Unknown Property error with Custom Controller

I have a custom controller and a Visualforce page and every time I try to save the page, I get the error:
Error: Unknown property 'TMCR_AssocInventorController.inventors'
I can't seem to figure it out. My problem seems to be identical to another entry: https://developer.salesforce.com/forums/ForumsMain?id=906F000000096uoIAA however it's been of no use as I still get the error.

Any help is much appreciated!

Here's the Visualforce page: 
<apex:page Controller="AssocInventorController" tabstyle="Case">
    <apex:pageBlock title="Associated Inventors" >
    <apex:pageBlockTable value="{!inventors}" var="ai">
        <apex:column headerValue="Id"><a href="/{!ai.Id}">{!ai.Id}</a></apex:column>
        <apex:column headerValue="Inventor"><a href="/{!ai.Inventor__c}">{!ai.Inventor__c}</a></apex:column>
        <apex:column headerValue="Inventor Type">{!ai.Inventor_Type__c}</apex:column>
        <apex:column headerValue="Role">{!ai.Role__c}</apex:column>
    </apex:pageBlockTable>
    </apex:pageBlock>
</apex:page>
And here's the Controller: 
public with sharing class AssocInventorController {
	public List<Associated_Inventor__c> Inventors {get{
		if (Inventors = null){
			Inventors = getInventors();
		}
	}private set;}
	public List<Associated_Inventor__c> getInventors() {
		return [
			select id, Inventor__c, Inventor_Type__c, Role__c 
			from Associated_Inventor__c 
			where SF_ID__c = :System.currentPageReference().getParameters().get('id')
			group by Inventor__c
			order by Case_Filing__r.Name asc
		];
	}
}

Please try below code :-

Page :- 
<apex:page Controller="AssocInventorController" tabstyle="Case">
    <apex:pageBlock title="Associated Inventors" >
    <apex:pageBlockTable value="{!inventors}" var="ai">
        <apex:column headerValue="Id"><a href="/{!ai.Id}">{!ai.Id}</a></apex:column>
        <apex:column headerValue="Inventor"><a href="/{!ai.Inventor__c}">{!ai.Inventor__c}</a></apex:column>
        <apex:column headerValue="Inventor Type">{!ai.Inventor_Type__c}</apex:column>
        <apex:column headerValue="Role">{!ai.Role__c}</apex:column>
    </apex:pageBlockTable>
    </apex:pageBlock>
</apex:page>

Class :- 
public with sharing class AssocInventorController 
{
	public List<Associated_Inventor__c> Inventors {
	get{
		if (Inventors == null){
			Inventors = getInventors();
		}
		return Inventors;
	}
	private set;
	}
	
	public List<Associated_Inventor__c> getInventors() 
	{
		return [
			select id, Inventor__c, Inventor_Type__c, Role__c

below code should work  
public with sharing class AssocInventorController {
	public List<Associated_Inventor__c> Inventors {
	  get{
	     
		 
		 if (Inventors==null)
		 {
			Inventors = getInventors();
		 }
		 return Inventors;
	    }private set;}
	public List<Associated_Inventor__c> getInventors() {
		return [
			select id, Inventor__c, Inventor_Type__c, Role__c 
			from Associated_Inventor__c 
			where SF_ID__c = :System.currentPageReference().getParameters().get('id')
			group by Inventor__c
			order by Case_Filing__r.Name asc
		];
	}
}
