  4. IMPORTF - IMPORTB Time • Citied Patents • Second Generation 7 3 6 (g-1) Backward • Citied Patent • First Generation (-g) P1 P2 P3 Patent(i) • Measured Patent • Citing Patents • First Generation P1 P2 P3 P4 P5 P6 (+g) Forward • Citing Patents • Second Generation 8 5 5 3 3 5 (g+1) 2011 Jaffe & Trajtenberg (2002).

  5. Citing i IMPORTF(i)=NCITING (i) + λNCITING i+1j Σ j =1 Cited i Σ IMPORTB (i)= NCITED (i) + λNCITED i+1j j =1 λ= 0.5 IMPORTF – IMPORTB Results • They have described different λ's in the different equations: • "different λ'sλ= 0.25 λ= 0.5 and λ= 0.75 but none of the results appear to "depend upon". (Jaffe & Trajtenberg, 2002: 60). Jaffe & Trajtenberg (2002). Patents, citations, and innovations : A window on the knowledge economy. Cambridge, Mass., MIT Press.

  6. Time • Citied Patents • First Generation P1 P2 Patent(x) Patent(y) • Measured Patent Cited P1 P2 Citing • Citing Patents • First Generation 10 10 10 10 2011 • Second Generation • Second Generation What is the problem? IMPORTF (xy)= 6.0 Citing i Σ IMPORTF (i)= NCITING(i)+ λNCITING i+1j j =1

  7. The presumptions Patent importance values are based on patent citation data by counting backward and forward first and second generation patent counts. Citing patents are more important than cited patents. Forward second-generation patents (citing) are more important than backward second - generation patents. Backward citation information is the ground stage from which we can proceed with further research.

  8. Second Generation Discrimination Time • Citied Patents • Second Generation 4 3 1 3 4 2 7 3 6 (g-1) • Citied Patent • First Generation Backward P1 P2 P3 (-g) Patent(i) • Measured Patent • Citing Patents • First Generation P1 P2 P3 P4 P5 P6 (+g) 8 5 5 3 3 5 Forward • Citing Patents • Second Generation 4 4 3 2 0 5 2 1 0 3 3 2 (g+1) 2011 Jaffe & Trajtenberg (2002).

  9. Empirical dynamic λ factor Patent(i) Time • Measured Patent P1 • Citing Patents • Second Generation • Citied Patents • Second Generation 8 bc (g+1)(P1) fc (g+1)(P1) 2010 Time ) ( fc (g+1)(P1) λ Df(P1) = fc (g+1)(P1) (1+ (fc (g+1)(P1) + (bc (g+1)(P1)) λ Df(P1) =λDynamic forward Second Generation fc(g+1)(P1) = Forward Second Generation (citing) bc(g+1) (P1) =Backward Second Generation (Cited)

  10. Empirical dynamic λ factor ( fc (g-1)(P1) ) λ Db(P1) = fc (g-1)(P1) (1+ (fc (g-1)(P1) + (bc (g-1)(P1)) λ Db(P1) =λDynamic backward Second Generation fc(g-1)(P1) = Forward Second Generation (citing) bc(g-1) (P1) =Backward Second Generation (Cited)

  11. Modified Forward Importance N(g) N(g+1) ² Σ Σ (fc (g+1)) FI(i) = ( ) FC + (1+ (fc (g+1) + (bc (g+1) P=1 P=1 FI(i)= Forward Importance FC (g)= First Generation (citing) fc (g+1)= Forward Second Generation (citing) bc(g+1) =Backward Second Generation (Cited) Citing i Σ IMPORTF(i)=NCITING (i) + λNCITING i+1j j =1

  12. Modified Backward Importance N(-g) N(g-1) ² Σ Σ ( (fc (g-1)) ) BI(i) = BC + (1+ (fc (g-1) + (bc (g-1) P=1 P=1 BI(i) = Backward importance BC (g)= First Generation (cited) fc (g-1)= Forward Second Generation (citing) bc(g-1) =Backward Second Generation (Cited)

  13. PatentImportance • The presumptions The discrimination of second - generation patents The dynamic - λ factor. Modification of Forward Importance Patent Modification of Backward Importance Patent Importance Patent Factor – (IPF)

  14. Patent Importance Factor Mechanical Advantage = (Output Force) : (Input Force) Gain (db) = Power Output : Power Input Backward citation information is the ground stage from which we can proceed with further research. IPF (i) = Fi(i) : BI(i):

  15. Importance Patent Factor ² N(g) N(g+1) ( (fc (g+1)) ) Σ Σ FC + (1+ (fc (g+1) + (bc (g+1) P=1 P=1 IPF (i) = N(-g) N(g-1) ² ) ( Σ Σ (fc (g-1)) BC + (1+ (fc (g-1) + (bc (g-1) P=1 P=1

  16. Future Research • There is a need for more Patent Impact Factor Indicators (PIFI). “Time Scale Factor“ “Class Analysis Factor “ Others …….
