Patent data can help uncover the trends, gaps and opportunities that exist around use of LEDs in lighting industry. By observing trends in patent filings by innovators and businesses it’s possible to take a closer look into LED lighting and gauge where it’s headed. Some of the questions around this technology we are now starting to see more often in our daily lives are:
• How research activity around LED lighting technology evolved since 1920 and which companies spearhead the research?
• Who are the innovators whose filings dominate LED lighting technology?
• Which countries are showing the maximum activity in LED lighting research?
• How does LED lighting compare with other forms viz. Incandescent and Fluorescent lighting?
• How the filings are spread across key LED Lighting products in the market?
To get some answers and a better insight into the IP activity that surrounds it, we carried out a quick analysis using Patent iNSIGHT
IP Activity across Last 60 Years
What has been the IP publication trend for LED light technologies from 1950 till present date?
Patents related to LED technology can be traced back to before 1950 and the real surge in the activity around this technology has happened
in the last decade. Patent publication trends are accurate indicators of the emphasis given to a technology during a particular point of time and by laying out the patent activity across a timeline of the last 6 decades, a landscape of how this activity has evolved is created: While there were some significant number of patents published from the 50’s to the 80’s, there seems to be a complete dip in the activity around LED technology for a significant period of time till the last decade where the filings started to climb rapidly. From just 22 filings in 1990, the year 2000 saw the number jump to 80 and shoot up to 1700 in 2009 indicating this technology has gone from ‘dormant’ to ‘very hot’ in the very recent years. The first few months of 2010 already show this upward trend and development around LED lighting is only poised to go upward at the same sharp rate it’s currently growing at. LED is clearly getting a lot of attention and investment in current times and comes across as a promising technology in the future of lighting systems.
Key Companies in LED Lighting Technology
Who have been the top assignees or the key players in LED lighting technology?
With the rise in research and development activity around LED related lighting technologies in the last decades, large businesses have established their interest through significant investments. By grouping the patent filings by companies, we can establish who the top assignees or key players in LED lighting are:
With companies like Phillips, Samsung and Koito leading the table with the most patents a number of the leading companies in the general lighting systems space appear to be pursuing LED technology with enthusiasm as a future technology which has strong potential in commercial markets
