"The creator of iTrump first clashed with the Trump Organization in January 2011, when the billionaire's lawyers alleged the trumpet simulator's name falsely suggested a link to the tycoon.
After defeating this claim, the developer then went on the attack.
And this resulted in the company losing a key trademark of its own last week.
On 11 August, the US Trademark Trial and Appeal Board cancelled the New York-headquartered company's exclusive right to use "Trump" in relation to entertainment services, including reality TV shows.
The ruling followed earlier victories by San Francisco-based Tom Scharfeld, in which he prevented the Trump Organization from owning the exclusive right to use "Trump" in connection with computer games, golf-related mobile apps and music streaming."
