Editing Richard Arkwright (section)

===Grand Patent===
To strengthen his position in relation to his many competitors and emulators, Arkwright obtained a "grand patent" in 1775, which he hoped would consolidate his position within the fast-growing cotton industry. Public opinion, however, was bitterly hostile to exclusive patents, and in 1781 Arkwright initiated legal proceedings to assert his rights. The case dragged on in court until 1785, when it was finally settled against him on the grounds that his specifications were deficient: the court had also heard assertions that the spinning frame was actually the invention of Arkwright's employee [[John Kay (spinning frame)|John Kay]], or of [[Thomas Highs]], Kay's previous employer.{{Citation needed|date=August 2014}}
