Lowell v. Lewis
Circuit Court, District of Massachusetts
15 F. Cas. 1018 (1817)
Lowell (plaintiff) sued Lewis (defendant) for infringement of a patent to a water pump. Lewis also held a patent to a water pump, but this second patent was issued after the Lowell patent. At trial Lewis argued that his patent was distinct from the Lowell patent, and in fact constituted a significant improvement. Further, Lewis argued that the Lowell patent was not valid for failing to be new or useful.
