More information about the iPhone trademark lawsuit has been coming out.

First, it appears that Cisco and Apple's negotiations had continued until 8pm the night before the keynote address. Cisco had wanted Apple to ensure interoperability between Cisco's Voice over IP Internet Phone (iPhone) and Apple's new iPhone mobile phone. Apple reportedly rejected this offer.

Meanwhile, one trademark attorney claims that Cisco may have lost rights to the iPhone trademark last year by failing to provide convincing evidence of ongoing use of the iPhone trademark by the proper deadline.

If Apple can prove in federal court that the Declaration of Use contained misstatements of fact, i.e. that there was no continuous use, then Cisco's registration can be canceled.

Meanwhile, readers note that Apple has been careful to place the Apple logo in front of all references to the iPhone on their web pages.
