For everyone that is looking for a general idea on how to check a license for a grasshopper component, @menno provided an answer in a private conversation but he pointed out that this should be posted public so other people in the future can benefit from it. I totally agree with that :slightly_smiling_face:

Below you can find the code that @menno provided on how implement the license check in grasshopper:

public class MyCategoryIcon : Grasshopper.Kernel.GH_AssemblyPriority
{
  public override Grasshopper.Kernel.GH_LoadingInstruction PriorityLoad()
  {
    bool ok = CheckLicense(); // this you need to implement yourself
    if (ok) 
    {
    Grasshopper.Instances.ComponentServer.AddCategoryIcon("MyCategory", somebitmap);
    Grasshopper.Instances.ComponentServer.AddCategoryShortName("MyCategory", "MyCat");
    Grasshopper.Instances.ComponentServer.AddCategorySymbolName("MyCategory", 'M');

    return Grasshopper.Kernel.GH_LoadingInstruction.Proceed;
    } 
    else 
    { 
       return Grasshopper.Kernel.GH_LoadingInstruction.Abort; 
    }
  }
}

The code above was the last piece of information I was needing to complete the license check for the grasshopper component I am developing. Keep in mind that you need to come up with your own license checking mechanism.
