Quoting Greg Roelofs (member, PNG Group; author, PNG: The Definitive
Guide; maintainer, PNG and MNG home sites; hacker, lots of PNG-related
tools)

"The PNG group (which includes at least one or two members of the W3C's
SVG team, btw) did discuss the Apple patent several weeks ago, and we
decided it was completely irrelevant to PNG itself, almost certainly
irrelevant to the pnmtopng utility and to PNG's animated extension, MNG,
and probably irrelevant to SVG, as well. And that's where the
discussion--and the "perturbation"--ended, for the most part. In short,
PNG alpha is identical to the version described in Porter and Duff's
1984 SIGGRAPH paper, which precedes Apple's filing by 8 years."
