RNA, PCR, and GPT all have precisely the same problem: the acronyms are purely technical.
- ribonucleic acid
- polymerase chain reaction
- generative pretrained transformer
You can't trademark the phrase "polymerase chain reaction" because there are many types of polymerase chain reactions, not just the ones used for copying DNA. [ETA: specifically I mean "copying DNA at commercial scale" i.e. the patented biochemical engineering techniques.] Likewise a generative neural network using pre-training with a transformer architecture is simply too generic to trademark "generative pretrained transformer." And if you can't trademark the phrase you can't trademark the acronym.
Is this actually true though? KFC is able to trademark their name and acronym (I believe their trademark is for the acronym officially), even though they’re selling Kentucky-style fried chicken?
IBM doesn't sell products called "international business machines" and hold a trademark on that product name, which would force competing manufacturers to call them "devices for transcontinental enterprise" etc. IBM is a business name, that's a different thing. More importantly, nobody calls computers "international business machines," that name reflects IBM's 19th-century origins, so having a trademark on "International Business Machines" has no impact on competing businesses.
A hypothetical 1930s computing company called Central Processor Units would have probably changed its name in the 1950s, since "CPU" wouldn't be trademarkable and their brand name wouldn't be worth very much. (A trademark on "CPU" would be needlessly detrimental to other computer manufacturers, or at best confusing, especially after the von Neumann architecture became the universal standard.) Of course in this alternate universe maybe CPUs would have been called something else, and maybe if IBM never existed we would be calling computers "business machines."
IANAL but I think it's a mistake to apply "If A then B" rules to this stuff and try to invalidate reasonable guidelines based on specific counterexamples. Judges need to consider how language is actually used in context by the people working in those areas. This is why the USPTO cited so many businesses and practitioners using GPT in a generic context.
