is a list of Edison's "phonograph and sound recording" patents from the
Edison Papers Project, including a few for 1913-19 not found in my list. Henri Chamoux's database of information on 4,241
French phonograph-related patents (1857-1934) and over 2,000 French
phonograph-related trademarks (1893-1940) may be found
here; you can buy his two-volume trademark compendium for
$110 from
Nauck's Vintage Records. Many European patents are viewable online via
DEPATISnet, maintained by the German patent office. And you can order Allen Koenigsberg's

Chronological List of U. S.
Phonograph Patents, 1913-1919 |

Compiled by

[You can also consult a
rough draft list of U. S. phonograph patents from
1878-1919 organized by current U. S. classification
here. I'm still in the
process of entering in all the relevant classification
descriptions.]
Patent texts are among the most significant official
documents associated with the history of phonography,
documenting a vast array of technical innovations—often
ingenious, and occasionally whimsical or bizarre.
All U. S. patents can now be viewed through the United
States Patent and Trademark Office website, so if you can
handle the stilted language and technical detail, these
valuable sources are readily available to you. Because Allen Koenigsberg's Patent History of the
Phonograph already contains much of the relevant
information for 1878-1912, I have prioritized the period 1913-1919, for which I
don't believe any
equivalent list has yet been published. This period
is also notable for the spike in phonograph-related
patents it witnessed:
nearly as many were issued in the
space of these seven years as had been issued during the
previous thirty-four! Click on any year in the column on the left to start browsing the
list. Once you're there, click on any patent number
to view the full patent through the USPTO website
(consult

What's included?
I have tried to include
every patent that explicitly suggests a phonographic
application—even if just in passing—or that appears from its design, assignment, or
other evidence to have been most probably intended for use in phonography.
Entries are arranged by issue date and, within each date,
by number, with regular patents preceding design patents. Next I have listed the name of the
patent, the name of the inventor, his or her place of
residence, any assignment details, the execution date (if
given), the file date, the original serial number, and any
divisions or renewals. Then, in italics, I've sometimes
included brief descriptions or excerpts from the patent texts,
mostly to show that a patent is in fact "phonographic" if this
would be unclear from the title. Finally, I have
included the current U. S. classification(s).
Important note:
the original serial number is often difficult to read because
it was printed in small type and often smudged, and I am sure
I have occasionally mistranscribed one. However, I have
felt it important to include these numbers, despite the
likelihood of error, because they are often used to
identify pending applications in other patent texts.

How was this list compiled?
I began by conducting a keyword search on
a set of phonograph-related terms through
Google Patents,
first covering the period 1878-1913 and later expanding
the search to include 1914-1919. I then determined
the current U. S. classification for each of these patents
and made a list organized according to these
classifications. Finally, I searched each seemingly
relevant classification in the list looking for additional
patents my keyword search had missed—carefully checking
each item along the way to make sure it did in fact fit my
criteria and wasn't a "false positive." In addition
to the 2,211 patents for 1913-1919, this procedure turned
up 2,254 patents for 1878-1912, which I compared against
the 2,144 patents listed in the updated 1991 edition of Koenigsberg's Patent History of the Phonograph.
Roughly 5% of the patents he lists didn't turn
up in my search; conversely, he doesn't list roughly 10%
of the relevant patents I identified for those years.
I take this as a sign that my list for 1913-1919
should be similarly comprehensive—but is presumably not complete.
(I'm also in the process of preparing a reference list of
patents from 1878-1919 organized by current U. S.
classification; see a rough draft
here.)Please

typos, incorrect links, or any other problems you may
