Interpreting Patent Claims: Patent Drafters Say What They Mean, But Do They Mean What They Say?
What exactly does it mean to interpret claims “in light” of the specification? Do the descriptions and examples in a patent specification affect the interpretation of the patent's claims where there is no express statement that a specialized definition is being given to claim terms? Absent a specific glossary section, is it even necessary to read the specification or should the public be free to read and interpret the claims in a vacuum? Within 4 days, two separate panels of the Federal Circuit delivered seemingly conflicting answers to these questions, highlighting a growing rift regarding the significance of the specification and prosecution history to claim interpretation.
Seemingly relegating the patent specification to second-class status, the panel in Housey Pharm., Inc. v. Astrazeneca UK Ltd., 364 F.3d 1348 (Fed. Cir. 2004), began its analysis by stating that there is a “heavy presumption” that the language in a claim “carries its ordinary and customary meaning.” Based on the court's approach, this ordinary definition can be determined by looking in dictionaries. This panel stated that in order to overcome this “heavy presumption” that the dictionary definition is the controlling interpretation, the intrinsic evidence would have to “clearly disavow” the ordinary meaning. As the dissent put it, the majority categorized intrinsic evidence as an “also-ran” in claim construction.
