How Much Oatmeal is too Much in a Stout?

I should elaborate that I've made that same malt bill numerous times, and the oat slickness occurred in maybe 25% of them. It was my standard for single hop IPAs, so I'm very familiar with it. A couple of the beers had the slickness age out but not all of them

Maybe that is the reason for my different experiences with oats. Maybe some oats have more beta glucan? Or maybe some off the yeasts just chop it up?

According to a news paper report on the patent case it seems the judge upheld the Rose & Wilson patent as having come first before Alloa...

It was one of those cases where Rose won the argument, but the judge created a massive loophole which meant that Maclay were able to carry on as before. Maclay were only prevented from brewing 100% oatmalt beers (which they didn't want to do, but you make the patent claim for the 100% case and then broaden it), but they were still allowed to brew mixed oat/barley beers. If Rose's patent had been watertight, then they would have been able to stop Maclay doing that.

It gives some interesting context to Mackeson's ruthless enforcement of milk stout patents a few years later.
