Jump to: navigation, search

We summarize in this page, grouped by manufacturers, all patents classified inside the wiki. Not all patents related to fountain pens or held by manufacturers are present here, as many have little historical interest and never went in production, or they apply to machineries, or other devices, or to ballpoint and pencils. We listed only those we found to be relevant for the historical information they contain or for the relationships that can be highlight.

For a list in chronological order by application date, see this page which is automatically kept in sync with this, as well with the other one ordered by publicaton date. A list ordered by inventors names is instead kept on this page.

For the compilation of the list have been an invaluable aid articles and instructions written by Antonios Zavaliangos on FPN (like those in this topic) which have been a starting point for further research.
