Last month, @RODENT950 alleged that Huawei was planning to release the Watch GT 3 this quarter, possibly alongside the Watch D and Watch FIT 2. However, Sony has sued Huawei and the European Union Intellectual Property Office (EUIPO) to prevent the former from selling any further Watch GT products. The dispute actually dates to 2016 when Sony objected to Huawei registering GT3 and GT5 with the EUIPO.
In short, Sony believes that 'GT' belongs to it as a shortening of Gran Turismo. While the Gran Turismo series and Watch GT series operate in different markets, Sony could be keeping its options open about releasing a GT-themed smartwatch in the future. So far, Sony has brought cases against Huawei and EUIPO regarding the terms GT3, GT5, GT8, GT9 and GT10.
Neither Huawei nor Sony have commented on the dispute. Huawei has responded by registering GT3, GT5, GT8, GT9 and GT10 with the UK IPO. Incidentally, Huawei's trademark applications specifically exclude use with 'computer games software, computer games hardware, video games software, video games hardware', a possible reference to Gran Turismo and Sony. The UK IPO is still considering Huawei's applications, which it filed on September 27, 2021.
