Guest post by Rick Sanders of TechdirtA few weeks ago, we wrote about the 9th Circuit overturning the district court's ruling in a copyright case questioning whether the song "Stairway to Heaven" had infringed on the song "Taurus" by Spirit. We were less than pleased with this result, as we felt the original ruling was correct. Copyright lawyer Rick Sanders disagreed with part of our analysis and made some really great points in a two part blog post series, which he's graciously allowed us to repost in slightly edited form here. Part II will be published tomorrow.Yes, the new 9th Circuit surprising reversal of the jury verdict looks like "Blurred Lines" all over again — only in reverse. Whereas in "Blurred Lines," the jury reached the "wrong" conclusion, and the Ninth Circuit refused to fix the jury's mistake, here it looks like the jury reached the "right" conclusion," and the Ninth Circuit is screwing up the jury's work. Techdirt all but said so, in an article 9th Cir Never Misses a Chance to Mess Up Copyright Law: Reopens Led Zeppelin 'Stairway to Heaven' Case.I'm pleased to report that, far from taking this opportunity to further screw up copyright law, as Techdirt fears, the panel of judges is attempting to improve copyright law by replacing the Ninth Circuit's (very bad) framework for copyright infringement with a much better one. Indeed, the "Stairway to Heaven" opinion may be seen as a rebuke to the "Blurred Lines" opinion. The pity is that Led Zeppelin must bear this burden by having to do the trial all over again.The reason the "Stairway to Heaven" has to do with our old, misunderstood frenemy, the "Inverse-Ratio rule," which is only tangentially related to why the case is being sent back for a second trial. I blogged extensively about the "inverse-ratio" rule in connection with the "Blurred Lines" case, and how the Ninth Circuit (correctly) amended its opinion to excise (its terrible) discussion of the rule. But here's the deal: the inverse-ratio rule provides that the more similarity there is between the two works, the less proof of access you need, and vice-versa. It is highly beneficial when applied to the right legal framework for copyright. It is a perverse disaster when applied to the wrong legal framework.Two Legal Frameworks for Copyright Infringement
Generally, there are two leading legal frameworks for determining when someone has infringed copyright:- Plaintiff must prove (a) defendant's access to the copyrighted work, plus (b) "substantial similarity" between the two works. This framework is used by the majority of courts, so we'll call it the "Majority Framework." It is also a bad framework.
- Plaintiff must prove (a) "copying" and (b) "unlawful appropriation." To prove "copying," the plaintiff must prove (1) access and (2) "probative similarity." "Unlawful appropriation" is pretty much the same thing as "substantial similarity," but the different term is used to avoid confusion with "probative similarity" (and is also more accurate). This framework is preferred by scholars and is used by one half of the Second Circuit, so we'll call this the "Preferred Framework."
The Ninth Circuit Uses a Weird Hybrid Legal Framework for Copyright Infringement, but "Stairway to Heaven" Opinion Might Fix That.
Which of these two frameworks does the Ninth Circuit use? Neither, of course. This is the Ninth Circuit we're talking about. Its framework looks like a combination of two. On the one hand, it follows the Majority Framework by requiring proof of access (instead of copying) and "substantial similarity." But then is splits the inquiry into "substantial similarity" into two tests, both of which must be proven: the "extrinsic test" and the "intrinsic test." The extrinsic test is meant to be "objective." The jury is permitted to consider both protectable and non-protectable elements, to dissect the elements and compare those, and to consider expert opinion. You know what that is? Probative similarity, but here's it's pressed into the service of substantial similarity and has been separated from the inquiry into access.The intrinsic test is just the normal test for "substantial similarity"/"unlawful appropriation" that every other court uses. Calling it a "test" is overstating it: it's more like the jury's gut instinct, based on the "total concept and feel" of the works. Sorry, but no one has come up with a better way of formulating the test, or how "total concept and feel" works when both protectable and non-protectable elements have been taken. To be fair to the Ninth Circuit, the distinction between intrinsic and extrinsic evidence was innovative at the time and served as an important stepping stone to the preferred legal framework. Alas, the way precedent works, the Ninth Circuit has been stuck at this half-way point for decades. It should go without saying that the application of the "inverse-square" rule to the Ninth Circuit's framework can be ugly.But that's what makes the court's opinion in the "Stairway to Heaven" case so exciting. The court straight up endorses the Preferred Framework, even using the preferred terminology:Whether Defendants copied protected expression contains two separate and distinct components: "copying" and "unlawful appropriation." A plaintiff must be able to demonstrate that a defendant copied his work, as independent creation is a complete defense to copyright infringement. In cases such as this one where there is no direct evidence of copying, the plaintiff can attempt to prove it circumstantially by showing that the defendant had access to the plaintiff's work and that the two works share similarities probative of copying. When a high degree of access is shown, a lower amount of similarity is needed to prove copying. To prove copying, the similarities between the two works need not be extensive, and they need not involve protected elements of the plaintiff's work. They just need to be similarities one would not expect to arise if the two works had been created independently.It then tackles the plaintiffs' argument about the missing "inverse-ratio" rule. I'll bet the plaintiffs were wanting an "inverse-ratio" instruction that told the jury to weigh access against substantial similarity. If so, the Ninth Circuit had some bad news for it: the "inverse-ratio" applies only to copying, not to substantial similarity.This [inverse ratio] rule assists only in proving copying, not in proving unlawful appropriation. Even if a plaintiff proves that a defendant copied his work, the plaintiff must still show that the copying amounts to unlawful appropriation. The showing of substantial similarity necessary to prove unlawful appropriation does not vary with the degree of access the plaintiff has shown.The court then went on to suggest strongly to the trial court that an "inverse ratio" rule might be a really good idea, in a case where there's proof of access.But what about that intrinsic-extrinsic distinction? Surely, it's no longer relevant, right? Well, I guess the Ninth Circuit wasn't quite prepared to get that radical. With a little hocus-pocus, it sort of re-purposed the distinction in the service of substantial similarity/unlawful appropriation. Now, instead of being objective and subjective, it's about making sure you have both evidence of appropriation of protected elements and that gut-feeling. OK, whatever—that might actually be an improvement, since its one way to reconcile "total concept and feel" with a need to filter out non-protectable elements.Emphasis on "Might"
The fight's not over. When a Circuit court takes up an appeal, it assigns a panel of three of its judges. In theory, a panel can't overrule an earlier panel—for that to happen, you need the entire court, or in the 9th Circuit a larger panel of judges, (called "en banc") to take up the case, which is rare (but not unheard of). Right now, later panels have the option of picking which framework they want to use: follow "Blurred Lines'" traditional Ninth Circuit framework, or adopt "Stairway to Heaven's" newfangled Preferred Framework. Obviously, parties are going to pick the one that works best for them. We might end up with an internally-split circuit (which is essentially the current situation with the Second Circuit). Of course, the Supreme Court to step in and fix it, but let's be serious. Indeed, it is almost scandalous that, for decades, there have been multiple frameworks for a concept CENTRAL to copyright law, and the Supreme Court has never expressed interest in the subject.Now, as it happens, the court's discussion of the "inverse-ratio" rule, and its related description of the Preferred Framework, is not what caused the court to vacate the jury verdict and send the case back down for a second trial. I'll explain the twin brain farts that caused that disaster in a subsequent post.Rick Sanders is a trademark, trade secrets and copyright litigator and a founding partner of Aaron & Sanders, PLLC.
