MPEG-LA updated their site recently.
"This is the list of patents (Attachment 1) covered by the MPEG-2
Patent Portfolio License as of January 1, 2018. Under the MPEG-2
Patent Portfolio License, royalties are payable for products
manufactured or sold in countries with an active MPEG-2 Patent
Portfolio Patent at the time of manufacture or sale. Please note that
the last US patent expired February 13, 2018, and patents remain
active in Philippines and Malaysia after that date."
PS I've never heard that software patents are valid anywhere but USA
and South Korea, so mentioning Philippines and Malaysia was a surprise
With best regards, Peter Lemenkov.
