The film studios - who already announced author JK Rowling will be writing the script for Fantastic Beasts and Where to Find Them, based in the wizard world she created - has also trademarked Quidditch Through the Ages.
The book of the same title, which is based on the fictional sport she created for the original novels, was one of two spin-offs released for charity Comic Relief in 2001, and both films could be kick-starting a new Harry Potter franchise.
According to BleedingCool.com, the company applied for several terms to be trademarked, including three hinting at the rumoured Quidditch movie.
Along with the title, Warner Bros also tied up team names Wimbourne Wasps, Chudley Cannons and Kenmare Kestrels, along with the original book's fictional author Kennilworthy Whisp.
Previously speaking about the Fantastic Beasts and Where to Find Them movie - which will follow its writer Newt Scamander - J.K. Rowling noted while it was set in the Harry Potter universe, it would not have a connection to the original story.
She said: "Although it will be set in the worldwide community of witches and wizards where I was so happy for seventeen years, Fantastic Beasts and Where to Find Them is neither a prequel nor a sequel to the Harry Potter series, but an extension of the wizarding world.
"The laws and customs of the hidden magical society will be familiar to anyone who has read the Harry Potter books or seen the films, but Newt's story will start in New York, seventy years before Harry's gets underway."
