PatentlyO (Dennis Crouch) does his usual excellent job of sorting and listing and linking to the briefs filed in eBay v. MercExchange and summarizing some of the major ones. He notes: "Because this issue is so fundamentally important to patent law, eBay v. MercExchange will likely be the most important patent case for the past decade."

Yesterday, the Solicitor General filed a motion for leave to argue as amicus and for divided argument. This is a big deal, because, while the SG supports MercExchange, technically, in fact its position on the proper legal rule is that of eBay's supporters -- that a district court has the power to weigh equitable factors in deciding whether to grant an injunction, that the Federal Circuit unfortunately forgot to articulate this standard, and that while a presumption in favor of an injunction might exist, its issuance is by no means automatic. (See the Summary of Argument at pp. 8-10 of the SG's brief.) However, the SG thinks eBay should lose this case, so the Petitioner is unlikely to be happy even if its amici supporters are ecstatic.

Crouch agrees:

[The SG's] position goes along with my own thoughts that the Supreme Court will hold that a court should weigh the pros and cons of an injunction before shutting down an infringer, but that there will still be a strong presumption that an injunction will grant — especially when the infringement is willful.
