What is the scope of patent grants made to the ASF?
This is a four part question:

Q1:If I own a patent and contribute to a Work, and, at the time my contribution is included in that Work, none of my patent's claims are subject to Apache's Grant of Patent License, is there a way any of those claims would later become subject to the Grant of Patent License solely due to subsequent contributions by other parties who are not licensees of that patent.
A1:No.
내가 특허 청구항이 아파치의 특허 라이센스 허가가 되지 않게 작업물을 만들었을 때, 나중에 그 특허를 소유하지 않은 다른 자가 후속 기여를 한 경우에만 홀로 아파치의 특허 라이센스 허가가 가능하게 할 수 있는 방법이 있나요?

이런 번역 맞나요?

Q2:If at any time after my contribution, I am able to license other patent claims that would have been subject to Apache's Grant of Patent License if they were licenseable by me at the time of my contribution, do those other claims become subject to the Grant of Patent License?
A2:Yes.
만일 내가 기여를 한 후 언제라도 (만일 내가 기여를 하게 될 경우 특허청구항이 라이센스할 수 있다면, 나는 아파치 특허 라이센스 허가의 지배하에 있던 다른 특허 청구항을 라이센스할 수 있다.) 다른 청구항이 특허 라이센스 허가의 지배하가 되는 건가요?

무슨 말인지 모르겠습니다.

Q3:If I own or control a licensable patent and contribute code to a specific Apache product, which of my patent claims are subject to Apache's Grant of Patent License?
A3:The only patent claims that are licensed to the ASF are those you own or have the right to license that read on your contribution or on the combination of your contribution with the specific Apache product to which you contributed as it existed at the time of your contribution. No additional patent claims become licensed as a result of subsequent combinations of your contribution with any other software. Note, however, that licensable patent claims include those that you acquire in the future, as long as they read on your original contribution as made at the original time. Once a patent claim is subject to Apache's Grant of Patent License, it is licensed under the terms of that Grant to the ASF and to recipients of any software distributed by the ASF for any Apache software product whatsoever.

깁니다.

Q4:What is an Apache product?
Q3:An Apache product is a body of software being developed by the ASF that the ASF intends to both alter and to publish as a separate line of releases.
alter와 따로 릴리스된 배포 두 경우 모두

alter가 뭔가요?
