Talk:Have the patents for H.264 MPEG-4 AVC expired yet?

Patents in other countries?

Is it possible to add patents in other countries (other than US and EU) for the High profile? The page for MPEG4 Visual already has this. 217.163.131.163 20:23, 10 May 2024 (UTC)

They are added.

If someone want to help, here are the two last MY patents with a priority before 2005-03-01, that according to VIA-LA are not yet expired:

• MY 140969
• MY 141699

However, according to this: For an application filed on or after 1 August 2001, the patent granted on it will be valid for up to 20 years from the date of filing [..] they should have been already expired in 2023-04-14, given they were both filed in 2003-04-14.

Patents from other countries

I wanted to ask, is not like patents from other countries also are valid within other countries, like Chinese patents are valid for USA, and USA patents are valid for EU?

maybe someone can answer with link to wiki Law SUBpage? 95.193.139.67 10:55, 3 March 2025 (UTC)

AFAIK, a patent is valid only in its own country. So, a Chinese patent doesn't apply to USA, and a USA patent doesn't apply to EU. PepitoSgazzebuti (talk) 15:05, 29 March 2025 (UTC)

all have a priority before 2005-03-01

Some of the remaining patents appear to have priority (and in some case filing date) after 2005-03-01... ~2025-38691-18 (talk) 16:49, 5 December 2025 (UTC)

Can you elaborate it a bit more here and edit the page adding these details? Thanks! PepitoSgazzebuti (talk) 19:45, 8 December 2025 (UTC)

Looking at the ones at the top of the list... it seems the some claims were addded somewhat later than than the original published draft

• [US7684489B2] 2010-03-12 Priority to US12/723,287
• [US9356620B2] 2016-05-06 Priority to US15/148,606

US7684489B2 was filed in 2004, how is it possible that it would have a priority date in the future? The same for the other one.

Taking 2026-02-01: US 7324593 (NTT DOCOMO, INC.) as an example, there are two updated version to the 2003 patent: in 2008 and 2010

2003-11-19 Application filed by NTT Docomo Inc

2003-11-19 Assigned to NTT DOCOMO, INC.

2004-06-10 Publication of US20040109500A1

2008-01-25 Priority to US12/020,362

2008-01-29 Application granted

2008-01-29 Publication of US7324593B2

2010-09-30 Priority to US12/894,850

In this case, I don't see any evidence that the 2003 version received a patent (although that may be just Google). The 2008 revision (and therefore only whatever was added in that revision) was accepted. I think the main issue here is the wording on the page around priority dates. It's fairly irrelevant, of course, as this is all decided by courts, not Google's website.

This site also has some info, where they show the Priority is earlier:

• https://portal.unifiedpatents.com/patents/patent/US-9356620-B2
• https://portal.unifiedpatents.com/patents/patent/US-7684489-B2

The applicable priority date is (for obvious reasons) the most recent before the patent is accepted, and the patent will include text:

This is a divisional of U.S. application Ser. No. 10/170,999 filed Jun. 14, 2002; the contents of which are hereby incorporated by reference in their entirety.

The key parts of that are "by reference" and the date. The granted patent does not apply to a failed application, and does not extend the period of claims for a successful application.

Time to determine a date

• confirm the date when Wikimedia Commons will allow mp4 file uploads - Community Wishlist/W524

I asked for the Wikimedia Foundation to determine and announce the date when we get mp4 files. Bluerasberry (talk) 16:35, 19 March 2026 (UTC)
