Joe Mullin, writing for Ars Technica:

A patent-holding company called Minero Digital seeks to exact royalty payments on a wide range of USB hubs, suing more than two dozen retailers and manufacturers last year. But the “non-practicing entity” dropped its East Texas lawsuit against Newegg subsidiary Rosewill within days of getting a call from the company’s lawyer. It’s not going to be easy for Minero and its president, Texas lawyer Daniel Perez, to walk away, though. Yesterday, Newegg filed its own lawsuit (PDF) against Minero in Los Angeles federal court, asking a judge to rule that Rosewill products do not infringe Minero’s patent.

And:

Beyond the possibility of being sued again, Cheng noted that Minero continues to litigate against other retailers that sell Rosewill-branded products and that Newegg may have defense obligations to those other companies. Minero continues to press its case against more than 20 companies, with the defendants including Office Depot, Walmart, and Amazon—three big retailers that sell Rosewill products.

Newegg’s lawsuit asks only for a judicial ruling of non-infringement, not money damages

Not only does Newegg sell a nice line of tech products and provide excellent customer service, they also stick up for themselves. It would have been easy for them to pay Minero to go away. But not only did they stand up to the bully, they are now countersuing to prevent Minero from collecting from anyone else on this patent claim.
