a patent pending kettle typically means it's stamped as such on the vent, whereas yours is stamped "M". while i'm sure they had a patent pending on the thermo housing mount thingy, that's not typically what people mean.
Nice job cellar...great looking handles!
The blue EO (1995) SSP I just took possession of today has PAT PENDING stamped on the thermometer housing.
