The TradeComet complaint looked equally low-merit, so I would have probably ignored it except that TradeComet's counsel was the NYC-based Cadwalader Wickersham & Taft—which also does antitrust work for Microsoft. Those two facts could be completely unrelated, but it's possible that they aren't. First, I can't imagine Cadwalader would jeopardize a lucrative relationship with a Fortune 50 company to take on a low-merit lawsuit for a no-name company. Therefore, either Cadwalader viewed the various antitrust issues as so unrelated that no legal or business conflicts were created—a risky judgment given Microsoft's sensitivity about both Google and antitrust—or Microsoft approved/acquiesced to Cadwalader's representation of TradeComet. Second, Microsoft has been engaged in a multi-year, multi-front effort to harass Google on antitrust issues, and Cadwalader's involvement would be consistent with that campaign.
