No. Sony developed ATRAC in-house, not violating any Dolby Laboratories
patents. Then sometime after ATRAC v4.5 they collaborated with Dolby
Laboratories to make improvements for mutual benefit. The results are that
Dolby Digital has some of ATRAC in it and current versions of Sony ATRAC
have some AC3 in them.
One side effect of that deal is that Sony no longer discloses ATRAC versions.
