Hi Dimitri,
While I cannot discuss specifics of the case, defending patented
intellectual property is the right and responsibility of any company that
has invested as much as Lizardtech has into their underlying technology and
products. As a software developer, I find it surprising that protecting
your own IP that is integral to your products would be distasteful. This is
not like Amazon, claiming patents to every business process, these are real
mathematical algorithyms and methods that Lizardtech paid to license from
LANL.
Additionally, we have continued to move the technology forward in ways that
no competitors have yet done and intend to continue to do so.
I really don't know what you mean by eggregious and perhaps we can take that
discussion offline. The decode SDK is used by almost every GIS vendor on
the planet so I don't see how it could possible be that restrictive. Anyone
can freely distribute our browser plugins and the decode SDK requires a
signed license agreement, since we have reporting responsibilities to LANLit
does not involve royalties and there is a nominal fee to get into our
program (to cover administrative overhead) unless you opt for developer
support.. The encode SDK, of course, is not free and I can assure you that
you will also get a price tag from ERM to use their unlimited encode SDK as
well.
I hope this helps clear things up and if not, I welcome further dicussion
in an offline thread. That said, ew would be delighted for Manifold to
support the latest version of MrSID.
best regards,
-Karen

Karen,
Is LizardTech still pursuing that unfortunate lawsuit against Earth
Resources? Like many software developers, that left a bad taste in our
mouth and is one of the reasons the most rapidly growing GIS package does
not support MrSID. I'm curious to hear if things have changed on the legal
front, and also whether LizardTech intends to reform the more egregiously
anticompetitive terms of the "free" MrSID license, to say, bring it more
into line with what is done by companies like Microsoft with its licensing
or Earth Resources with ERMapper/ECW. These would be positive steps in
building momentum to allow more companies to support MrSID in addition to
"open" alternatives. What's your take on all this?
Cheers,
Dimitri
