Markman Decision from Judge Farnan

Judge Farnan recently construed the terms below for claims related to technology used to "optimize the rate at which data can be transmitted across communication channels." CIF Licensing, LLC v. Agere Systems, Inc., C.A. No. 07-170-JJF, Memo. Op. (D. Del. July 10, 2008):

-"receiver"
-"line probing processor"
-"selector"
-"for selecting one of the plurality of frequency bands"
-"for selecting one of the plurality of bit rates"
-"constellation"
-"constellation switching"
-"can be"
-"frame selector"
-"zero insertion unit"
-"signal constellation selector/mapper"
-"operably coupled"

Judge Farnan further found that the preambles of certain claims were limiting under the recent Federal Circuit decision Symantec Corp. v. Computer Assocs. Int'l Inc., 522 F.3d 1279 (Fed. Cir. 2008).
