It has both. Go check for yourself. Most of those names on that list DO NOT have a generic Seroquel XR approval yet
If you take a second look at the numbers Fred gove us, you will notice Accord has biggest sales. Accord was the first to get generic XR approved a year ago, but it was only 400mg tablet. Accord does not yet have 50mg strength at all.
Lupin has second big sales. It got approval together with IPCI, PAR, Pharmadax and Accord for other strengths. This happened may 17 this year as we all know.
AstraZeneca is of course the original manufacturer and it has had XR version since 2007.
So - IPCI/MNK should be quite much at the same level at least with PAR and Pharmadax. Accord entered market second, but it does not have 50mg strength.
Accord sales is more than 150 times bigger than MNK and Lupin sales is more than 50 times bigger. Even thoug they did have approval the very same day as IPCI.
