The major practical differences between the UK, US, EU, and Australia are as follows.

Filing basis: the US is the only major jurisdiction requiring a use-in-commerce or intent-to-use declaration. The UK, EU, and Australia do not require evidence of use at the application stage.

Examination of relative grounds: the USPTO and IP Australia examine for conflicts with earlier marks as part of their examination process. The EUIPO and UKIPO do not raise relative grounds on their own initiative; these must be raised by third parties during the opposition period.

Opposition window: 30 days in the US (extendable); two months in the UK; three months in the EU; two months in Australia.

Post-registration use requirements: the US requires a Declaration of Use between the 5th and 6th year after registration. The UK, EU, and Australia do not have this mid-term requirement, though all permit non-use cancellations after five years of non-use.

Timeline: EU and UK registrations are among the fastest (4–5 months unchallenged); US and Australian registrations take longer (12–14 months and 6–7 months respectively).
