In a recent decision, the São Paulo Court of Justice (TJSP) dismissed a lawsuit brought by the owner of Hospital Santa Catarina in São Paulo against another healthcare institution operating under a similar name in the state of Santa Catarina.
Hospital Santa Catarina is a well-established medical facility in São Paulo, with a strong reputation built over the last decades for its services. The plaintiff alleged that the defendant was engaging in unfair competition by using the name “Hospital Santa Catarina,”.
Specifically, it was claimed that the similarity between the names could confuse consumers, dilute the plaintiff’s brand, and unfairly capitalize on its goodwill. The plaintiff sought damages and an injunction to prevent the defendant from using the name, arguing that this constituted a violation under the Brazilian Industrial Property Law and principles of unfair competition outlined in the country’s Civil Code.
The defendant countered that the hospitals operated in geographically distinct regions with no overlapping patient bases or marketing efforts. They also emphasized that the name “Santa Catarina” holds cultural and historical significance, particularly because the hospital is based in the homonymous state in the south of Brazil, named after Saint Catherine of Alexandria, and that their use of the name was not intended to mislead or exploit the plaintiff’s reputation.

Furthermore, the southern hospital pointed out that the plaintiff’s trademark registration was limited in scope and did not extend nationwide exclusivity, especially because of the descriptive nature of the name in that given context, that is, when the hospital’s name is also a state’s name.
After careful review, the court sided with the defendant, rejecting the unfair competition claim. The decision was centered on the lack of evidence showing intentional parasitism or actual consumer confusion. Judges noted that the hospitals’ services were confined to their respective locations, mitigating the risk of market overlap.
This rationale exemplifies the application of the trademark law by the courts in Brazil, ensuring that intellectual property rights are enforced without stifling legitimate business activities. Specially for investors, the outcome marks Brazil as a jurisdiction where trademarks are fairly protected, encouraging innovation and deterring frivolous litigation. Such stability is crucial for fostering a secure environment and welcoming new players into the Brazilian market.
