De-sta-co Clamps
looking at this EDN Design Idea:

The thing that caught my eye was the clamp - the article calls them:
Lever arm-toggling ? Really ? In the olden days of the 1970s/80s/90s we called them: De-Sta-Co clamps because that's what was stamped into the clamp :) I imagine that there are many generic versions now. In our receiving inspection department they were used for holding a device-under-test (DUT) in place on a test fixture. With ICs this wasn't necessary but with other items it was required to hold the DUT in place to minimize affecting the temperature or whatever.

I wonder if Destaco ever considered doing what Louboutin did with their shoes - Destaco clamps always had red handles :)

Trademarks last FOREVER unlike patents or copyrights - although the holder does have to defend the trademark and keep up any required renewals.
Examples from pre and post Watergate: Daniel Ellsberg used a Xerox copier to copy the Pentagon papers. People referring to the Pentagon papers in public as "Xeroxed" would have been contacted by Xerox and chastised. Similarly I remember watching the Senate Watergate hearings, Senator Ervin made the remark: "we'll Xerox you a copy". Xerox contacted Senator Ervin's office about this and he mentioned it in a subsequent hearing :)
Also I remember when my Dad subscribed to Writer's Digest, one of the issues would address incorrect use of trademarks in published writing as a potential no-no. And a lot of major companies would advertise in that issue to emphasize that writers shouldn't take liberties with their trademarks.
The idea is to prevent the trademark from becoming a generic reference for some particular item or action.

I imagine if the author of that EDN Design Idea was talking about Louboutin shoes he'd say something like: "red-soled womens shoes with insanely high heels" :)
