Can I get my registered trademark renewed after it has expired?

Trademark law does provide a grace period after the original expiry during which you can still apply for restoration of the mark, generally by paying the renewal fee along with an additional surcharge for the delay — this route, where still available given how much time has passed, is usually simpler than starting an entirely fresh application.

If the grace period for restoration has also lapsed, you would need to file a fresh trademark application, which carries a meaningful risk — if someone else has registered an identical or similar mark for similar goods/services in the interim, this could complicate or even block your fresh application.

Given the time-sensitivity involved, it's worth checking the exact status and applicable deadline for your specific mark with a trademark professional as soon as possible, rather than delaying further, since your options and the associated cost/risk generally get worse the longer you wait.
