Casio and HP must have been compelled enough by this program to get on early. Why not others? Rhetorical.

Licensing - MMP Portfolio Licensing Program
It has been widely acknowledged that the MMP Portfolio contains several fundamental building blocks of modern microprocessor architecture and implementation. As a testament to this reality, marquee chip makers Intel and AMD were early to purchase MMP Portfolio licenses to cover their microprocessor designs.
In light of these early, important licensing endorsements by Intel and AMD, the market demanded greater clarity and certainty. Since modern systems contain many microprocessors, system manufacturers would remain exposed until all their parts vendors obtained licenses. Indeed, system manufacturers would be exposed not only to infringement claims but also to supply chain and product design disruptions.
The MMP Portfolio Licensing Program therefore focuses licensing requirements and royalty collection on the finished ``system-level`` product. A royalty-free MMP Portfolio license is also available to manufacturers of chips and other unfinished goods.
Unconstrained by associations with formal standards setting processes, the MMP Portfolio Licensing Program rewards first movers in their industry sectors with dramatic discounts. By design, this structure enables nimble and forward-thinking companies to disadvantage their competitors. Such a company is Hewlett-Packard, which became the first system manufacturer to purchase an MMP Portfolio System License.
