Judge Rodney Gilstrap in the Eastern District was assigned 941 cases, more than double his nearest colleague. The top 10 plaintiffs were so-called patent monetization entities — popularly known as “patent trolls” The most active troll was Melvino Technologies/ArrivalStar with 137 cases. Apple AAPL was the defendant in the most new cases — 59 in all, not counting summary judgements. Monsanto won the largest award ($1 billion) from Dupont. Apple was No. 2, winning $890 million (excluding costs, fees and post-judgment interest) from Samsung. Below: The top 10 defendants.
