This ruling removes a long-standing patent litigation overhang on Amazon's networking services, but the patent is expired and the case was nonprecedential, so the market impact is minimal. No further legal exposure on this patent remains; monitor for any potential Supreme Court cert petition from AlterWAN, though the nonprecedential nature makes that unlikely.

Executive Summary
The Federal Circuit affirmed a stipulated judgment of noninfringement in favor of Amazon in a patent case brought by AlterWAN. The court upheld the district court's claim construction of 'cooperating service provider' as requiring a guarantee of non-blocking bandwidth, which Amazon's services do not meet. This final appellate ruling removes any patent infringement liability risk for Amazon on the asserted claims of the expired '478 patent, ending a multi-year litigation with no damages awarded or injunctive relief imposed.
Court Ruling Details
Key Facts
- The Federal Circuit affirmed the district court's claim constructions for 'cooperating service provider' and 'non-blocking bandwidth' in U.S. Patent No. 8,595,478.
- The ruling affirms a stipulated judgment of noninfringement for Amazon.com, Inc. and Amazon Web Services, Inc.
- The patent at issue ('478 patent) has expired, limiting the forward-looking impact of the ruling.
- No damages were awarded, and no injunction was issued against Amazon.
- The court did not reach AlterWAN's arguments regarding exclusion of its damages expert because the noninfringement ruling was dispositive.
- The opinion is designated as nonprecedential, limiting its value as binding precedent in future cases.
Financial Impact
No damages awarded; no financial exposure from this ruling. The litigation risk on the expired '478 patent is fully resolved.
Risk Factors
- AlterWAN could theoretically petition for certiorari, but the nonprecedential status and unanimous panel (with dissent only on construction reasoning, not outcome) make Supreme Court review highly unlikely.
- Amazon faces other patent litigation risks not addressed in this filing.
