Defendants' motion for summary judgment of indefiniteness of two of plaintiffs' patents-in-suit was granted. "[W]e agree with [defendants] that 'at least about' does not sufficiently inform the public on what would infringe. . . . There is simply no intrinsic evidence that the word 'about' coupled with 'at least' has an accepted meaning."
