ParkerVision v. Qualcomm: When Rule 54(b) Cannot Create an Immediate Patent Appeal

A district court can label an order “final,” but that label does not necessarily make it appealable. In a precedential decision issued September 30, 2026, the Federal Circuit dismissed ParkerVision, Inc. v. Qualcomm Incorporated because unresolved patent claims meant there was no final judgment within the court’s appellate jurisdiction.

The decision is important for patent litigants trying to appeal a dispositive ruling before every issue in the district court has been resolved. It also clarifies a terminology trap: a “claim” under Federal Rule of Civil Procedure 54(b) means a civil cause of action, not an individual numbered patent claim.

For patent owners and accused infringers, the practical lesson is that appellate strategy should be planned at the patent level—not merely by grouping technically different patent claims and asking the district court to certify one group for immediate appeal.

What happened after the Federal Circuit’s 2024 remand

ParkerVision and Qualcomm have litigated over wireless-communications patents for years. The case that produced the new decision involves U.S. Patent Nos. 7,218,907 and 6,091,940. The asserted claims fell into two broad groups. “Receiver claims” concerned down-conversion of electromagnetic signals from high frequency to low frequency, while “transmitter claims” concerned up-conversion from low frequency to high frequency.

The ’907 patent’s asserted claims were all receiver claims. The ’940 patent included both receiver and transmitter claims.

In an earlier appeal, the Federal Circuit vacated summary judgment of non-infringement and remanded. On remand, the district court conducted claim construction. Based on those constructions, the parties stipulated that Qualcomm’s accused products did not infringe the receiver claims of either patent. The district court then entered partial summary judgment of non-infringement on those receiver claims.

That ruling disposed of every asserted claim of the ’907 patent, but it did not resolve the ’940 patent’s transmitter claims. Instead of proceeding immediately on the transmitter claims, ParkerVision moved for a partial final judgment under Rule 54(b). The district court granted the motion, entered what it called final judgment on the receiver claims, and severed and stayed the transmitter claims while ParkerVision appealed.

The Federal Circuit’s precedential opinion held that the resulting judgment was not final enough to support appellate jurisdiction.

Rule 54(b) uses “claim” differently from patent law

The core problem was linguistic but legally significant. Rule 54(b) allows a district court in a case involving multiple claims for relief to enter final judgment on fewer than all of them if the court expressly determines that there is no just reason for delay.

In ordinary civil procedure, a “claim” in this context is essentially a cause of action. Patent lawyers, however, routinely use the same word to describe the numbered claim language at the end of a patent. Those are different concepts.

The Federal Circuit emphasized that distinction. It explained that the question was not whether particular patent claims had been finally decided. The question was whether an entire civil claim for relief had been finally resolved.

That distinction mattered because the Patent Act generally ties the cause of action to the patent as a whole. Section 281 gives a patentee a civil action for infringement of “his patent,” and Section 271 likewise defines infringement by reference to a patent. The court also relied on precedent explaining that ownership rights attach to patents as a whole and that, ordinarily, each asserted patent supplies one distinct cause of action for infringement.

Why the unresolved ’940 transmitter claims defeated finality

ParkerVision’s first amended complaint pleaded a single count for infringement of the ’940 patent. It did not plead one cause of action for the receiver claims and a separate cause of action for the transmitter claims.

Because the transmitter claims remained unresolved, the civil cause of action for infringement of the ’940 patent remained unresolved too. The Federal Circuit therefore held that Rule 54(b) could not transform the receiver-claim ruling into a final appealable judgment merely because those patent claims had been disposed of.

The court framed its broader rule carefully: “in most if not all instances,” each patent can provide the basis for a single cause of action for infringement, but not more than one. That formulation leaves room for unusual procedural settings, but it squarely rejects the idea that a patent owner may ordinarily divide one patent into separate appellate causes of action by grouping different patent claims.

This matters in complex patent litigation, where different claim groups may turn on different claim constructions, technologies, accused features, experts, or damages theories. Technical separateness does not automatically become procedural separateness for Rule 54(b).

The ’907 patent presented a different problem

ParkerVision argued that even if the ’940 patent was not ready for appeal, the judgment concerning the ’907 patent should be appealable because all asserted claims of that patent had been resolved.

The Federal Circuit still found no jurisdiction. The problem was the district court’s certification. The district court had not been asked to enter final judgment limited to the ’907 patent, and it had not expressly determined that there was no just reason to delay an appeal limited to that patent.

