Background
Carolyn Hafeman owns three related patents (U.S. Patent Nos. 10,325,122; 10,789,393; and 9,892,287) directed to methods for displaying return-and-recovery information on lost or stolen computers. The invention causes a screen to appear during or after boot-up showing the owner’s contact details, with the recovery information updatable remotely—without the user needing to take any action beyond powering on the device.
In 2021, Hafeman sued LG Electronics in the Western District of Texas for patent infringement, alleging that LG devices shipped with Google and Microsoft “Find My Device” features infringed her patents. In response, Google and Microsoft filed six inter partes review (IPR) petitions at the Patent Trial and Appeal Board (PTAB), naming LG as a real party in interest. After LG submitted a “Sotera stipulation”—promising not to pursue in district court any invalidity ground raised or raisable in the IPRs—the Board instituted review on all grounds.
In January 2024, the PTAB issued final written decisions finding all challenged claims unpatentable as obvious over a combination of prior art references, principally Jenne (disclosing remote updating of commercial messages on computers during boot-up) and Cohen. The Board also found that Hafeman failed to establish secondary considerations of non-obviousness. Hafeman appealed to the Federal Circuit, raising three main challenges.
The Court’s Holding
The Federal Circuit dismissed in part and affirmed in part, rejecting all three of Hafeman’s arguments.
First, the court dismissed Hafeman’s argument that the Board should have terminated the IPRs after LG violated its Sotera stipulation in the parallel district court litigation. The court held that this challenge was barred from judicial review under 35 U.S.C. § 314(d), which makes IPR institution decisions “final and nonappealable.” Although Hafeman framed her argument as challenging the sufficiency of the Board’s final written decisions under the APA—rather than the institution decision itself—the court found this to be “a distinction without meaningful difference.” Because the Sotera stipulation was a factor in the institution decision, Hafeman’s request to vacate and terminate the IPRs had “institution as its direct, immediate, express subject.” The court cited its recent decisions in Federal Express Corp. v. Qualcomm Inc. and Ethanol Boosting Systems, LLC v. Ford Motor Co. as confirming that recharacterizing an institution challenge as a post-institution procedural complaint does not bypass § 314(d).
Second, the court affirmed the Board’s treatment of the “without assistance by a user” claim limitation. Hafeman argued this phrase meant the user could not provide any assistance whatsoever—including establishing an internet connection—to receive recovery information. The court disagreed, finding from the claim’s plain language that “without assistance by a user” modifies only the act of “initiating or changing return information,” not the unrecited step of establishing an internet connection. The specification reinforced this reading, expressly analogizing the invention to McAfee’s auto-update feature, which contemplates the user going online. Because the prior art reference Jenne disclosed remotely updating displayed information without requiring the user to press a specific key to initiate the change, the Board’s obviousness finding stood.
Third, the court affirmed the Board’s analysis of secondary considerations of non-obviousness under the substantial-evidence standard. Hafeman failed to show a nexus between her commercial product, the “Retriever,” and the patented claims. Industry praise was directed at the Retriever’s unpatented verbal alarm feature, commercial success evidence was never tied to the invention’s merits before the Board, and copying arguments based on Google and Microsoft’s Find My Device programs were forfeited because Hafeman never raised them below.
Key Takeaways
- The Federal Circuit continues to expand the reach of § 314(d)’s bar on judicial review of IPR institution decisions. Even post-institution events like Sotera stipulation violations cannot be used to challenge institution on appeal when the requested relief—termination of the IPR—is functionally a challenge to institution itself.
- Claim terms modifying a specific recited action (here, “initiating or changing” information) do not extend to unrecited preliminary steps (here, establishing an internet connection), even where those steps are practically necessary. Patent holders should draft claims to expressly cover the full scope of user-interaction limitations they intend.
- Secondary-consideration evidence must be tied to the claims, not the specification, and arguments not raised before the PTAB will be deemed forfeited on appeal. Patent owners defending IPRs should present comprehensive nexus evidence and explicitly frame all secondary-consideration arguments during the Board proceeding.
Why It Matters
This decision reinforces the Federal Circuit’s firm stance that § 314(d) is a broad shield against appellate second-guessing of PTAB institution decisions, even when events unfold after institution that arguably undermine the original rationale for proceeding. For IPR petitioners, this is welcome confirmation that institution, once granted, is highly durable. For patent owners, it signals that Sotera stipulations—and any failures by real parties in interest to honor them—are matters for the district court to police, not a lever for unwinding the IPR on appeal.
The claim construction holding is a practical reminder for patent drafters working on software and device-recovery technologies: if the invention’s novelty depends on a hands-free user experience, every step of that experience—including network connectivity—should be expressly claimed. Leaving steps unrecited invites the Board and courts to read them out of the claim scope. For Google, Microsoft, and other device-ecosystem companies, the ruling clears the path on a family of patents that targeted core “Find My Device” functionality used across billions of devices.
