Anyway the [[Carter]] pens were of excellent quality (with nothing to envy to the most famous ones done by [[Waterman]], [[Sheaffer]] and [[Parker]]). The [[De Witt-La France]] owned also some significant patents, one for a very functional and easy to produce spring clip ({{FPO Patent|1350412}}), another one for a tethered [[lever filler]] system ({{FPO Patent|1209978}}), that allowed to limit vertically the travel of the lever, and another one for an efficient feeder ({{FPO Patent|1340277}}), all these features can be found on [[Carter]] pens.
