1, United States In the United States, trademark applications can be based on "expected use" and "used". If a trademark is applied for on the basis of "intentional use", the Trademark Office will issue a "Notice of Approval of Registration" to the applicant about 2 months after the announcement of the trademark. The applicant shall submit the affidavit of use and relevant evidence within 6 months after receiving the notice, and pay the relevant oath fee. In addition, it is necessary to submit the oath of use and relevant evidence of use between the fifth and sixth years after registration. And every time you submit an application for renewal, you also need to submit an affidavit of use and relevant proof of use. 2. Philippines In the Philippines, the actual use oath (DAU) must be submitted in the third year after the trademark application is submitted, otherwise the trademark will be automatically revoked. The Philippines "Practical Use Oath Guide" stipulates that the trademark owner must sign and notarize the DAU in the prescribed form within the prescribed time limit (you can apply for an extension of 6 months), and submit it together with the evidence of the actual use of the trademark (such as product labels, instructions, etc.) (the official will not inform the trademark owner to submit the DAU at that time). In addition, in the fifth year (within the fifth anniversary) after the trademark registration, it is also necessary to submit the oath of trademark use and related evidence. 3. In the 5th-6th year after the trademark registration in Cambodia, the use/non-use oath shall be submitted in the 5th-6th year after the trademark registration is completed. If it is not submitted, it may be revoked. However, if the customer submits an oath of use/non-use within 5-6 years after registration, the trademark will not be revoked whether it is used or not.
