I've written below that I believe the Federal Circuit really messed up the interpretation of Section 285 in Brooks Furniture and other cases. In updating my book, I remembered another aspect: courts also sometimes follow dicta in Brooks Furniture that an assertion of infringement is presumed in good faith. Brooks Furn., 393 F.3d at 1382. E.g., MTS Sys. Corp. v. Hysitron Inc., 639 F. Supp.2d 996 (D. Minn. 2009).
If you read the cases cited by Brooks Furniture, they don't have anything to do with presuming infringement claims are made in good faith; the cases hold, only, that belief in validity is presumed in good faith (because of the presumption of validity). This has raised the bar too high.
On a much more interesting note, the Chiefs are giving the Broncos a good game! (I am a Cowboys fan, lifetime. No flames allowed!).
