Narrative Opinion Summary
This case involves a patent infringement dispute between iLife Technologies Inc. and Body Media Inc. concerning patents related to systems for evaluating bodily movement in relation to an environment. The primary legal issues revolve around the interpretation of claim terms within five patents, focusing on concepts such as 'environmental tolerance' and 'normal-abnormal accelerative events.' The procedural history includes a joint disputed claim terms chart, a Markman hearing, and subsequent submissions regarding the person of ordinary skill in the art (POSA). The court's rulings emphasize established legal principles for patent claim construction, prioritizing intrinsic evidence such as claim language and specifications over extrinsic sources. The court rejected Body Media's indefiniteness challenges, finding that iLife's proposed constructions were adequately supported by the intrinsic record. Additionally, the court determined that prosecution history did not substantiate Body Media's claim interpretations. The outcome favored iLife, with the court adopting constructions that did not limit claim terms to specific embodiments and rejecting assertions that certain terms were indefinite. The decision reinforces the importance of clear claim language and the specification's role in guiding claim interpretation.

Application: The court is tasked with construing seven disputed claim terms and determining the indefiniteness of nine others. The construction of a patent's claims is a legal question guided by established principles.
Reasoning: The construction of a patent's claims is a legal question, guided by established principles.
Doctrine of Prosecution Disclaimersubscribe to see similar legal issues
Application: The doctrine prevents the patentee from reclaiming meanings disclaimed during prosecution to secure allowance. Body Media's arguments fail to establish a clear and unmistakable disavowal of claim scope.
Reasoning: If an applicant disclaims claim coverage to secure allowance, the doctrine of prosecution disclaimer prevents the patentee from reclaiming those specific meanings through claim interpretation.
Indefiniteness Standardsubscribe to see similar legal issues
Application: To prove indefiniteness, an accused infringer must present clear and convincing evidence showing that the claims do not reasonably inform skilled individuals in the field about the invention's scope.
Reasoning: To prove indefiniteness, an accused infringer must present clear and convincing evidence showing that the claims do not reasonably inform skilled individuals in the field about the invention's scope.
Intrinsic and Extrinsic Evidence in Claim Constructionsubscribe to see similar legal issues
Application: Intrinsic evidence is prioritized over extrinsic when interpreting claims. Extrinsic sources like technical dictionaries or expert testimony can provide context but are less reliable.
Reasoning: The Phillips case emphasized the importance of the intrinsic record over extrinsic evidence when interpreting claims, although extrinsic sources like technical dictionaries or expert testimony can provide context.
Prosecution History and Claim Constructionsubscribe to see similar legal issues
Application: The prosecution history is critical for understanding the inventor's intentions and any limitations made during prosecution. The court finds that the appeal brief does not satisfy the legal standards for prosecution history estoppel or disclaimer.
Reasoning: The prosecution history reflects negotiations with the PTO, it often lacks the clarity of the specification but is still relevant to understanding the inventor's intentions and any limitations made during prosecution.
