December was only surprising for not showing a holiday-related drop off in retail-related patent filings.  The continued stength of troll filings may be an indicator of a strengthening economy, or it may be a continued surplus of cases because trolls paused after enactment of the America Invents Act to understand its impact upon their cases.

As usual, I prepared the report in partnership with and using Docket Navigator and its powerful database.  Docket Navigator is a valuable resource, and the place to go if you want to keep track of new patent litigation filings or want to know what is happening in particular cases, how your judge has historically handled a particular type of motion, or a particular plaintiff’s litigation history.

Finally, please let me know if you have thoughts about the report and changes you would like to see.  I am preparing it as a service for retailers and their supply chain who may want an overview of the patent litigation landscape.  So, I am very open to ways to improve the report for you.
