-
Please note that the actual date of manufacture can be
quite different from the patent number as products were oftentimes
produced for a number of years after they were first granted a patent.
-
English patent numbers for some unexplainable reason
always began with the number 1 at the beginning of each year.
-
Zip codes were first introduced in 1962.
-
Items with "patent applied for", "pat app'd for", "pat'd",
etc. may not be and are virtually impossible to look up on charts like
the above.
Additional Informational Links
Here is the link to the US Patent office website where you
can, if you have the patent number, pull the patent papers pretty easily.
With only the date it becomes a more involved process and you can find out
information about doing it there. Also please note there are
instructions on the site for downloading the tiff program that you will
need to view the patent files.
http://www.uspto.gov/
or
Here is the link to Google's Patent Search.
http://www.google.com/patents It is VERY
user friendly. Play with it to find the patent for your piece, or
for a fee I will do it for you if you have the Patent Date, Number,
Location, Patentee's name, and / or combination of the above and do not
have the time or inclination.
