Should I register trademarks for sub-brands and SKU variations, or just protect the master brand?

Protect the master brand (word mark and/or logo) and skip registering individual SKU names and sub-brand variants. Members recommend registering only the core brand name with the UK IPO, which costs around £170 per application and can be done DIY via https://www.gov.uk/how-to-register-a-trade-mark — no need to pay lawyers £500+ per trademark.

**Why SKU variants don't need separate protection:** - SKU names and sub-product lines (e.g. "Duppy Share Spiced" or "Duppy Share XO") are extensions of the core brand, not unique IP in themselves - If you own the master brand (e.g. "Duppy Share"), enforcement against infringement is straightforward — you own the core - Registering the master brand gives you sufficient legal protection for product line extensions

**Key caveats:** - This approach is solid for UK operation. Global IP protection (EU, US, elsewhere) becomes "horribly complicated" and may require different strategy - Ensure you own both the word mark and logo for the master brand to be fully covered - Do-it-yourself registration via the IPO is described as "pretty quick and easy"
