Paul Blum

Paul Blum is a French patent agent who is beginning to factor into our data. We'll have more on him later. This page was initiated tangent to Louis Blériot. We have him acting among witnesses, along with Chas. P. Pressly, on Blériot's Patent US-1918-1441056, suggesting sustained administrative familiarity the patent family of Patent FR-1916-502839.

We have a Paul Blum acting among witnesses, along with H. C. Coxe, on Patent US-1911-1025941 of René Arnoux. This Coxe is fairly definitely Hanson C. Coxe, by far the most prevalent among American witnesses, particularly when acting in conjunction with French co-witnesses, and Paul Blum is the patent agent on Arnoux' Patent FR-1915-491253.
