This is the most level headed approach to IP I’ve seen. If you’re not willing to use the property you forfeit it. It’s a common contact for licensing rights for movies that forces a studio to make a movie or lose rights. That way people can’t squat on a licence to prevent others using it.
I don’t think you’ve thought through your question. The machine was open in both time periods. The machine was turned off after the information was given. There’s nothing more to happen.
I get what you’re trying to say, but it doesn’t really apply to the scenario you are describing.
I saw a better version of what you are attempting to present: a scientist has a button that transports an object back in time by 5 seconds. An apple is tested successfully, it appears 5 seconds before he pushes the button and when he pushes the button the original disappears. They try it with a live mouse but something goes wrong; when it appears it’s horribly disfigured and this scares the scientist who pulls away from pushing the button. The mouse has already appeared but he will not press the button. Now what happens?
