英语邮件抱歉之前邮件没有写明这些缩写含义我应该说清楚的。to be updated是指regional IP仍在努力收集信息预计随后会提供进一步信息。not appliable是指这个item在改区域不使用。no visibility是指regional IP已尝试但收集不到信息IP不清楚这个item是如何source来的且咨询了stakeholder如RDDC的同事但没有得到确切的答案

Dear [Recipient],

I apologize for not clarifying the meanings of these abbreviations in my previous email. It is important for me to provide clear explanations.

"To be updated" means that the regional Intellectual Property (IP) team is still actively gathering information and is expected to provide further details soon.

"Not applicable" indicates that the mentioned item is not used in the specific region.

"No visibility" means that the regional IP team has made attempts to collect information but has been unsuccessful. The IP team is unsure about the source of this item and has consulted stakeholders, such as colleagues from RDDC, but has not received a definitive answer.

Once again, I apologize for any confusion caused by the lack of explanation in my previous email. If you have any further questions or require additional clarification, please let me know.

Thank you for your understanding.

Sincerely, [Your Name
