    This is one of the better written patents I have seen.

      The mechanism is massively overcomplicated. It almost looks like a joke.

        It looks like the design goal was "How can I turn a traditional mousetrap into a humane mousetrap?" There would be more efficient ways to build the same product from scratch, but it's a fun thought experiment.

          There’s far simpler, already existing humane mouse traps. Where you have a small cage with an opening at one side, the opening as door pulled up against a spring which would push it down, and then locked with a lever. If the mouse touches the cheese, the spring-release of that activates the lever of the door, and traps the mouse in. https://www.knauber-freizeit.de/mam/celum/celum_assets/8804179476510_05340_5801_jpg.jpg https://www.knauber-freizeit.de/mam/celum/celum_assets/88041...

  I've seen this being sold at a local big-name hardware store.
