H. Bœttcher fils

H. Bœttcher fils was a team of French patent agents, perhaps H. Bœttcher and his sons, or possibly only the sons. There is a fair likelihood of H. Bœttcher having a direct connection to Bœttcher and Kapp, who were active approximately one generation earlier. H. Bœttcher fils were mainly active between 1910 and 1915, to the best of our knowledge thus far.
