Bought this on E-Bay since I'm apparently a sucker for open combs lately. The seller calls it a Tech, since it's in a Tech box,
What is it really? Looks different than my other Old Types. View attachment 1014854 View attachment 1014857
A reissue patent number is when, in effect, a revised patent is issued to correct a significant error to a product which previously was issued a patent number. For example, a competitor may sue to invalidate the original patent. The patent holder then can attempt to get the patent reissued by making the necessary legal corrections. If successful, the Patent and Trademark Office can reissue the patent.
