Gearwrench was the first, decades ago. They [Apex Tool Group which owns GW among many other brands] own quite a few patents.
Decades? Really? Gearwrench's own history timeline in their #1400 catalog shows their first combination ratcheting wrench coming out in 1996.
I think if you do some research, a Taiwan company named high five has most of the ratcheting wrench patents, and then there's Kabo. Apex tool group is maybe a year old as a joint venture betwenn Danaher and Cooper. Hell, look on the back of Gearwrench packaging and they still refer to Gearwrench as part of Easco tools.
Matco was slinging US made proswing wrenches (the kind with the fixed boxed end on one side and a ratcheting boxed end on the other) for more than a couple of years before Gearwrench flooded the market.
But back to the subject at hand, Gearwrench offers a wide selection, a broad range of styles, and great customer service. However, I would recommend that you avoid the reversible sets sold by Sears and other big box stores because, they have the stupid capstop feature which is basicly a thin flat washer on one side of the wrench. It does keep your wrench from sliding past a fastener but, it also means you can't use a reverse grip on the wrench.
I would also look at the XL long versions of their wrenches in regular ratcheting and locking flexheads. They are simply made much better than those sets you see at sears that are on sale for half off. Buy the stubbies at Sears when they're half off but, skip the rest.
Gearwrench isn't the only game in town. There are great sets under the Blackhawk name. There are still a ton of SK G Pro wrenches floating around. EZ red is coming out with some interesting ratcheting wrenches after the first of the year. Matco and other tool trucks have a selection although somewhat pricey. It really depends on what feels good in your hands and what you work on. One thing is for sure though, once you start using ratcheting wrenches, you won't go back unless a ratcheting wrench won't fit. Forget about the idea of only having one set of ratcheting wrenches. That's like trying to eat only one potatoe chip.
