This report provides a detailed picture of the patent landscape for LED phosphors and other down-converters like quantum dots.
• Understand who owns what.
• Identify key patents by composition or assignees.
• Understand trends in phosphor composition IP.
• Identify the major players in LED phosphor IP and the relative strength of their portfolio.
• Identify collaboration networks between key players (industrial and academics).
• Emerging IP from China.
• Overview of past and current litigations, licensing agreements.
• Overview of essential market data and forecast for LED Phosphors.

The report identifies the key players with the most relevant IP. It provides an overview, of phosphor related IP litigation and licensing, that has shaped the industry since the mid 90s, as well as a detailed analysis for the major players involved.

Our search strategy combines automated and manual screenings that have led to the selection of more than 4,500 relevant patent families. Those have been segmented by type (composition patent or phosphor configuration patents) and organized in various technology segments that are analyzed in detail: garnets, silicates, nitrides and oxynitrides, quantum dots. The report also includes a special focus on the emerging LED phosphor IP in China. For each segment, the report provides a detailed analysis including the time evolution of patent filings, identification of the key players, collaborations and citation networks, as well as the identification of the key patents based-on citation and impacts in litigations.
The report also includes a companion excel database with all patents of the company profiled in the report. This database includes abstracts and hyperlinks to the original documents and allows multi-criteria searches (patent publication number, priority date, title, applicants, technological segments…).

Hundreds of companies are involved in LED phosphor IP. Most of the major LED players are present in the list of the top patent assignees. But independent phosphor manufacturers like Intematix or Mitsubishi that are offering their phosphors on the open market are also emerging as major forces in the IP landscape. Leading Taiwan based packagers are notably absent from this ranking. This weak position explains the large number of litigations and one way, royalty or supply based license agreements involving those companies.

The report provides an analysis and ranking of the relative strength of the top Led phosphor IP holders derived from their portfolio size, patent citations networks, number of family etc…
Based on this portfolio analysis as well as on their litigation and licensing history, we have identified 15 major players that are profiled in this report. Each profile includes a detailed portfolio analysis with the time evolution of patent filing by segment as well as a list of key patents, citations, collaborations, litigations and licensing.
