Newegg's legal counsel, Lee Cheng, successfully convinced his bosses that they might save money by fighting patent extortionists instead of paying them. They had an early high profile case, and won, and then won several more. (Also lost a couple, if I remember right.)

Lee furthermore pursued a strategy of trying to win by invalidating the patent. Newegg got enough of a reputation for this that patent trolls would mass-file a lawsuit, realize that they had included Newegg in the lawsuit, and withdraw the suit. So then Newegg started a strategy of chasing down any patent troll dumb enough to file a suit against Newegg, and aggressively sue them in retaliation -- again, seeking to invalidate the patent (https://arstechnica.com/tech-policy/2016/01/newegg-sues-pate...).

Cheng and Newegg eventually went their separate ways, and I haven't heard much from either one since. But, for a while, Newegg was in the tech news every few months for doing real damage to another patent extortion outfit, and it was glorious.
