As recently as 1978, intangible assets, such as intellectual property, 
accounted for 20 percent of corporate assets with the vast majority of 
value (80 percent) attributed to tangible assets such as facilities and 
equipment.  By 1997, the trend reversed; 73 percent of corporate assets 
were intangible and only 27 percent were tangible.

today’s decision, statute and precedent have provided stability in the rapidly moving and 
commercially vibrant fields of the Information Age.  Despite the economic importance of 
these interests, the consequences of our decision have not been considered.  I don’t 
know how much human creativity and commercial activity will be devalued by today’s 
change in law; but neither do my colleagues. 
The Section 101 interpretation that is now uprooted has the authority of years of
