I compared the two websites - they are copywise exactly the same (the design is a bit more "modern", but still nothing special in terms of today's website design...).
The only differences are one or two pieces of copy, which are at a different place - and TPL/Alliacense as additional contact in the "Contact us" corner.
Interesting, that they point to www.ptsc.com on the "company" site to get MORE information about Patriot - so far there is NOT more information on ptsc.com. One can ask, what the purpose of this website might be - could/will it be the "holding" website???
If the ptsc.com disappears it might speak for the start of a change in communications.
IMO - enjoy your sunday!
