On a jigsaw puzzle piece, there is a number of ... but is rather formed during injection molding of the piece.()

Anyway, for patent writing, you must be able to find earlier similar patents?

Well, hopefully not.

I finally decided to call the female and male parts of the joint "mortise" and "tenon" respectively.

But that's just what they aren't, in a conventionally formed puzzle. A tenon slides out of a mortice, as well as into it. You can define black as white if you want, but it tends to get in the way of your reader's understanding.

Are there dedicated designations for the lobe-shaped protrusion and the complementary cut-out of a jigsaw puzzle piece???

Er... Outies and innies? Yangies and yinnies? Plugs and sockets? Doctors and nurses?

On those rare occasions when I've been bothered by the jigsaw bug, I've found myself making a lot of references to "ears" and "shoulders"...maybe it's just me..r

In a mechanical engineering application, that's exactly what I would call the members of such a joint. The terms "mortise" and "tenon" go beyond cabinet making.
Both words stem from French, "mortaise" and "tenon" (related to the verb "tenir": to hold or keep). Interestingly, the noun "mortaise" is a feminine one and "tenon" is a masculine one.

Pat Durkin offered Innies and Outies, too. I've never used those terms, but they seem pretty good. Innocent, even.
"Doctors and nurses" will get you nowhere but in trouble, of course. First, you have to decide which is which. Then you have to justify your decision. Then you have to explain to one of the groups that you are absolutely NOT being sexist. And while you're explaining, the other group will snigger.
Tabs and holes always worked for me. But now that we've started on the explicit male-female road, there's no going back. Everything will be either questionable, or embarrassing for kids, or too suggestive, or will get you called a Dirty Old Man (or Filthy Old Woman).

Jigsaw puzzles used to be such good, plain fun. But I doubt that any of us could face the puzzle pieces now without thinking about... well, you know..

I suggest that a patent jury could be misled by a jigsaw patent that implies the pieces hold together by mortise and tenon joints - unless they do, in this new invention.

Obviously safer to follow Donna's neutral road where it's OK to announce "I need a knob with a bit of white at the tip." Unless that's only allowed if an actress or a bishop is on the team.

There are MT joints that only go in, never out, but another small peice is required the wedge (or wedges)
