Hard to say here. Federal courts have very broad discretion to impose sanctions for violations of their orders, including those authorized by the Federal Rules of Civil Procedure and also those based on their inherent powers. We are, after all, dealing with contempt of a court order, which is very serious. I would say it is likely here that the court would refer this to the State Bar with a request that it be investigated and this would pose quite a risk for one or more of the attorneys that ethical sanctions would be imposed (these can range from private to public censure to suspension to disbarment, though here I don't think the more extreme remedies would apply unless evidence surfaced to show that this was somehow deliberate). A standing order to the firm or to one or more of the attorneys that they would have to do a formal filing in future cases (say, for a period of x years) disclosing this misconduct is also something I could envision here. This would cause large reputational harm to the lawyer(s) involved and would be fitting, doable, and probably appropriate for such a serious violation. Monetary awards/fines are also possible, though I cannot imagine an award that could reflect the actual damage caused to Google - such awards are usually limited to attorneys' fees and costs incurred in obtaining the contempt order. Discovery-related sanctions are also often imposed in live cases (e.g., limiting the use of certain evidence or treating some fact as admitted that is adverse to the party causing the violation or some such thing), but I don't think would apply here. Jailing of an offending party is also used in civil contempt but only as needed to compel compliance with an order (e.g., you will stew in jail until you disclose your non-protected sources for the facts in this story as you have been previously ordered to do) - again, these wouldn't apply here. So, I think the main sanctions would likely involve those hitting the reputations of the attorneys, either in future court proceedings or through State Bar sanctions. These, by the way, are not trivial. No matter how good a lawyer or a firm, being seen as tarnished can cost you clients, job opportunities, etc., not to mention public humiliation and embarrassment (no small thing for prominent lawyers).
