The use of Liardet’s stucco by Robert and James Adam has often been noted. The dispute with John Johnson, about alleged infringement of the patent, is well known because of the pamphlet warfare which occurred in 1778 and because it was for many years regarded as a leading case in patent law. But Liardet v. Johnson was only the first of three major lawsuits which embroiled the brothers between 1777 and 1787. Although they were successful it was a pyrrhic victory. By 1780 the deficiencies in the stucco were becoming apparent. The brothers faced a major claim for damages from Lord Stanhope and their agreement with Liardet collapsed in recrimination.

5 PRO/C. 12/1346/22. The case has been discussed recently by John Adams at the Legal History Conference at the University of East Anglia injuly 1983; I am grateful to Mr Adams for allowing me to read and make use of his text. His conclusion is that Liardet v. Johnson is not the landmark in the history of patent law that many legal historians have taken it to be.
