Pace of patent litigation declines; 2018 applications still flat

Early indications are that U.S. patent litigation for 2018 is on track to be among the lowest in since 2005.

So far in 2018, approximately 555 patent infringement suits have been filed (3,330 on an annualized basis). This is off from a peak of 5,874 in 2015, or an average of 979 every two months. In 2005, the lowest litigation filing year in recent memory, there were just 2,582 suits. In 2017, there were 4,072. January and February are early indications, and there is time for the rate to increase.

According to statistics provided by intellectual property research firm Patexia, January 2018 patent applications came in at 27,720, just 631 higher than 2017, 27,089, which was the lowest year for that month since 2012. February applications are running behind last year, which came in at 28,329 for the same month. Final figures are not yet in.

This trend in patent applications and litigation has been accompanied by a flattening of Inter Partes Review (IPR) petitions filed. IPRs have been fairly level for the past three years, peaking in 2017 at 1,725. So far this year (through February) there have been approximately 250 IPRs filed, putting 2018 on track for about 1,500, slightly below the last two years on an annualized basis. No information on the number or percentage of instituted petitions was provided.

Litigation, IPRs and CBMs Filed to Date

IPRs and Litigation

Difficulty obtaining software and business methods patents are a likely reason for the drop in U.S. patent applications, as well as the increased difficulty defending patents. Patent uncertainty and decreased need for defendants to take a license or engage in licensing discussions, as well as the high cost of litigation, are possible reasons for an increase in IPRs.
