Study of Global LED R&D

Analyses of LED & SSL patenting have focusedprimarily on US data

To probe international R&D, need more globalmeasure

Counts based on one nations patents havehome-nation bias Multi-national patent & applications data

Opportunity to probe corporate & national R&Dactivity in novel ways

Unique comparison of inter-country, inter-firmtrends World patents, not just US

Data Overview European Patent Offices Worldwide

Patent Statistical database 185,852 applications filed in 68 nations

Filed mid-1930s to Dec. 4, 2008

Granted up to March 5, 2009 (in that case,applied for April 12, 2002 in Germany) 59,633 granted patents 12,499 granted utility models and (in a few

cases) other receipts such ascommunist-style inventors certificates

Search Methods

Recursive search to identify LED-relatedpatents & applications Based on classification codes (IPCs), title

keywords

Inventor & applicant nationalities often not inavailable data Random sample of missing data used to

determine frequencies of nationalities Multi-lingual research team looked up original

documents to determine countries Also to check whether China locations were inmainland China vs. Taiwan

Observations

Greater role of international companies than seen in US datan Samsung zooming to top of patent rankings, most prominent in

displays & OLEDsn SSL activity global, growing Asian role

n Taiwan and mainland China many individuals & smallcompanies

n Manufacturing locus in Chinan Traditional lighting firms transitioned into SSL through joint

ventures & acquisitionsn Major competition from strong consumer electronics firmsn For small firms--where are major opportunities?

Challenge of Competing inEmerging Markets

US firms lost initial leadership in flat panel displayindustry including liquid crystal display (LCD),light emitting diode (LED) display and plasmadisplay panel (PDP)

Failed to invest in scaling-up during crucialtechnology development phase beginning withthe LCDs

Is there a similar pattern in other emergingindustries?

What can be done to ensure the mistakes in LCDsdo not recur in other emerging industries? Do stayers develop a competitive advantage?
