USA Patent litigation is once again on the rise after what now appears to be an only temporary dip in 2014. There were 1,443 patent filings in the first quarter this year, according to an analysis by Unified Patents, which hand sorts out duplicate filings. Unified is an advocacy organization with the stated goal of deterring frivolous patent litigation.
If present trends continue, there would be an estimated 5772 filings
for calendar 2015, a 15% increase over the previous year, when Unified
reported there were 5,002 suits.
Patent litigation filings have been up and down in recent years, with
a record high of more than 6,000 filings in 2013. In 2014, however,
patent litigation declined slightly for a variety of reasons.
