Hafeman v. Google LLC — Federal Circuit Affirms PTAB Ruling That “Find My Device” Patents Are Unpatentable

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 information on a lost or stolen computer’s screen during or after boot-up. The patents describe a system where a recovery screen automatically appears before or alongside the login screen, showing the owner’s contact information to help facilitate the computer’s return. A key feature is the ability to remotely update this return information “without assistance by a user with the computer.”

Hafeman sued LG Electronics in the Western District of Texas for infringement, alleging that LG phones, tablets, and laptops sold with pre-loaded Google and Microsoft “Find My Device” features infringed her patents. Google and Microsoft then filed six inter partes review (IPR) petitions at the Patent Trial and Appeal Board (PTAB), naming LG as a real party in interest. LG served a “Sotera stipulation” in the district court litigation, promising not to pursue any ground in the district case that could have been raised in the IPRs. The PTAB instituted review on all grounds, and ultimately found all challenged claims unpatentable as obvious over the combination of Jenne (a prior art reference disclosing remotely updated commercial messages during computer boot-up) and Cohen.

The Court’s Holding

The Federal Circuit dismissed in part and affirmed in part, upholding the PTAB’s unpatentability findings across all three patents.

Sotera stipulation challenge dismissed. Hafeman argued that the Board should have terminated the IPR proceedings after LG violated its Sotera stipulation in the parallel district court case. The court held this challenge was barred by 35 U.S.C. § 314(d), which makes IPR institution decisions “final and nonappealable.” Citing Thryv, Inc. v. Click-To-Call Technologies and its own recent decision in Federal Express Corp. v. Qualcomm Inc., the court explained that regardless of how Hafeman framed her argument — as a challenge to the Board’s final written decisions rather than to institution — the substance of her claim “still boil[ed] down to a challenge over whether there should have been institution at all.”

Claim construction affirmed. The court affirmed the Board’s reading of the “without assistance by a user” claim limitation. Hafeman contended this phrase meant the user could not provide any assistance whatsoever (beyond powering on the device), including establishing an internet connection. The court disagreed, holding that “without assistance by a user” modifies only the action of “initiating or changing return information” — not the unrecited step of establishing an internet connection. The specification’s own description of the invention as analogous to McAfee’s anti-virus auto-update feature, which activates “every time you go on-line,” confirmed that the patent contemplated user-initiated internet connections.

Secondary considerations rejected. The Board’s finding of no nexus between Hafeman’s commercial product (the “Retriever”) and the claimed invention was supported by substantial evidence. Industry praise focused on the Retriever’s unpatented verbal alarm feature, and Hafeman’s evidence of commercial success consisted only of website visitor counts without connecting them to the patented features.

Key Takeaways

• § 314(d) bars creative repackaging of institution challenges. Even when framed as an APA-adequacy challenge to a final written decision, an argument that seeks to unwind IPR proceedings based on the circumstances that led to institution remains unreviewable under § 314(d).
• Sotera stipulation violations are for the district court, not the Federal Circuit. Patent owners who encounter a Sotera stipulation violation must seek relief in the parallel district court proceeding, not by asking the PTAB or Federal Circuit to terminate the IPR.
• Claim limitations must be read in context. A limitation modifying one action in a method claim does not automatically extend to other unrecited preparatory steps, even if those steps are practically necessary for the method to function.
• Nexus for secondary considerations requires connection to claimed features, not just the specification. A product referenced repeatedly in the specification still needs to embody the claimed features — or the patentee must independently show the secondary-consideration evidence results from the invention’s unique characteristics.

Why It Matters

This decision reinforces the Federal Circuit’s increasingly firm stance that § 314(d) bars appellate review of any challenge that, at its core, attacks the Board’s decision to institute an IPR. For patent owners, the practical lesson is stark: if the basis for challenging an IPR is connected to the institution decision — even if the triggering event occurred after institution — the Federal Circuit will not hear it. This is particularly significant for Sotera stipulation disputes, which are becoming more common as petitioners use them strategically to overcome discretionary denial of IPR petitions.

The claim construction holding also carries practical weight for software patent drafters. The court’s narrow reading of “without assistance” as modifying only the immediately recited step — not preparatory infrastructure like establishing an internet connection — suggests that applicants who want to claim truly automated, zero-user-intervention processes must explicitly exclude user involvement at every step, not just the core action.
