Through various restyling processes over the year the present LOLLIPOP logo did not resemble the registered version at all. The differences were of such magnitude that the new logo did not fall under the scope of protection of the trademark registration. (A major difference was, for example the use of a big L in the registration) The consequence of this was that Lollipop could not prevent LOLLY POP from being registered.
Therefore: Always register your trademark as a wordmark if possible and ALWAYS check your registration when restyling.
