Hi my name is David and I would like to relay to you all the mine-field that is inventing! and how if you are not careful like I was not you can give away your cherished invention/innovation!
My true story starts in January 1995, with my innovation that I had kept under my hat since the the 1970's, frustrated I contacted numerous Electrical Manufacture's with only one 'Crabtree Electrical Limited' expressing interest, after a number of letters between my self and their Technical Director they asked me to sign their NDA which I did and they then requested as to 'what was my innovation'
I then sent a specification and a sample. Later the director wrote to sat it was not an invention and already in use in 'South Africa' it was notable that in the last paragraph he stated.....
Quote.
'I must confess my surprise that to the best of my knowledge, no UK manufacturer has applied the principle to a 13 amp plug'
End quote!
Well by now you no what the 'INNOVATION' is appertaining to the BS 1363 13Amp domestic plug, but not what it entailed? so let me enlighten you, it was to simple for obvious reason's to make it completely CLEAR, TRANSPARANT.
Let me make it clear I am not accusing 'Crabtree Electrical Ltd' of anything criminal or underhand, No I am just reporting on the facts which can be verified by the original documentation!
So let me say what my latter-day investigations have revealed.... End of March beginning of April 1995 applications for a number of certification was made in Ireland BS 5733-IS 401-SS145 subsequently granted, company unknown! And in 1997 PMS a manufacturing company in Singapore manufactured the exact same specification that I introduced to 'Crabtree Electrical Ltd' back in March 1995, again I am not accusing any one company or person of wrongdoing but informing you of the very real need to seek the sanctuary of a 'Patent'
