Re: [FWDLK] Bendix Electrojector

[Dave Casey <dcasey@xxxxxxxxxxxxx>]

Okay, so I got bored.

    The trademark "Electrojector" was twice registered with the US PTO. The
first filing was 4 January 1957, registered 27 August 1957.
It was registered by Bendix Aviation Corporation in Detroit as "Goods &
Services: Fuel injection systems for internal combustion engines. First use
was 16 NOV 1956. The registration included a typed drawing (not to be seen
online). Last listed owner is Facet Enterprises, Inc. in Tulsa which is a
spin off of a Bendix/Fram conglomerate, now known as Purolator (sound
familiar?), owned by Penzoil (sound more familiar?). See Purolator's website
for a more detailed version of how they ended up with the rights to the
Electrojector. Bendix bought Fram and got sued for it, so they had to spin
off a company for filter products or something.
    Bendix filed a sort of "secondary" trademark description under the
electrojector name ain February 1957, which now defines it as "Electronic
parts of a fuel feeding system - namely modulators, distributor-breakers,
amplifiers, and solenoid nozzles." First use is still 11/16/1956. This
trademark was registered in October 57 and also became property of Facet.
    Both trademarks were renewed once in 1977. Both are now expired and
considered "dead" by the US PTO.
    They have registration numbers and serial numbers, but these are
trademarks. The only way to search for a patent in the '50s online is by
patent number or current US classification. Any ideas?
