Accounting Office Software has backed down from accusations it made this summer that software giant Iris had infringed on Accounting Office’s registered trademarks.

The issue arose with the launch of Iris Accounts Office software, a name which Accounting Office claimed infringed on its trademarks.

Accounting Office has been forced into a u-turn, however. ‘We accept we were entirely mistaken about the legal basis for our complaint and that the Iris Accounts Office accounting product does not infringe any of our intellectual property rights,’ said MD Ian Richards.

Iris always maintained that Iris Office Accounts had been correctly trademarked. ‘Their admission proves a wholly unjustified allegation and we were appalled that the company chose to contact the press without giving us an opportunity to respond before it was made public,’ said Neal Roberts, Iris FD.
