Don't know how it works in today's world, but when JMB was alive, it was like this:
His handgun designs were sold to Colt's for sales in North America, and Fabrique Nationale for sales in the UK and Europe. The rest of the world was fair game for both of them to compete.
When JMB finished a design, it was sent to Colt's, who was contractually obligated to file and pay for any handgun patent from JMB in the US. Then it was sent to FN, who was to file and pay for patents in UK and Europe.
JMB (before his handgunning years, I guess) designed MANY lever action rifles and various shotguns and sold the designs to Winchester. When he brought the Auto-5 to Winchester, but wanted royalties instead of an outright purchase, Winchester didn't go for it. So JMB packed it up and went straight to FN, who was more than happy to pay him royalties for the right to manufacture the world's first automatic shotgun. (What was Winchester thinking?
)
What both FN and Colt's decided to do with JMB's designs was another matter: FN never got anywhere with the 1911 design because, being in Europe, just as they were about to pump out a 1911-alike in 9.85mm, WWI struck. The same thing ALMOST killed the Hi Power at the dawn of WWII. Colt's never was interested in the Hi Power design, even though they were provided a pistol and plans by FN, as they were too interested in the 1911. I guess that would be a perfect example of divergent evolution.
I don't know anything about Winchester lately, but it is kind of interesting that there haven't really been anything new (handgun wise) from FN or Colt's of note since JMB's designs have been developed to the furthest extent.

EDIT: Totally forgot all about Browning Arms Co. They were the importers of the HP in North America. They were independent until they were bought out by FN sometime in the nineties. Now, both Browning (FN in disguise) and FN themselves import the HP with their own markings.
