Ahead of Apple and Samsung’s California patent trial, the two companies recently filed final narrowed lists of patents and products both sides are accusing the other of infringing. As part of the slow march toward the second Apple vs. Samsung patent trial to take place in the US District Court for the Northern District of California, both parties entered proposed their narrowed patent claims to presiding Judge Lucy Koh.

Apple and Samsung were ordered to limit their respective cases to manageable size, which Judge Koh first defined at 25 patent claims and 25 products in early 2013. As noted by Florian Mueller of FOSS Patents, the parties went through a few rounds of case narrowing since then and have successfully whittled he number of patents and accused products down to five and ten, respectively.

Samsung is actually asserting five claims from four patents after having its case pared down in January when Judge Koh invalidated an entire patent in a pre-trial summary judgment. The Korean company chose to assert a second claim from one of its four patents-in-suit. Samsung's asserted patents and infringing products included the following:

Patents
  • U.S. Patent No. 7,756,087 for a "Method and apparatus for performing non-scheduled transmission in a mobile communication system for supporting an enhanced uplink data channel" - Claim 10
  • U.S. Patent No. 7,551,596 for a "Method and apparatus for signaling control information of uplink packet data service in mobile communication system" - Claim 13
  • U.S. Patent No. 6,226,449 for an "Apparatus for recording and reproducing digital image and speech" - Claim 27
  • U.S. Patent No. 5,579,239 for a "Remote video transmission system" - Claims 1 and 15

  • iPhone 5
  • iPad 2

On the other hand, Apple escaped the pre-trial phase with all five claims from five different patents intact despite attempts by Samsung to invalidate a control signals property on the grounds of prior art. Apple’s asserted patents and infringing products are as follows:

Patents
  • U.S. Patent No. 5,946,647 for a "System and method for performing an action on a structure in computer-generated data" - Claim 9
  • U.S. Patent No. 6,847,959 for a "Universal interface for retrieval of information in a computer system" - Claim 25
  • U.S. Patent No. 7,761,414 for "Asynchronous data synchronization amongst devices" - Claim 20
  • U.S. Patent No. 8,046,721 for "Unlocking a device by performing gestures on an unlock image" - Claim 8
  • U.S. Patent No. 8,074,172 for a "Method, system, and graphical user interface for providing word recommendation" - Claim 18

Mueller pointed out that neither company’s current-generation products are being accused of infringement, a fact that shines a light on the speed of existing US patent litigation procedures. Instead, devices accused are from 2012 or later, many of which no longer sold or even manufactured. The products, however, can serve as a basis for damages and injunctive relief, while any trial decisions can have implications on future hearings. Last but not least, Samsung also filed a status update on an ongoing effort to invalidate Apple’s ‘172 patent-in-suit. An ex parte, or anonymous petition to have the property re-examined has seen progress with the US Patent and Trademark Office now agreeing to take a closer look at certain aspects of the patent.

The second Apple vs. Samsung court battle is set to begin on March 31.
