A Note about Patents:

The patents referenced below fall into two distinct categories:  Utility patents and Design patents.  As their names would suggest, a Utility patent is for a novel technology which, in this case, has been incorporated into the design of a vacuum coffee pot; whereas a Design patent is for the aesthetic or ornamental aspects of the vacuum pot.  Design patents are designated by the letter "D" preceding the patent number.  Utility patents tend to be the more interesting, since they include a description of the operation of the device, with the inventor's claims and specifications.
