I have three brief comments on the opinion:
1. This is not a surprising result given the oral argument. The only surprise here is that the "entire product" rule had been in place so long, essentially unchallenged, such that this is a new way to look at damages.
2. One reason why the old rule was in place a long time is that it is difficult to square this opinion with the historical context of section 289 (or rather, its predecessor). The carpet in the Dobson case (which had awarded only nominal damages) had a design on the front, but also had an unpatented backing, etc. Although there were at least two components, no one at the time Congress passed the law thought for a second that the profits for each component should be considered separately. Indeed, that's what the court had done in Dobson, finding that the design added nothing to the profits -- the whole reason Congress passed a statute in the first place. This context is why (as I've written before), I've always been torn about this case. As a matter of statutory interpretation, the Court is surely right. But if that's true, then the statute has been misapplied literally since day one - and that doesn't sit well with me.
3. This is a "live by the sword, die by the sword" opinion. If patentees want to claim articles of manufacture that are less than whole products, then they have to accept that articles of manufacture for damages are less than whole products. The court cites In re Zahn (an often maligned case) approvingly. In Zahn, the patentee claimed the shank of a drill bit but not the bit itself:
Now comes the difficult/fun (in the eye of the beholder) part: how do we calculate profits on an infringing drill bit? The patentee argues that drill bits are fungible, so that 100% of the profits must be assigned to the shank "article of manufacture." The infringer argues that people buy drill bits to drill, not to look at, so that 100% of the profits must be assigned to the bit "article of manufacture." If the infringer wins, even substantially, then we are back in the pre-289 world of Dobson. That can't be right. But if the patentee wins, it means that the Supreme Court's opinion means nothing.
I'm sure that some happy medium will be determined by experts, judges, and juries, but this is an area that is not going to be getting clarity any time soon.
