Background
ClearPlay, Inc. sued Dish Network L.L.C. and Echostar Technologies LLC, alleging that the AutoHop commercial-skipping feature infringed two patents: United States Patent No. 7,577,970 and United States Patent No. 6,898,799. The patents cover methods for filtering multimedia content by dividing programs into navigation objects that define start positions, stop positions, and specific filtering actions. A jury initially found infringement and awarded damages, but the district court granted the defendants’ motion for judgment as a matter of law, concluding the evidence did not support the verdict. ClearPlay appealed.
The court’s reasoning
The court reviewed the claim constructions and found no error in the district court’s application of the jury instructions. Regarding the ninety-seven zero patent, the court held that AutoHop did not directly disable navigation objects because it checked global conditions of whether the feature was enabled and whether the device was in play mode, rather than checking each individual segment for direct disablement. Regarding the seven hundred ninety-nine patent, the court found that the announcement files did not contain individual configuration identifiers and filtering actions within each navigation object as required. Instead, the files used a single configuration identifier for the entire file, which the court determined did not meet the claim limitation requiring each object to contain its own identifier. The court also rejected the doctrine of equivalents argument, stating that the defendant’s method of sharing elements across multiple objects was not substantially the same as the patent’s single-object approach.
Those background conditions, rather than the direct disablement of particular segments, determine AutoHop’s behavior, and for that reason, AutoHop does not directly disable navigation objects.

What it means going forward
The decision reinforces the requirement that patent claims for filtering methods must be strictly adhered to in software implementation, particularly regarding the structural containment of identifiers and the directness of disabling actions. It limits the scope of patent protection for commercial-skipping technologies that rely on global state checks or shared configuration data rather than per-segment object definitions.
