Mark - During the 03-04 time frame, it was very clear to most reasonably intelligent people that Huawei was purposefully copying Cisco in every respect: code, marketing and naming convention. The routers even looked very similar too add insult to injury. While most companies use patent litigation as a sword to stifle innovation or use the expense/distraction of legal action to distract competitors, Cisco does not. This particular case seemed to follow the standard Chinese M.O. of copy and produce at a lower labor rate. I commend Cisco for proper defense of their IP as Cisco has the right balance of fairness - mirrors the overarching culture!
