According to a DAC panel, most designers think of a block of IP as a product when the IP should really be thought of as a service. The reason is because there is often a need for continuing support from the IP supplier. IP licenses rarely come with a guarantee. On the other hand, products usually come with some type of guarantee regarding their functionality.
In some cases, IP vendors are starting to build walls, protecting themselves from potential legal actions. The companies are becoming lawyer driven. If IP is classified as a product, legal protections and liabilities could require an army of lawyers. However, if viewed as a service, IP vendors, working closely with customers, could put many of the lawyers out of the picture and simplify the working relationship.
