Patent eligibility decisions are not new. Courts have grappled with what can and cannot be patented for years, especially in the technology and software spaces. A recent decision from the U.S. Court of Appeals for the Federal Circuit, U.S. Patent No. 7,679,637 LLC v. Google LLC, builds on the previous framework, affirming a district court’s holding that the asserted patent is invalid. In doing so, the court articulated the standard in a potentially new way, holding that patent claims “need not explicitly recite” a technological improvement to be nonabstract and encouraging courts to review the specification and determine whether an improvement is “embodied in the claims.”
The patent at issue relates to web conferencing systems with “time-shifting capabilities,” allowing participants to watch streaming data live, on a delay, or after completion.
The patentee sued for infringement in the Western District of Washington. The defendant moved to dismiss, arguing that the patent was directed to ineligible subject matter and invalid. Judge John H. Chun granted the motion, holding that the claims were directed to an abstract idea and lacked an inventive concept.
The Federal Circuit applied the two-step Alice framework and came to the following conclusions:
The Federal Circuit’s decision is noteworthy not because of its conclusion but because of the statements it made to get there. For years, courts have held that patent eligibility depends on what is claimed. Under that framework, a patent might be invalid if the specification discusses improvements over the prior art, but the claims are broadly written and do not capture those improvements. Here, the court wrote that while the eligibility question focuses on the claim language, “the claim itself need not explicitly recite the improvement.” The court wrote that its precedent supports a variety of approaches, including looking to the written description to understand the problem addressed, what the patent describes as the invention, and whether any technological improvement is “embodied” in the claims and described in the specification.
Notably, this articulation of the legal standard was not directly relevant to the court’s analysis of the patent at issue. The court’s language also tracks a “reminder” issued by the USPTO in August 2025, stating that (1) the “claim itself does not need to explicitly recite the improvement described in the specification” and (2) patent examiners should “consult the specification to determine whether the disclosed invention improves technology or a technical field, and evaluate the claim to ensure it reflects the disclosed improvement.”
