In the technology transaction, the relationship between patent holders and competitors (potential infringers) is a typical leader-follower strategy. And the sequence of actions influences the payoff of both sides greatly. Models of "leader-one follower" and "leader-multiple followers" are set up respecti-vely, in order to analyze the strategies and equilibria in situations that a patent holder faces single or multiple competitors. According to the "leader-one follower" model, the corollary "likelihood of entry increases with the penalty" can only exist if the competitor acts preemptively. And results from the "leader-multiple followers" model indicates that the "leading advantage" lies definitely with the holder and that competitors need preemption to maximize their payoff by stimulating the holder to mitigate the litigation.
