OpenAI has been refused registration of the trade mark "GPT" in the USA

The United States Patent and Trademark Office (USPTO) has rejected OpenAI's application to register the trade mark "GPT". This abbreviation stands for "generative pre-trained transformer" - the company's language model architecture.

Here's What We Know

USPTO specialists concluded that the term "GPT" is simply descriptive and denotes a whole family of neural network architectures used in AI. Its widespread use has led people to understand GPT as a general description of generative AI technologies, officials said.

Thus, the term cannot become a unique commercial designation for a specific product or service. Accordingly, GPT does not meet the criteria for granting legal protection as a trademark, the USPTO summarised.

OpenAI disagreed with this position, insisting that people would not understand the meaning of the phrase "generative pre-trained transformer." However, the company's arguments did not convince the patent office.
