Mpeg-2 patents have now expired in most countries at the beginning of 2018. However, at least Malaysia and Philippines still have active mpeg-2 patents.

So does anyone know when mpeg-2 patents expire in Malaysia and Philippines ?

Addition: I've written an mpeg-2 decoder and wondering when I can give it away free.

  • That's a pretty big question. There is no "the mpeg-2" patent which we could just look up. There might be a more or less complete list of relevant patents somewhere because it's such a big standard, but per se, the question would require researching in every country any possibly relevant patent. – DonQuiKong Nov 27 '18 at 10:25

  • @Glorfindel use the rollback function in edit mode, review doesn't show the edit history so it's hard to check your edit else. But you're right of course, I rolled it back and flagged for moderator attention in case this goes on. – DonQuiKong Jul 10 at 17:06
  • AFAIK there is no rollback for suggested edits; all you can do is select another revision as starting point (which I did). – Glorfindel Jul 10 at 17:29

The wikipedia page for MPEG-2 contains a statement about Malaysia and the Philippines.

As of April 1 2019, only Malaysia and the Philippines still have active patents covering MPEG-2. Patents in the rest of the world have expired, with the last US patent expiring February 23, 2018.[30]

I assume that is the basis for the question. The footnote [30] for the sentence references a document -

"MPEG-2 Attachment 1" (PDF). MPEG LA. Archived (PDF) from the original on 29 May 2019. Retrieved 29 May 2019.

I have a link to that reference below. It seems to be a list of MPEG-2 patents by patent owner. The first page lists patent numbers in the two countries you asked about. Assuming this is authoritative, you could look up those patents and get an answer.
