Separately from the case that's attracted so much media attention, Apple started legal action against Samsung in February, claiming that 17 of the company's smartphones and tablets - including the Galaxy S II and the Galaxy Nexus - infringed its patents.
Apple has now added another four devices to the list: two versions of the Galaxy S III, the Galaxy Note, and the Galaxy Note 10.1.
The allegation is that these 21 devices infringe eight patents held by Apple.
Unlike what's now being referred to as "the earlier case," none of the eight are design patents (which are known as registered designs in some jurisdictions).
Rather, they are all technological patents.
The list includes patent 5,946,647 "System and method for performing an action on a structure in computer-generated data," and 8,046,721 "Unlocking a device by performing gestures on an unlock image".
The company is asking for a judgement that the patents are valid and enforceable, that Samsung has infringed them, an injunction against further infringement, damages "in no event less than a reasonable royalty", treble damages for infringements found to be wilful, actual damages suffered by Apple as a result of the infringement, costs, and an award of all of Samsung's profits.
Apple is demanding a jury trial, and the case is expected to be heard in March 2014, by which time Samsung is likely to be selling a whole new range of devices.
