DOJ responds to public comments: The Justice Department filed its response to public comments made about the e-book antitrust case concerning Apple and five major publishers. In the filing, the department rejected the argument that hampering Apple would allow Amazon to take back a monopoly in the e-book industry.

“[The] notion that Amazon will come to exclude competition in e-books and monopolize the industry is highly speculative at best,” Justice wrote. “[Whatever] defendants’ and commenters’ perceived grievances against Amazon or any other firm are, they are no excuse for the conduct remedied by the proposed Final Judgement.”

According to the filing, the United States received 868 comments on the matter, from individuals, companies and from Apple.

Apple, Motorola appeal dismissal: Apple and Motorola are appealing the decisions of Judge Richard Posner, who dismissed their claims of patent infringement, Bloomberg reported. Google’s acquisition of Motorola Mobility got its final nod earlier this year.

The news comes as a judge in Australia made headlines for saying that a patent suit between Apple and Samsung is “ridiculous” and recommends that the companies settle their differences through mediation. Bloomberg reported that the judge asked the lawyers in the case to explain why she shouldn’t send the case to mediation by the end of the week.

Cybersecurity: The Senate is working to push forward with cybersecurity legislation, the Hill reported, with a vote on an amended version of the act sponsored by Sens. Joseph Lieberman (I-Conn.) and Susan Collins (R-Maine) likely to come up Wednesday or Thursday.

Last Thursday night, co-sponsors of the bill agreed to compromise and create legislation that would rely on a private-public partnership to create cybersecurity standards for firms that operate critical infrastructure.

Cramming a ‘significant consumer problem,’ FTC says: The Federal Trade Commission said Monday that “cramming,” or the practice of adding unauthorized charges to wireless phone bills, is a “serious problem for American consumers.”

There has been a lot of movement against the practice on wireline services — last month, Sen. Jay Rockefeller (D-W.V.) proposed a bill that would prohibit the practice. Wireless cramming has also been in the crosshairs of the Federal Communications Commission.

The FTC weighed in on the issue at the request of the FCC, saying that the unauthorized wireless charges are a cause for concern.

“Mobile cramming is likely to continue to grow as cramming schemes expand beyond the landline platform and mobile phones are more commonly used for payments,” the FTC comment said.
