Herbert Haddan & Co. was a British patent agent firm which gave its address as 18, Buckingham St., Strand, W.C., London, in 1896;[1] and 31 & 32 Bedford St, Strand, W.C., London.[2]
The founder must have been Herbert John Haddan, who also patented in the aero field.
Reginald Haddan also filed patents for this firm ; might have been Herbert's son.
Seems disproportionately associated with patents about ballonets.
