the standards for establishing patent damages awards by rejecting the commonly used 25 Percent Rule in calculating a reasonable

The 25 Percent Rule is a general "rule of thumb" that says a patent infringer should pay 25 percent of the expected profits
for the product that incorporates the patent at issue.

One of the greatest obstacles in passing legislative patent damages reform is the diverging interests of the pharmaceutical
and biotechnology industries versus the high technology industry. The high technology industry, which develops complex products
that include an array of technologies covered by a significantly large number of patents, has been strongly advocating for
a limit to the amount of damages awarded in patent infringement cases. On the other hand, the pharmaceutical and biotechnology
industries need strong, appropriately valued patents, as their products, which are covered by fewer patents, require substantial
time and investment costs when being brought to the market.

Prior to the Uniloc decision, Congress' last attempt to reform patent damages was a Senate proposal in the 111th Congress (2009 to 2011) that
involved a compromise approach between the stakeholders whereby the district court judges would serve as a "gatekeeper" in
handling damages so as to exclude unsound theories and irrelevant evidence, and provide clear jury instructions. Shortly after
the Uniloc decision, patent damages reform legislation was reintroduced in the Senate during the current 112th Congress (as part of
S.23: Patent Reform Act of 2011) and contains the same gatekeeper provisions as earlier proposed.
Some judges of the Federal Circuit, which is a specialized court that has exclusive jurisdiction for all patent appeals, have
been vocal about their opposition to patent damages reform, believing instead that the courts can handle the issue without
The inability of Congress to pass legislative reform addressing patent infringement damages has provided courts the opportunity
to address the issue in a series of decisions that have tightened the standards for calculating reasonable royalty rate damages
in patent infringement cases. The Uniloc decision is the most recent in this series.
