NexStep, Inc. has petitioned the Supreme Court, questioning a recent Federal Circuit decision that imposes strict limitations on the doctrine of equivalents (DOE) in patent law. In the case against Comcast, the legal argument hinges on whether a patentee must provide 'particularized testimony and linking argument' to prove infringement under the DOE. The case featured a baseball analogy, suggesting that while the accused device requires three button presses for an action, this could still be considered equivalent to the required single action, an interpretation the jury initially favored but the Federal Circuit disputed.
The petition challenges whether the Federal Circuit has imposed overly strict requirements on the doctrine of equivalents, shifting away from Supreme Court precedent.
The expert used a baseball analogy to illustrate how multiple actions can represent a single one, aiming to show equivalence between the two cases.
