Ray Lupo and Paul Devinsky were quoted in the National Law Journal on February 9 on the Federal Circuit's shifting views on how to define the words or claims that describe the scope of a patent. In Texas Digital Systems it ruled that dictionary definitions are the first source for construing the meaning of a claim. "The court backed off on Texas Digital," commented Mr. Lupo. It has tried to harmonize Texas digital with a 1996 decision (Vitronics) where it established tools courts should use to evaluate claim constructions. In the Vitronics decision specifications in the patent were considered the most important tool. "In Judge Richard Linn's view, you go to the dictionary first, and only if the specification is inconsistent with the dictionary need it be considered," commented Mr. Devinsky. "In Judge Michel's view, the specification has to be consulted in every claim construction."
