I believe the key words are future license agreements may result in a differant method of revenue recognition. Because all company's have chosen one lump sum payments so far the method of revenue recognition they outlined works. However as we learned from PTSC, TPL is offering a royalty payment type plan as an option for company's but none have chosen this payment option yet. When and if a company chooses the royalty payment option then a differant method of revenue recognition will be required. At least that is how I interperate the first sentence you highlighted.

The maintenance and support fees sentence I really don't understand. This may be a way to collect from the J's over time but I just don't know.

All the best,
