Abstract: This paper utilizes an extensive dataset of 163,663 US patents granted between
1976 and 2011 to 25 companies within four technological fields (aerospace industry,
computer manufacturing, semiconductor industry, and software development),
to observe fluctuations in their value and characteristics. I find that
certain indicators have changed immensely during the last 36 years, suggesting
that newer patents are much less valuable than their predecessors. Further,
using Data Envelopment Analysis, I estimate relative production efficiency of
transformation of inputs (research and development expenses and company’s
workforce) into outputs (patent stock and its technological importance), to
provide an empirical evidence for the recent theories of strategical patent exploitation
by large companies. I find that the efficiency varies considerably for
different industries and also for the companies within an industry. There is an
overall trend of increasing efficiency in patent production per unit of input, but
there is none in the effectiveness of creating valuable inventions, which seems
to depend only on the company itself.
