OLED materials patents grew 200% in 2 years

August 25, 2011 — Cintelliq’s "OLED lighting: A review of the patent landscape" report shows the fastest growth in organic light emitting diode (OLED) patents 2008-2010 came from the materials sector. During the 2-year period, the total number of OLED patents published grew by 56% from 1,767 to 2,760, with no signs of slowing. The largest group of OLED patents (>260) went to traditional lighting companies.

Patent filings by academic and research institutes grew by nearly 200%. During the same period, device patents growth was the highest in terms of absolute numbers, but the highest growth rate was in terms of patents for ‘ancillary’ aspects of OLED panels: drimmer units, power units, mountings and fixtures. Applications patents, materials, fabrication and outcoupling all grew by more than 50%.

Increasingly, patents refer to LED and OLED as the solid-state light source, suggesting that — from an applications persepctive — the two technologies are interchagable.

"OLED lighting: A review of the patent landscape" identifies more than 2,760 patents focused on white OLED technology for lighting applications, notes Craig Cruickshank, lead analyst, cintelliq Limited. Cruickshank expects OLED patent filings to continue to increase as "companies seek to secure exclusive technology domains." The research for this report is based on more than 2,700 patents - 310 granted patents (EP and US) and 2,450 published (EP, JP, US and WO), that have been made public up to December 2010.
