Submission + - CSP 2.0 Patent Troll Datawing Backs Off (theregister.com) 1
The director of a tiny UK company has apologised after sending letters to businesses suggesting they had infringed his patents that he claimed covered an age-old web standard.
Datawing Ltd sent a number of letters to small businesses this month claiming to own one UK and one US patent on CSP and its use of a nonce. After an initial wave of alarm and outrage on Twitter when the letters surfaced, The Register tracked down their author: a penitent William Coppock.
The letter claimed "our patent has been widely overlooked by companies since the inception of CSP 2.0 in 2014," advertised Datawing's Scriptlock product which "augments CSP 2.0 with new features which greatly reduce the cost of adding CSP support to existing websites," and suggested that if companies weren't interested in Scriptlock, they should "obtain a licence to work the patent."
"Technical information is enclosed with instructions for how to register with us and license fees," it concluded.
