This flight incurred a rerte over the atlantic ocean and due to a known software problem with the B777; I was unable to send an updated flight plan to the flight deck and I was unable to cut-north-paste; our back-up method; as well. The crew needs to be able to xchk their rerte in their FMC with a flight plan produced by dispatch to prevent gross navigation errors. The reluctance of management to solve this problem needs to end. Financial economics is no excuse to ignore safety. Callback conversation with reporter revealed the following information: reporter stated this software problem has existed for years and it is time to get it fixed. When two or more B777 aircraft need new flight plans sent while over the atlantic; the time required can easily exceed the time available to send the data.

Narrative: THIS FLT INCURRED A RERTE OVER THE ATLANTIC OCEAN AND DUE TO A KNOWN SOFTWARE PROB WITH THE B777; I WAS UNABLE TO SEND AN UPDATED FLT PLAN TO THE FLT DECK AND I WAS UNABLE TO CUT-N-PASTE; OUR BACK-UP METHOD; AS WELL. THE CREW NEEDS TO BE ABLE TO XCHK THEIR RERTE IN THEIR FMC WITH A FLT PLAN PRODUCED BY DISPATCH TO PREVENT GROSS NAV ERRORS. THE RELUCTANCE OF MGMNT TO SOLVE THIS PROB NEEDS TO END. FINANCIAL ECONOMICS IS NO EXCUSE TO IGNORE SAFETY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THIS SOFTWARE PROBLEM HAS EXISTED FOR YEARS AND IT IS TIME TO GET IT FIXED.
