The report identifies the key players, provides an overview of phosphor-related IP litigation and licensing, with detailed analysis. Here’s an overview:

According to the researcher, more than 20,000 patents have been identified and 4,500 relevant patents have been selected for analysis. These are segmented by type in the report and organized into such materials segments as:
  • Garnets
  • Silicates
  • Nitrides

The report also places special emphasis on the emerging LED phosphor IP in China. One point of interest is that Taiwan-based packagers are notably absent which also accounts for some of the litigation activities.
