Selmer Stamped Patent Numbers

Having looked at quite a few eBay pictures for Mark VI altos (as one does :) ), I became curious as to which patents Selmer actually held that were so important that they felt the need to stamp them on every single horn they produced. The first two listed here are what you might expect: a patent for the linkage on the left hand key cluster, and a patent for the octave key.

U.S. Patent 2710558 http://pdfpiw.uspto.gov/.piw?Docid=02710558&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO1%2526Sect2%3DHITOFF%2526d%3DPALL%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsrchnum.htm%2526r%3D1%2526f%3DG%2526l%3D50%2526s1%3D2710558.PN.%2526OS%3DPN%2F2710558%2526RS%3DPN%2F2710558&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page

U. S.

This patent number, though, appears on Mark VI horns of earlier vintage (it's not on my 1974 horn, not sure when they stopped stamping it), and doesn't seem to relate. Did Selmer stamp a wrong patent on their horns for 20 plus years?

U.S. Patent 2940640 http://pdfpiw.uspto.gov/.piw?Docid=02940640&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO1%2526Sect2%3DHITOFF%2526d%3DPALL%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsrchnum.htm%2526r%3D1%2526f%3DG%2526l%3D50%2526s1%3D2940640.PN.%2526OS%3DPN%2F2940640%2526RS%3DPN%2F2940640&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page

Is anybody on here a patent attorney :) ?

I'm not a patent attorney (nor any other sort of attorny for that matter) but I have noticed this as well.
From what I have seen, this patent number (2940640) appears on Altos and Tenors between 62k and 170k.
I have not seen it on any baritones (even though other patent numbers are listed on the baritones).

I've often thought about this. Taking a very blind guess-I reckon one of the patents would be for the tilting low Bb spatula. Logic is in my favour here,because, around the time the patent numbers disappeared-expired?-Yamaha and very soon everyone else inc. Keilwerth etc. started putting tilting Bb spats on their pro horns. Within a few years the 'whole cheapo' Selmer clones started to appear from all corners of the globe. Only a theory I know but, feasible..............don't ya think??
