[M4IF Discuss] Details of patent claims

[Iain Richardson (ensigr)]

Is there a statement available giving the details of the claims made by
the MP4 Visual patent holders ? For example, the short header mode is
identical to baseline H.263 which (as far as I'm aware) isn't covered by
a licensing scheme. Is there evidence that an MPEG4 Visual codec
operating in this mode actually requires licensing ?
Thanks
