You can use ® for registration in other countries/regions too. In UK/EU it's not registered until the end of the opposition period.

GPT and Blender are both generic terms, unless the combination is already being used or is registered then it appears - and of course this is not legal advice - that there is no infringement.

Indeed I think registration of GPT before USPTO has been refused because it is generic.

You might be breaching contract, assuming you're using ChatGPT behind the scenes, no idea; in theory they could require you not to use GPT in your product name.

Of course, being in the right is not enough. Companies/organisations can still go after you.

> Blender has been registered as a trademark by Blender Foundation in USA and EU. It has been used by Blender Foundation since 2002, and it’s a well recognized brand now. Although the name ‘Blender’ is a generic word (for a mixer), in the context of products or company names related to software it’s protected by trademark law.

Trademarks are categorical so just because Blender is an English word does not make it generic.

Two entirely different companies can even have the same trademark in two different areas of business.

GPT is generic. Blender is not, unless you're talking about kitchen equipment.
