ORDER REQUESTING

SUPPLEMENTAL BRIEFING

On March 9, 2006, the Court held a hearing for the purpose of construing key disputed

terms in the claims of United States Patents No. 4,698,672 (“the ‘672 patent”). The Court

concludes that it needs additional information from the parties in order to construe the term:

“digital signals” and “processed signals.” The parties agree that both terms should be given the

same construction, as Defendants note: “The parties agree that the Court should construe the

terms ‘processed signals’ and ‘digital signals’ identically for the purposes of the claims at issue. 

Unless otherwise noted, Defendants use the term ‘processed signals’ to refer to both ‘processed

signals’ and ‘digital signals.’” Defendants and Declaratory Judgment Plaintiffs’ Responsive

ORDER REQUESTING SUPPLEMENTAL BRIEFING

(JFLC1)

Markman Brief, p. 7 n.3. 

The Court is inclined to construe the term “processed signals” as limited to video signals,

based upon the way this term is defined in the specification of the patent: “The processed signals

are in the form of a plurality of multivalued digital numbers, X(k), typically one number X(k),

for each frame.” ‘672 Patent col.3 ll.54-56 (emphasis added); see also ‘672 Patent col.12 ll.38-

43 (providing the meaning of “X(k)”). However, because the Court believes that “processed

signals” are a subset of “digital signals,” the Court hesitates to give this specific construction also

to “digital signals.” The fact that the parties agree that the terms should be given the same

construction does not by itself persuade the Court that it also should limit “digital signals” to

mean only those digital signals that represent frames of a video. The Court has found no

evidence in the ‘672 Patent to justify importing a limitation that appears to apply only to

“processed signals” to “digital signals.” Accordingly, the Court hereby requests supplemental

briefing, which shall address only the question of whether “digital signals” and “processed

signals” should be given the same construction and, if so, why. The briefing shall not include

argument with respect to the question of whether the term “processed signals” should or should

not be limited to video signals. CLI’s brief shall be filed on or before May 19, 2006, and

Defendants’ brief shall be filed on or before May 26, 2006. Each brief shall not exceed five

pages in length. 

IT IS SO ORDERED.

DATED: May 12, 2006
