Ok guys I do have the pattern saved to a .pat file. These patterns are images of carpet and they are labled by style-color. They are all in the same library because they are all for the same project. I can get the name and Id for each one of these, but how do I get photoshop to put the pattern name as the layer name. With out having to type up a script for each pattern. I will only be using each pattern once.
Let me explain alittle better.
Here is the proccess I am going through now. I am makeing a monster file with a Fill Pattern layer for every carpet. I have linked the pattern to the layer so when I change the canvas size the patterns will auto generate to the canvas size.
Right now these are the steps for each layer.
1.) Create new Fill Pattern layer
2.) Select the pattern that I want to use.
3.) Name the Layer (Useing info from spreadsheet)
( I have to do this 2000 times) - I am on # 150 right now!?!? 
This is what I would like to do.
1.) Create all of my fill Layers and leave the standard name Pattern Fill 1, 2, 3 etc....
2.) Run a script that will replace the stadard name (Pattern Fill 1) with the name of the pattern that the layer is filled with.
I agree with Christoph it would be easier to create all the layers IE:-
#target photoshop
main();
function main(){
var file = File.openDialog("Please select Pat file");
if(file == null) return;
if(!documents.length){
var doc = app.documents.add(UnitValue(300, "px"), UnitValue(300, "px"),72,"Patterns");
}
file.open("r");
file.encoding = 'BINARY';
var str = file.read();
file.close();
var patterns=[];
//Thanks to X for the regex
var re = /(\x00\w|\x00\d)(\x00\-|\x00\w|\x00\s|\x00\d)+\x00\x00\$[-a-z\d]+/g;
var parts = str.match(re);
for (var i = 0; i < parts.length; i++) {
var p = parts;
var sp = p.replace(/\x00/g, '').split('$');
patterns.push([[sp[0]], [sp[1]]]);
}
//load pattern file
app.load(file);
for(var a in patterns){
fillPattern(patterns[0].toString(),patterns[1].toString(),100);
}
};
function fillPattern(name, id, opacity) {
activeDocument.artLayers.add();
activeDocument.activeLayer.name = name;
var desc6 = new ActionDescriptor();
desc6.putEnumerated( charIDToTypeID('Usng'), charIDToTypeID('FlCn'), charIDToTypeID('Ptrn') );
var desc7 = new ActionDescriptor();
desc7.putString( charIDToTypeID('Nm '), name );
desc7.putString( charIDToTypeID('Idnt'), id);
desc6.putObject( charIDToTypeID('Ptrn'), charIDToTypeID('Ptrn'), desc7 );
desc6.putUnitDouble( charIDToTypeID('Opct'), charIDToTypeID('#Prc'), opacity );
desc6.putEnumerated( charIDToTypeID('Md '), charIDToTypeID('BlnM'), charIDToTypeID('Nrml') );
try{
executeAction( charIDToTypeID('Fl '), desc6, DialogModes.NO );
activeDocument.activeLayer.visible=false;
}catch(e){app.activeDocument.activeLayer.remove();}
};
