Justice Floyd has today given two judgments in the case of Samsung Electronics Co Limited v Apple Retail UK Limited and others, concerning three patents owned by Samsung which were alleged to be infringed by Apple's 3G devices including models of iPhone and iPad.

Mr Justice Floyd found all three Samsung patents to be invalid on the basis that they were not entitled to the priority dates claimed. The decisions concern the following patents:

1. EP1005726

"Turbo encoding/decoding device and method for processing frame data according to QOS"

2. EP1357675

"Apparatus and method for channel coding and multiplexing in a CDMA communication system"

3. EP1714404

"Apparatus and method for allocating OVSF codes and I/Q channels for reducing peak-to-average power ratio in transmitting data via enhanced up-link dedicated channels in WCDMA systems"

The judge further found that '726 and '404 would have been obvious in any event even if they had been entitled to their priority dates. As regards '675, the judge decided that if it had been entitled to priority, it would have been valid as proposed to be amended.  '726 and '404 would have been infringed by Apple devices had they not been found invalid.
