Optis Cellular Technology v. Apple Inc.: Federal Circuit Orders New Trial on Infringement and Damages Due to Unanimity Violation and Improper Evidence

The Federal Circuit’s June 16, 2025, decision in Optis Cellular Technology, LLC v. Apple Inc., Nos. 2022-1904, 2022-1925, vacates a $300 million damages judgment in a high-stakes standard-essential patent (SEP) case and mandates a new trial on both infringement and damages. The court found that the Eastern District of Texas violated Apple’s constitutional right to a unanimous jury verdict and improperly admitted prejudicial evidence, including a large Apple-Qualcomm settlement. The ruling also carries broader implications for the treatment of abstract claims under § 101 and functional claim limitations under § 112 ¶ 6.


Key Takeaway

The Federal Circuit vacated both the infringement and damages verdicts because the jury verdict form failed to ensure unanimity on specific claims, and because the district court improperly admitted a high-dollar Apple-Qualcomm settlement agreement. The court also held two of the asserted claims invalid under § 101, reversed a § 112 ¶ 6 ruling, and rejected the patentee’s request to reinstate a previously set-aside $506 million award.


Background

Optis, asserting a suite of five LTE standard-essential patents, sued Apple in the Eastern District of Texas in 2019. After an initial trial in 2020, the jury awarded Optis $506.2 million in damages, finding infringement and willfulness. However, the trial court granted Apple a new trial on damages due to improper exclusion of FRAND evidence. A second trial in 2021 resulted in a $300 million lump-sum verdict.

Apple appealed, challenging liability, damages, claim construction, and admissibility of certain evidence. Optis cross-appealed, seeking reinstatement of the original damages verdict.


The Verdict Form and Jury Unanimity Violation

The Federal Circuit held that the district court erred by using a single verdict question that asked whether Apple infringed “ANY of the asserted claims” without distinguishing between the five asserted patents. This structure permitted a finding of liability even if jurors disagreed on which patents were infringed, violating Apple’s right to a unanimous verdict under the Seventh Amendment and Federal Rule of Civil Procedure 48(b):

“The verdict form instructed the jury to find Apple liable for infringement regardless of whether all jurors agreed that Apple was infringing the same patent.” (Slip op. at 15)

Despite the parties’ joint request for patent-by-patent questions, the district court rejected that format. The Federal Circuit deemed this a clear legal error warranting vacatur of the liability judgment and a new trial.


Damages Verdict Also Vacated

Because liability was vacated, the court also vacated the $300 million damages verdict. Notably, the district court had instructed the jury to assume all five patents were infringed for purposes of damages—an instruction that now lacks any valid liability finding to support it.

Further, the court held that the district court abused its discretion under FRE 403 by admitting a high-value Apple-Qualcomm settlement agreement and allowing Optis’s expert to rely on it:

“[T]he probative value of the Apple-Qualcomm settlement agreement and Mr. Kennedy’s testimony concerning the same is substantially outweighed by the risk of unfair prejudice.” (Slip op. at 36)

This agreement, which settled global disputes unrelated to the patents-in-suit, was deemed minimally probative and highly prejudicial.


Patent Eligibility Under § 101

The court reversed the district court’s denial of Apple’s § 101 motion on claims 6 and 7 of U.S. Patent No. 8,019,332, finding them directed to an abstract mathematical formula:

“We conclude that the claims are directed to the abstract idea—a mathematical formula.” (Slip op. at 24)

Charles Gideon Korrell notes that the Federal Circuit found the claims failed Alice step one and remanded for further proceedings on step two.


Means-Plus-Function and § 112 ¶ 6

In another reversal, the Federal Circuit held that the term “selecting unit” in claim 1 of U.S. Patent No. 8,411,557 invoked § 112 ¶ 6. It found “unit” to be a nonce term that fails to connote sufficient structure:

“‘Selecting unit’ in the claim at issue here invokes § 112 ¶ 6.” (Slip op. at 31)

The district court had relied on a prior Eastern District ruling, but the Federal Circuit found that opinion unpersuasive, particularly in light of Optis’s own assertion that the “unit” could be implemented in hardware or software. The matter was remanded to determine if the specification provides sufficient structure.


Claim Construction Affirmed

The court affirmed the construction of a key term in claim 8 of U.S. Patent No. 8,102,833, rejecting Apple’s argument that the mapping of ACK/NACK control signals required a specific start position.


Optis’s Cross-Appeal Rejected

Optis had sought reinstatement of the original $506.2 million award from the first trial, but the Federal Circuit dismissed the cross-appeal, concluding that:

“[T]he first damages judgment presented the same verdict form issue… and thus cannot be reinstated.” (Slip op. at 36)


Practical Implications

This decision reinforces several critical points for SEP litigation and patent damages trials:

  1. Verdict Form Precision Matters: Patent plaintiffs must ensure verdict forms distinguish each asserted patent or claim to avoid violating the defendant’s right to unanimity.
  2. Evidence of Other Settlements Is Risky: Courts will scrutinize the use of large dollar-value settlements, especially when they involve different technologies or were driven by non-comparable litigation pressure.
  3. FRAND Damages Must Align with Liability: Damages awards must correspond to actual findings of infringement, particularly in FRAND cases.
  4. § 101 and § 112 Scrutiny Continues: The court’s reversals on patent eligibility and means-plus-function interpretation signal a continued willingness to invalidate improperly drafted claims—even in complex SEP disputes.

Charles Gideon Korrell notes that the Federal Circuit’s opinion emphasizes procedural fairness as much as substantive patent doctrine. Charles Gideon Korrell also observes that the court’s insistence on clarity in verdict forms may drive future litigants to pay closer attention to the architecture of jury questions.


Conclusion

The Federal Circuit’s decision in Optis v. Apple is a comprehensive rebuke of multiple aspects of the trial court’s handling of a major SEP case. By ordering a new trial on both liability and damages and reversing several key legal rulings, the opinion sets important precedent for how SEP litigation should be conducted and how damages should be assessed.
