After successfully registering a trademark in Ireland, you need to perform the following maintenance work:

1. Trademark use: In order to maintain the validity of the trademark registration, you need to continue to use the registered trademark in Ireland . The trademark applies to goods or services consistent with the class specified in the registration application. Failure to use a trademark or not using it for a long period of time may result in the trademark becoming invalid.

2. Trademark monitoring: Regularly monitor the market for infringement or other trademarks similar to your registered trademark. If infringement is discovered, timely measures should be taken to protect your trademark rights, such as sending warning letters or taking legal action.

3. Trademark renewal: Irish trademark registration is valid for 10 years. Before the validity period of a registered trademark expires, you need to apply for trademark renewal on time to maintain the validity of the trademark. Renewal applications should be made within six months before the trademark expires.

4. Trademark change: If there is a change in the trademark holder, trademark address or trademark agent, the relevant change application should be submitted to the Irish Trademark Office in a timely manner.

5. Trademark licensing and transfer: If you want to authorize the use of a registered trademark to others or transfer the trademark rights to others, you should go through the trademark licensing or transfer procedures in accordance with the provisions of Irish trademark law.

6. Trademark registration: If possible, file your trademark registration in Ireland, which will help improve trademark protection and provide a stronger legal basis.

Please note that the above are generally maintenance matters after successful Irish trademark registration. Specific requirements may vary depending on the regulations of the Irish Trademark Office. It is recommended that you pay close attention to changes in relevant laws and regulations after registering a trademark, and regularly consult a professional trademark agency or lawyer to ensure that your trademark rights and interests are fully protected and maintained.
