ELI5: Explain Like I'm 5

Interference proceeding

An interference proceeding is like when two kids want to play with the same toy at the same time. They both believe that it is theirs and they should feel that they have the right to use it. Sometimes, the kids' parents need to step in and figure out who had the toy first or who has the better right to use it. That way, both kids can stay happy and there won't be any fighting. Similarly, an interference proceeding is a legal process to help solve a dispute between two people or companies who both claim they have the right to use something like a patent or a trademark. A judge will listen to both sides and make a decision about who should have the right to use it. This helps to prevent arguments and makes sure everyone follows the rules.
