Ignoring a cease-and-desist letter can cost you everything. Courts view silence as admission, and you'll face injunctions plus their legal costs on top of yours.
Don't Ignore It
Even if you think it's baseless, respond professionally. Silence = admission in some cases.
Get Legal Advice Immediately
Contact trademark attorney (£200-£400 for initial consultation). Don't negotiate alone.
Assess Validity
Do they have a registered trademark? Same industry? How similar are the names?
Your Options
Rebrand (cheapest), negotiate coexistence agreement, challenge their trademark, or fight in court (£50,000+).
Timeline Pressure
Most letters demand response within 7-14 days. Act fast.
