Prior art, which makes it easy to do away with.  I wouldn't worry about 
it.  Any big
company with an interest in JPEGs will bury them.

 Perhaps JPEG2000? (http://www.jpeg.org/JPEG2000.htm)  Supposed to 
 compress
better while preserving more data (well, probably one or the other, but
still..).
 Worst comes to worse, there's always MPEG I-frames.  Some camera 
 chips
already perform MPEG compression for short movies, so it probably wouldn't
be too difficult to modify them to just encode a single frame as an I-frame.
Mpeg requires a royalty already, but since it's already been paid for...

 Also, hasn't JPEG been out for something like 15+ years?  Isn't a 
 patent
only 17 years?  Doesn't that mean they've gotten a patent awarded for
something that is either prior art or about to expire in a few years anyway?

I think, it's more like creating codec software. 

And as far as png goes, I can already see it:

(Customer) Does this SuperDuper2000 camera outputs JPEG?

(SalesP) No, but it uses the fantastic Portable Network Graphic format
instead that allows...

Heck, I work in a software company, and I bet not more than half a
dozen people here have even heard this acronim.
Sigh...

 collecting licensing fees from those who create jpegs.  I wonder if 
 this will change any digital camera makers mind about offering a jpeg

 compression option or has it been out there too long.  Maybe it's 
 time we all switch to png.

Lol.  Sometimes I forget how insulated computer cultures can be.  My nine 
year old uses Linux, KDE, Gimp et. al, my wife who is pretty computer savy 
can't even stand to see the Linux login screen.