Instead, the district court’s Rule 54(b) analysis grouped the receiver claims from both the ’907 and ’940 patents together. Once the ’940 portion of that certification failed, the appellate court would not reconstruct a narrower certification for the ’907 patent on its own.

That is a useful drafting lesson for litigants seeking a partial final judgment. If one entire patent cause of action has truly been resolved while another remains pending, the Rule 54(b) motion and proposed judgment should identify the final cause of action with precision and should ask the district court to make the required express no-just-reason-for-delay determination as to that specific cause of action.

Rule 54(b) and Section 1292(b) are not interchangeable

ParkerVision also argued that the district court could have certified an interlocutory appeal under 28 U.S.C. § 1292(b). The Federal Circuit rejected that route because Section 1292(b) requires a separate certification and a different analysis.

Section 1292(b) applies when an order involves a controlling question of law, there is substantial ground for difference of opinion, and an immediate appeal may materially advance the ultimate termination of the litigation. The district court had never been asked to make those findings and had not evaluated those statutory factors.

The Federal Circuit would not assume how the district judge might have ruled if a proper Section 1292(b) request had been made. The result reinforces a basic appellate principle: a litigant should select the jurisdictional path before filing the notice of appeal rather than ask the appellate court to retrofit another path after a defect appears.

Tucker Law has written about a related jurisdictional problem in T-Mobile v. KAIFI, where a dispute involving a patent settlement belonged in a regional circuit rather than the Federal Circuit. The common theme is that Federal Circuit jurisdiction depends on the legal character and procedural posture of the case—not simply on the fact that patents are involved.

Severance and a stay did not cure the jurisdiction problem

The district court severed and stayed the unresolved transmitter claims while ParkerVision pursued the receiver-claim appeal. That case-management step did not create appellate jurisdiction.

The Federal Circuit looked to whether there was a genuinely final judgment on a cognizable claim for relief. If the underlying patent cause of action remained unresolved, placing part of the case on hold could not supply the missing finality.

Patent litigants should therefore distinguish between district-court case management and appellate jurisdiction. A stay may make practical sense, and severance can have important procedural consequences, but neither automatically converts a nonfinal patent ruling into a final decision under 28 U.S.C. § 1295(a)(1).

What patent litigants should check before pursuing an immediate appeal

Start with the causes of action, not the patent claim chart. Identify which patent-based counts are fully resolved and which remain pending. If any asserted claims of the same patent remain live, ParkerVision creates a serious obstacle to Rule 54(b) certification of only the resolved patent claims.

Draft the certification narrowly. If an entire patent cause of action has been resolved, the Rule 54(b) motion should focus on that patent and should expressly request the no-just-reason-for-delay finding required by the rule.

Evaluate Section 1292(b) independently. If the real objective is review of a controlling legal question before final judgment, Section 1292(b) may be the more appropriate mechanism, but its statutory prerequisites must be addressed in the district court.

Consider whether waiting is strategically better. Immediate appellate review can save substantial resources when a threshold ruling controls the case, but an unsuccessful jurisdictional attempt creates delay and expense of its own. Parties should compare the likely timing of trial, remaining discovery, claim-construction issues, and the probability that the Federal Circuit will accept jurisdiction.

Those questions should be integrated into overall patent strategy early, particularly in multi-patent cases where different patents or claim groups may reach dispositive rulings at different times.

The court also refused to reassign the case

ParkerVision asked the Federal Circuit to direct that the case be reassigned to a different district judge on remand. Because the appeal arose from the Middle District of Florida, the Federal Circuit applied Eleventh Circuit law to that request.

The panel acknowledged ParkerVision’s concerns about some of the district judge’s statements but concluded that reassignment was not warranted. Among other things, the court noted that the judge had followed the Federal Circuit’s earlier instruction to conduct claim construction and that transferring a long-running, technically complex case to a new judge would create substantial duplication and waste.

The court therefore dismissed the appeal for lack of jurisdiction and denied reassignment. It did not decide the merits of the receiver-claim construction or non-infringement ruling in the dismissed appeal.

The practical takeaway from ParkerVision v. Qualcomm

ParkerVision is a warning against treating individual patent claims as though they were automatically separate “claims for relief” under Rule 54(b). A patent may contain many numbered claims, and those claims may involve distinct technology, but the civil cause of action ordinarily runs with the patent as a whole.

For parties seeking an immediate appeal, the safer approach is to identify exactly what cause of action has been fully resolved, obtain an express and properly tailored Rule 54(b) determination when available, and separately evaluate whether Section 1292(b) offers another route. For parties opposing an interlocutory appeal, the same questions can reveal a jurisdictional defect before substantial appellate resources are spent.
