Federal Circuit Review | March 2026

Why It Matters

These rulings tighten patent‑eligibility standards, protect privileged communications, and reinforce procedural safeguards, reshaping litigation strategy for tech and IP practitioners.

Key Takeaways

• Federal Circuit deemed software claims abstract, vacating $185M verdict
• Conflict does not automatically end attorney‑client privilege, contempt reversed
• Means‑plus‑function valid if structure performs claimed function only
• Voluntary dismissal cannot reset 30‑day stay deadline

Pulse Analysis

The Federal Circuit's recent Alice analysis signals a stricter approach to software patent eligibility. By emphasizing that claim language, not speculative improvements in the specification, must anchor eligibility, the court sent a clear message to patentees: abstract ideas remain vulnerable unless the claims themselves articulate concrete technical steps. This decision follows a wave of post‑Alice rulings that have eroded the value of broad antivirus and security patents, prompting companies to revisit drafting practices and consider alternative protection strategies such as trade secrets or narrower claim sets.

In a separate but equally consequential opinion, the court reinforced the durability of attorney‑client privilege even when a lawyer faces a conflict of interest. The ruling underscores that privilege is a substantive right that does not dissolve automatically; courts must assess whether the underlying relationship has been terminated before compelling disclosure. Law firms handling multi‑client matters must therefore implement rigorous conflict‑screening protocols and maintain clear documentation of representation status to avoid costly contempt sanctions and fee awards.

The decisions on means‑plus‑function claim construction and procedural timing further tighten the procedural landscape for IP litigants. Recognizing that a disclosed structure may satisfy a means‑plus‑function limitation despite ancillary capabilities simplifies claim construction and reduces the risk of indefiniteness findings. Meanwhile, the affirmation that a voluntary dismissal cannot be used to sidestep the 30‑day mandatory‑stay window preserves the statutory balance between trade‑secret enforcement and patent disputes. Together, these rulings provide clearer boundaries for patent drafting, litigation tactics, and procedural compliance, urging practitioners to align their strategies with the court's heightened emphasis on claim precision and statutory deadlines.
