developer(s),</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=789511308-13062008>We are currently in
the process of evaluating speech codecs for the transmission of wideband speech
(fs=16kHz) at bitrates lower than 32 kb/s. Speex is a contender for this task.
</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=789511308-13062008>Practically we would
have to port Speex to a specific 16 bit DSP if we would go for this. We should
be able to handle this.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=789511308-13062008>But we would like to
ask for your opinion regarding patent issues. If we go on the market with a
Speex solution we would ideally reach reach sales of 1 million pcs/year. This
could trigger a patent lawsuit where a third party holding a relevant or
non-relevant patent would try to get a share of our profit. We would of course
not like this situation therefore we would like to ask you how you see the risks
for the emergence of such a situation. More specifically:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=789511308-13062008></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=789511308-13062008>- Do you know of any
patents that might be used against a Speex-based product? I assume that Speex is
not violating any patents but regarding to US patent lawsuits everything is
possible, the judges/jurys have litttle technical insight.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=789511308-13062008></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=789511308-13062008>- Are there any
products on the market, selling in large quantities, that incorporate
Speex?</SPAN></FONT></DIV>

thank you in advance,</SPAN></FONT></DIV>
