The license link. Can someone elaborate "NONINFRINGEMENT OF THIRD PARTY RIGHTS"? What is being implied here? It's confusing to me. I will choose the answer with most votes.

As I read it, it means that if your use of IBM's software causes somebody else to sue you for infringing their rights (whether copyright, patent rights, trademark rights, or, I suppose, the right to pass unimpeded upon the highway) IBM have in no way warranted that this will not come to pass. Had IBM given you such a warranty, and had some third-party then successfully sued you, you would have reasonable grounds for a suit against IBM, to recover at least some of your costs.

The licence reads very much like the MIT licence; I rather suspect the ICU came out of passing MIT through IBM's legal department, who have tightened up some of the language a little. Both ICU and MIT licences disclaim all warranties; but in the non-exhaustive list of such warranties that follows, MIT disclaims all warranties of non-infringement, which is a broader disclaimer than ICU's (a mere warranty of non-infringement of third-party rights). So if MIT's warranty disclaimer is valid (and I have no reason to think it not so) then so is ICU's.

  • When can that happen? Say(logically) someone can only sue me(because of me using IBM code) if the IBM code already does that. Otherwise who can blame IBM, just because I had infringed another party's right. Isn't it redundant. Sake of clarity perhaps. Dec 4 '21 at 8:10
  • @SomOneElse read the second half of my first paragraph. It's you suing IBM that IBM's worrying about in that particular clause.
