AFAIK these trademarks have only been non exclusive.
For Trademarks there is a distinction between exclusive
and non exclusive use - to name a easy to understand
US based example, there is the trademark 'White House'
(or Whitehouse or whitehouse) - this trademark is at
least owned by 10 different companies (including the
famous, but non of them exclusive.

Trademarks are normaly only given for a special product
class - for example, a PTC can trademark Touchtone
for their telephones, but a musical instrument company
can also trademark the same name for lets day a drum
computer. Sometimes a trademark could also be non
exclusive within a group. Gerneral Trademarks are
rare (or should be, but most trademark agancies today
grant them to easy - especialy if a BIG company wants
to take it).
