How much time you have depends on where the opposition is happening. Response windows vary by jurisdiction. Once notified of an opposition:
- EU: a two-month cooling-off period begins automatically, during which both parties can negotiate a settlement. The cooling-off period is extendable to 24 months by mutual agreement. If no settlement is reached, both parties then have a set period to submit arguments and evidence.
- US: the applicant typically has 40 days to file an answer to the notice of opposition, with extensions available through the TTAB.
- UK: the opposed applicant has two months to file a counterstatement.
- Australia: the applicant has one month to file a notice of intention to defend.
Missing the initial response deadline in any jurisdiction results in the opposition being decided in the opposing party's favor by default.
