Opinion of SCALIA, J. 

SUPREME COURT OF THE UNITED STATES

ASSOCIATION FOR MOLECULAR PATHOLOGY,

GENETICS, INC., ET AL. 

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 

APPEALS FOR THE FEDERAL CIRCUIT
 

[June 13, 2013] 

JUSTICE  SCALIA,  concurring  in  part  and  concurring  in 

the judgment. 

I  join  the  judgment  of  the  Court,  and  all  of  its  opinion 
except Part I–A and some portions of the rest of the opin-
ion  going  into  fine  details  of  molecular  biology.    I  am  un-
able to affirm those details on my own knowledge or even 
my own belief.  It suffices for me to affirm, having studied 
the  opinions  below  and  the  expert  briefs  presented  here, 
that  the  portion  of  DNA  isolated  from  its  natural  state 
sought  to  be  patented  is  identical  to  that  portion  of  the 
DNA  in  its  natural  state;  and  that  complementary  DNA 
(cDNA)  is  a  synthetic  creation  not  normally  present  in 
nature.
