The French Patents of Phonographic
Industry
4241 patents related to phonograph, cylinder,
recording and reproduction of sound,
between 1857 and 1934,
at the Institut National de la Protection Industrielle (French Patent Office).
The
two following tables contain each four columns :
Patentees (legal
entities or companies),
Patent number,
Short description,
usually one sentence, in French
Year of issue
in the INPI Bulletin (former BOPI : Bulletin de l'Office de la Protection Industrielle).
Attention, this is not the date issue of the patent itself.
I will provide this in the future, in an updated document,
when data processing will be completed and verified.
These
tables show simply the same datas in two manners :
1° : A sorting
of the patents by the alphabetical order of the patentees. Click
here.
2° : A sorting
of the patents by the alphabetical order of descriptions Click
here.
This second sorting could be replaced in the future by a more
relevant index of themes, with keywords (like : "horn, motor, reproducer,
wax formula", etc.), which will be contained in an additional column, in
French and English. These documents are under PDF (portable document format),
readable with the freeware Adobe Acrobat. To
download here if not yet installed on your computer.
Two
possible uses :
1° : These
tables are ready to print. One can print a first file on a pile of sheets in
recto, then use the back for the second document. You get thus a 226 pages reversible
printed paper form on 113 sheets (if you do not make use of A4 size, you will
need to configure before printing).
2° : One
can simply "browse" on screen with the tools "following page",
"preceding page ", etc of Acrobat. This makes possible to
operate a research in full text, with the "Search" option (represented
in Acrobat by a pair of binoculars). For example, by typing the word
"pavillon" (which means "horn"), one can find all descriptions
containing this word.
After having found the seeked patent, it is possible to consult it at the INPI , or even at you national Patent Office. One can order a photocopy of it for a moderate amount at the INPI in Paris. For more infos: www.inpi.fr
This work tends to exhaustiveness, but nothing is never perfect. Your comments are welcome. Current version: n°1, updated June 24, 2003. Classification by patentee here. Classification by descriptions here. Happy hunting!
