Academic Patenting Revolution

IP-oriented emerging technologies ; Biotech, Nanotech,…

Patent-oriented laws USA/European countries: Dayh-Dole Act like

legislations

More active role that academia has been asked to play in the Knowledge Economy

Page 7: From science to license:  an exploratory analysis of the value of academic patents

Pending questions

Management of Technology transfer Spin-offs; licenses; research contracts/ alliances

etc…

Debates related to the roles of university

Dissemination of science The balance between the different missions of

universities Quality of research; quality of patents

Patent Value

Page 9: From science to license:  an exploratory analysis of the value of academic patents

State of the art (1) The distribution of patents’ value is highly

skewed

Value Proxies Monetary value of a patent (e.g. Harhoff et al., 1999, 2002) Present value evaluated by experts (e.g. Reitzig, 2003) Forward citations (e.g. Lerner, 1994; Sapsalis and van Pottelsberghe,

2006, 2007) Composite indicator (e.g. Lanjouw and Schankerman, 1999) Creation of a start-up (e.g. Shane, 2001) Probability to get a patent …

Granted (e.g. Guellec and van Pottelsberghe, 2000) Opposed (e.g. Lanjouw and Schankerman, 1997) Renewed (e.g. Lanjouw and Schankerman, 1999) Licensed (e.g. Dechenaux et al., 2003 )

State of the art (2) Value determinants

Forward citations ++++ (ex: Shane, 2001) Patent family size ++ (ex: Lanjouw and Schankerman,

1999) Results of opposition & annulment procedures : + (ex: Harhoff et al, 2003) Backward patent citations: + (ex: Harhoff and Reitzig, 2000) Non-patent citations: (+) (ex: Harhoff and Reitzig, 2000) Claims: (+) (ex: Lanjouw and Schankerman,

1997) Patent scope: (+/-) (ex: Lerner, 1994) Time: + (ex: Guellec and van

Pottelsberghe, 2002) Technical field: (*) (ex: Harhoff et al, 1999) Ownership characteristics: (*) (ex: Guellec and van

Pottelsberghe, 2002)

standing for a license given to industry

Entrepreneurial impact: dummy variable standing for a licence given to a spin-off

Setting hypotheses (1)

FPC-Co) Startup License = f+(FPC-PRI ; FPC-Co)

Scientific base # forward patent citations = f+(NPC-self); f -

(NPC-non self) Industry License = f+(NPC-self); f -(NPC-non

self) Startup License = f+(NPC-self); f -(NPC-non

Concluding remarks (1)

Policy implications Focus on high level scientists

importance of tacit knowledge

Importance of collaboration Academic collaboration: + tech impact ; -

ind impact Industrial collaboration: + ind impact

importance of close contact with industry

Page 28: From science to license:  an exploratory analysis of the value of academic patents

Concluding remarks (2) Management implications

TTO and Funding bodies Management of IP co-developed by different

public research institutions Spin-offs and established companies exploit

different types of patents

Further research Analyse commercial impact Analyse the impact of academic inventions

on industrial portfolio
