Tim Porter may be a nice guy and all, but if it was Google with all those so-called bogus/lax patents he'd be up there talking about how the patent system is fine and the problem really is more that the enforcement process depends on endless litigation and how the determination of infringement needs to be more streamlined.
He's a lawyer, his job is to be an advocate/mouthpiece for his employer's interests.
They (and most companies) play both sides of the fence. At the same time as saying how bad patents are for impinging on their products, they are buying as many companies with far-reaching patents as they can get their hands on -- "Our acquisition of Motorola will increase competition by strengthening Google’s patent portfolio", Larry Page.
You omitted the last half of that quote: "which will enable us to better protect Android from anti-competitive threats from Microsoft, Apple and other companies." What he was saying was that Google's new patents will increase competition by helping to prevent MS and Apple from shutting Android down, and I think his point is indisputable: Allowing MS and Apple to kill Android would reduce competition, so preserving android increases competition.
I truly don't think Google plays both sides of this fence; everything I've ever seen from Google's leadership decries the patent mess as a problem, and explains Google's own focus on acquiring and growing patents as a necessary evil. AFAIK (and I have paid attention), Google has never asserted any patents against anyone, except defensively.
I think Google really would prefer to change patent law and get rid of all these crap software patents -- or even all software patents, period. I think this is as much reflection of Google's arrogance as Google's altruism -- Google believes that given a level field they can beat the competition in any area they focus on. But I think there is actually a large dose of "good for society" thinking as well. You have to remember that fully half of Google's employees and nearly all of Google's management are software engineers, and the vast majority of software engineers think that software patents are bad for innovation, and software engineers love cool new technology. Google's engineers are no different all the way up to and including Sergey and Larry.
(Disclaimer: I'm a Google engineer, but all of the above is based on public information plus my perception of general attitudes within the company.)
Um, no duh! Of course Google would prefer to get rid of all patents. If you look at their business model it's all about 'ad revenue'. What do they care what software or hardware you run their ads on? The more software and hardware that hits their ads instead of other people's ads, the better.
So if they abolished all apple's patents (and everyone else for that matter) and people could make the best mobile device for free and not pay homage to any license (ie. java, or other), then there would exist more, cheaper mobile devices running android, and thus, hitting their ads.
So Google has nothing to loose and everything to gain if the patent system were dissolved over night.
