US federal appeals court

The US Court of Appeals for the Federal Circuit has affirmed a lower court's dismissal of patents covering internet advertising technology owned by a party challenging Google. The court found the claims ineligible under Section 101 of the Patent Act, which governs whether inventions are patentable subject matter. The decision is being closely watched by intellectual property practitioners, as it adds to the line of Federal Circuit rulings limiting software and business-method patents in the digital advertising space.

Prediction market operator Kalshi has lost a ruling at the appeals court level concerning whether state regulators can oversee its prediction markets. The decision means states may retain authority to regulate or restrict certain event contracts, a setback for Kalshi's argument that federal law preempts state oversight of its business. The ruling is likely to shape ongoing disputes between prediction market platforms and state gaming and securities regulators.
