<p class=MsoNormal style='margin-bottom:12.0pt'>A quick glance at some of the
Agilent patents show that US 5566180 would definitely infringe (not that I am a
lawyer). It is essentially the 1588 protocol. Most the "Letters of
Assurance" received by IEEE from Agilent on this subject do not exclude
charging license fees, merely guarantee license will be provided to all
interested parties. <br>
<br>
It seems to me that it is not the code as such that is the problem, but message
algorithm. Hence there should be simple answers to our questions:
National Instruments, Intel, IXXAT, Hirshman etc are all selling products that
use the protocol (whether in soft or hardware) and either all pay nominal license
fees or Agilent isn't interested in charging it.<br>
<br>
I will get our lawyers involved in 2 weeks if I don't find out anything in the
meantime.<br>
<br>
Cheers and thanks<br>

I would like to add my voice to request for patent info. We have (had ?)
every intention of running Ptp on some of our products and are far down the
development road. I am in the middle of sorting out other GPL license
issues when finally looked at the patent note and now see your e-mails.<br>
<br>
We would be very interested in knowing whether the original code on sourceforge
(by Kendall) breaches any patents. I do have access to a team of lawyers
( I work for very large corporation) , but I want to find out a little
more if I can, or at least be able to direct them better.<br>
<br>
Much appreciated<br>
<br>
