I follow Florian Mueller (@FOSSPatents) for his take on most of the Qualcomm v Apple litigation (including the recent FTC antitrust case). He seems to be somewhat anti-Qualcomm (although that might just be based on his perception of their likelihood of winning). His take: [0]
> ITC judge disagrees with ITC staff, sides with Qualcomm against Apple: one patent held infringed, import ban recommended; but patent likely invalid
> Administrative Law Judge (ALJ) MaryJoan McNamara just announced an initial determination ("initial" means the parties can seek a Commission review, and a final ruling is still four months off) according to which Apple is deemed to infringe one of three Qualcomm patents-in-suit... In my observation, decisions by ITC judges that run counter to staff recommendations are virtually certain to be reviewed and more likely than others to be reversed.
Also, the patent is for "multiple supply-voltage power-up/down detectors" and is currently being reviewed by the USPTO for validity.
