide the matter, since a court also looks at how distinct the names actually are once the confusion itself is documented.
3. Sent a measured letter to Ji-ho laying out the history of Jing's company's name, the documented confusion, and a request to discuss a resolution, deliberately framed as an invitation to talk rather than a threat, since the goal was a working relationship afterward, not a courtroom win that would linger over future referrals. The letter avoided legal threats or artificial deadlines designed to provoke a defensive reaction, on the view that a company approached respectfully is more likely to engage seriously than one that feels cornered from the first contact.
4. Prepared, but did not immediately issue, a passing-off claim, so that Jing had a credible fallback ready if the direct approach failed, and so Ji-ho understood the request was serious without the conversation opening as a legal fight neither company particularly wanted. Having the claim drafted and ready, rather than merely threatened, meant Jing could move quickly if negotiations stalled, without losing the months it typically takes to bring a claim like that before a court once it is actually issued.
5. Met with Ji-ho's lawyer once retained, and initially found the other side reluctant to change anything, arguing their registration was valid and that any confusion was a minor and temporary problem that did not justify the cost of rebranding signage, packaging, and referral paperwork. That position was not unreasonable on its face, since a validly registered name is not automatically wrong just because someone objects to it, so the early conversations made little visible progress.
6. Adjusted the proposal after Ji-ho's position shifted partway through the discussions, once their own referral partners began flagging the same confusion independently, giving Ji-ho their own practical reason to want a fix rather than relying solely on Jing's complaint as the sole source of pressure. Once Ji-ho's own clinics started asking why referrals kept going astray, the calculus changed from defending a registration on principle to solving a problem that was now costing Ji-ho business too.
7. Negotiated a specific, low-cost distinguishing change rather than a full rebrand, proposing that Ji-ho add a single distinguishing word to their existing name, which preserved most of their own brand investment while meaningfully reducing the overlap with Jing's company in the eyes of anyone reading it quickly. A full rebrand would have cost Ji-ho far more and given Jing little additional benefit, so the smaller change was the outcome that actually served both sides rather than one that simply declared a winner.
8. Confirmed the revised name did not itself infringe on any other registered business before the agreement was finalized, and documented the agreed change in writing with a clear timeline, so both sides had an enforceable record of what had been promised and by when. Skipping that last check would have risked solving one naming conflict only to create another, and a verbal understanding without a written timeline tends to drift once the people who negotiated it move on to other priorities.

The outcome

Ji-ho's company added a distinguishing word to its name, filed the corresponding amendment with the corporate registry, and updated its signage, website, and referral materials over the following two months. Jing's company kept its original name unchanged, and Mei, who dealt directly with the clinics on the clinical side of the business, reported that referral staff noticed the difference within weeks of the new signage going up. Neither side had to go through a court proceeding, and the direct cost to Jing was limited to the negotiation itself rather than a drawn-out dispute stretching over many months.

The compromise was not a clean win for Jing in the sense of forcing Ji-ho out of the market or securing any payment for the confusion that had already occurred. Two clinics had sent business to the wrong company for a period of weeks, and that could not be undone, and the affected patients were never compensated for the delay in their equipment setup. What Jing gained was confidence that the confusion would stop going forward, achieved without the delay, expense, or professional fallout that litigation could have produced in a regional industry where the same referring physicians and suppliers deal with each other for years and remember how a dispute was handled.

Six months later, Jing reported no further instances of misdirected referrals or confused patients. The relationship between the two companies remained professional, with both continuing to appear at the same regional supplier events without friction. Jing's parents, when told how it had resolved, said it was the outcome they would have pushed for themselves, since a formal fight would have cost more than the confusion itself and would have outlasted the goodwill both companies still needed from the same small circle of referring clinics.
