Electronics & Computer
Electronics are essential to providing power electrically, to communication and media technologies, and to measuring and monitoring systems. Consequently, microprocessors and computers have since become highly differentiated in terms of their functions, with no end in sight. A successful business model can be based on selling a product (electronics, processor, computer) and licensing a patent portfolio protecting the product. The successful SoC (system on a chip) licensing model in wireless devices is just one example of this.
Independently protecting all new functions of a computer or electronics assembly wherever possible can build a strong patent portfolio unable to be circumvented as a whole. As of that point, business models based on licensing revenue can be developed.
