Europe Revokes HFO-1234yf Patent

A tribunal of the European Patent Office (EPO) heard oral arguments in March of this year after formal objections to Honeywell’s HFO-1234YF patent were filed by Daikin Industries, Daimler AGE, ACEA, BMW AG, Mexichem, Solvay Fluor and others in November of 2009.  The tribunal’s decision is as follows-
“The patent is revoked under Article 101(2) EPC as at least one of the grounds of oppositions prejudices its maintenance unamended, and under Article 101(3) (b) EPC because taking into account the amendments made by the proprietor during the opposition proceedings, the patent and the invention to which it relates do no meet the requirements of the EPC.”
(European Patent Convention)
Honeywell has filed a Notice of Appeal.

EPA Petitioned to Withdraw Approval of R-134a

The  Environmental  Investigation  Agency  (EIA)  filed  a  petition  requesting that  the  EPA  phase-­out  the  use  of  R134a  in  most  applications  in  the  U.S. According  to  the  EIA,  “HFC-­134a  has  a  global  warming  potential  (GWP)  of 1430  (making  it  1430  times  more  powerful  than  CO2  as  a  greenhouse  gas) and  represents  approximately  half  of  all  HFC  use  in  the  U.S.  Many countries  already  use  or  require  the  use  of  low-­GWP  alternatives  to  HFCs, e.g.,  an  estimated  one  billion+  refrigerators  in  the  EU  and  Asia  run  on hydrocarbons  (GWP  <25)  rather  than  HFCs.   Although  hydrocarbons received  EPA  approval  for  use  in  the  U.S.  in  January,  no  timetable  has yet  been  established  to  require  their  use  in  domestic  refrigerators  and freezers  or  retail  stand-­alone  coolers  and  freezers.”

Another Happy DynaCycle Cylinder Customer

Cylinder  Design Saves  Time  &  Money

 “Today  I  received  a  call  from  Randy  in  the Billings  branch.  His  customer  Chris  with  Empire Heating  &  Cooling  reported  back  that  the  new recovery  cylinder  is  faster.  He  said  a  recovery job  that  used  to  take  them  1  1/2  -­  2  hour  took only  45  minutes!  He  is  so  pleased  that  he  has now  purchased  another  cylinder  because  the time  saved  reclaiming  saves  him  more  money  in labor  than  the  cost  of  the  cylinder.”
