Dutch firm NautaDutilh is mourning the loss of John Allen, a well-regarded intellectual property attorney who was among the 298 victims killed aboard Malaysia Airlines Flight 17, which was struck down by a missile over war-torn Ukraine last week.

Allen, 44, died with his wife and three sons, who were also on the flight. In his memory, NautaDutilh changed the homepage of its website to include an image of its beloved attorney, who had worked at the firm for 18 years.
