March again saw a very slight increase as the NPEs continued waiting on Oil States.  Frequent filers included Aeritas, Electronic Receipts Delivery Systems, Grecia, Finjan, Hawk Technology, Hybrid Audio, Internet Media Interactive, Landmark Technology, Lit, Location Based Services, Tangelo IP, and Uniloc.

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 or 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 your suggestions for improving the report.
