Thanks for playing!
Yes, that was intentional due to some complexity compromises:
Each patent-invention pair has for each of the three main arguments (color, shape, function) a probability to win. We defined each manually. So 5 patents times 6 inventions/patent = 30 patent-invention pairs. 30 pairs times 3 arguments = 90 probabilities which need to be defined/balanced manually.
Opening up the possibility to infringe any product with any patent would be a combinatorical nightmare:
Each of the 5 patents could sue all 36 inventions with 3 arguments each: 540 probability values.
