PATMA: Patent attorneys

Within: PATMA: Patent attorneys

According to one client, 'the quality of advice at Dehns is outstanding' and the team is 'very effective at patent prosecution and invalidation attack and defence'. Leading the team is Alexander Piésold, Hanna Dzieglewska (head of biotechnology), Philip Towler (head of the chemical group), and John Tothill (head of engineering). Other key figures include Mark Bell, who worked with the US lighting products company Cree on its European patent applications and Laura Ramsay, who assisted Isansys Lifecar with the granting of a patent for its wireless cardiac monitoring device 'Lifetouch Sensor'. Patent portfolio management is a key specialty of Chris Goddard, who recently worked with Camurus on its portfolio. Matthew Hall and Adam Taylor conducted due diligence for EQT on the IP portfolio of its target company AutoStore. Associate Daniel Rowe drafted and filed the patent application for a test kit which measures bacteria and is used to detect bowel conditions. Alex Robinson, Barbara Rigby, Christopher Wilkins and Phillip Price are also recommended.
