Porolis Technologies Pte Ltd (Porolis) today welcomed the decision of the Intellectual Property Office of Singapore (IPOS) dismissing an opposition by OpenAI, OpCo, LLC to its “GemGPT” trade mark application.

In OpenAI, OpCo, LLC v Porolis Technologies Pte Ltd [2026] SGIPOS 14, issued on 28 October 2026, Principal Assistant Registrar Gabriel Ong dismissed all five grounds of opposition (likelihood of confusion, damaging connection with a well-known mark, dilution, passing off and bad faith) and ordered OpenAI to pay S$10,000 in costs. Porolis filed the application on 22 May 2023 for gemstone authentication and artificial intelligence software services.

OpenAI relied on its earlier marks, including CHATGPT, GPT-3 and GPT-4. The Registrar found that, at the filing date, OpenAI had not established that the letters “GPT” alone identified its business. The decision noted that “GPT” was used as technical terminology among AI researchers before ChatGPT launched, and found CHATGPT and GemGPT similar only to a marginal degree. The Registrar accepted that CHATGPT is well known to the public at large in Singapore, but found that this reputation did not extend to “GPT” standing alone. On bad faith, the Registrar held that knowing of OpenAI did not, by itself, establish bad faith.

“We are grateful for a process that was rigorous, transparent and decided on the evidence,” said Vincent Wong, CEO of Porolis. “Singapore’s IP system gave a young start-up the same fair hearing as the world’s best-known AI company. That is exactly why we build here.”

“GemGPT does one thing – help the gem trade assess coloured gemstones like sapphire, ruby or emeralds using AI,” he added. “‘Gem’ is for gemstones and ‘GPT’ describes the technology. Now we can get back to work.”
