- DHMO 10y agoThe rocket-propelled over-the-top one isn't patented, though. https://www.youtube.com/watch?v=HrrorPT8jsM&feature=youtu.be&t=45s https://www.youtube.com/watch?v=HrrorPT8jsM&feature=youtu.be...
- amelius 10y agoWell if the original patent was defined in terms of an abstract force, like it should have been, then the rocket-propelled one is patented too. All advice I've heard so far about filing patents is to keep things as abstract as possible.
