FFW IP partner makes US switchField Fisher Waterhouse (FFW) IP partner John Olsen, who took his firm to an employment tribunal, has left to join the London office of US firm Edwards Angell Palmer & Dodge.

Olsen had been with FFW since joining from SJ Berwin in 1999 and was most recently head of ­trademarks at the firm. Last September, at the age of 60, he lodged a claim against FFW with the London Central Employment Tribunal alleging harassment and age discrimination.

In his internal grievance document, Olsen claimed he joined FFW with a book of business worth £2m, which subsequently ;grew ;to around £5m. The grievance stemmed from the fact that IP head and Europe chief Mark Abell questioned an expense claim for client Elizabeth Arden, despite Olsen’s status as a senior equity partner.

Jo Keddie, head of employment at Dawsons, represented FFW, while Mishcon de Reya dispute resolution chief James ­Libson acted for Olsen, but the claim settled before it hit the courts.

Neither ;FFW ;nor Edwards Angell could be reached for comment.
