sale  by  the  defendant  of  machines  embodying  the  patented  inven-
tion, upon  which  some  money  was  recovered,  and  real  estate  was

that  this  was,  prima  facie,  a  satisfaction  of  the  decree  ;  and  that

his  patent  by  the  use  of  machines  purchased  from  the  defendant  in
the  former  suit,  and  for  the  manufacture  and  sale,  for  use  of  which

267.    Operation  and  Effect  of  Injunctions  in  Patent  Cases.
Purchasers  from  an  infringer  who  has  been  enjoined  by  a  cir-
cuit court,  cannot  be  permitted  to  use  the  machine  purchased  in
another  circuit  while  the  injunction  remains  in  full  force.  Wood-
worth  V.  Edwards,  3  Wooclb.  S  M.  120.
An  injunction  in  a  patent  case  does  not  extend  beyond  the  right
of  the  plaintiff,  as  set  up  in  his  bill.  Byam  v.  Eddy,  2  Blatchf.

To  sell  parts  of  a  patented  device  necessary  to  its  operation  but
not  covered  by  the  patent,  does  not  constitute  a  new  infringement,
when  they  have  already  been  charged  in  the  accountings  for  the
sale  of  the  patented  portion.  Buerk  v.  Imhauser,  II  Pat.  Off.  Gaz,
112.
