Background
Interval Licensing LLC — a patent holding company backed by Paul Allen (co-founder of Microsoft) — held U.S. Patent No. 6,788,314, which describes an “attention manager” system that presents information to a user by exploiting “unused capacity” in a display device. The patent claimed a system that would show content either when the user was not actively engaged with the display, or in an area of the screen not used by the user’s primary activity (a kind of ambient or peripheral display).
Interval Licensing sued AOL, Apple, Google, and Yahoo for infringement. The defendants challenged the claims under § 101. The Federal Circuit had previously addressed indefiniteness issues in this case in an earlier appeal; on this appeal it tackled the eligibility question.
The Court’s Holding
The Federal Circuit affirmed invalidity under § 101. The court held the claims were directed to the abstract idea of displaying two information sets on a screen simultaneously without one interfering with the other — an abstract concept without any limitation on how to achieve it technically. The critical flaw the court identified was that the patent claimed a result without specifying any particular technical means for achieving that result. The term “attention manager” was construed broadly enough that it encompassed any technique for achieving the desired non-interfering display, without tying the claim to a specific technical approach.
At step two, the court found no inventive concept. The claimed system used conventional computer components and display technology to achieve a result that was not technically novel. The court distinguished patents that claim a specific technical implementation of an improvement from those that broadly claim a desired result — the latter are more likely to be abstract ideas.
Key Takeaways
- Patent claims that recite a desired result — “display content without interfering with primary content” — without specifying the technical means for achieving it are vulnerable to § 101 invalidation as directed to abstract ideas.
- Broadly construed functional terms in claims (like “attention manager”) that encompass any and all means of achieving a result, without specifying a particular mechanism, may be treated as directed to an abstract idea rather than a specific technical solution.
- Judge Plager’s partial dissent lamented the state of § 101 law, arguing it had become so unpredictable as to be nearly unworkable — an early judicial critique that would intensify in coming years.
- The “result-claiming” principle from Interval Licensing has been widely applied: claims that define an invention by what it does rather than how it does it face heightened § 101 risk.
Why It Matters
Interval Licensing introduced and clarified an important concept in post-Alice § 101 jurisprudence: the distinction between claiming a specific technical solution and claiming a desired result. This distinction has become one of the Federal Circuit’s key tools for sorting patent-eligible inventions from abstract ideas. A patent that says, in effect, “do X (a goal)” without explaining “how to technically achieve X” risks invalidity, even if X was a genuinely new idea.
The decision also foreshadowed growing judicial concern about § 101’s doctrinal clarity. Judge Plager’s dissent was an early and notable call for the court to acknowledge the law’s incoherence. His concerns were echoed by many more judges and commentators in the years that followed, contributing to the ongoing legislative debate over § 101 reform. For software patent drafters, the case remains a strong reminder to draft claims with specific technical steps, not just functional outcomes.
