'Linux Defenders' aim at Microsoft patents

A Linux advocacy group on Tuesday said it is publicly seeking invention data that could help overturn three Microsoft patents that the software maker has charged are infringed by some implementations of the Linux kernel.

The Open Invention Network said it is looking for examples of so-called prior art that could help invalidate three file management patents that Microsoft used in its suit against GPS maker TomTom. Although TomTom and Microsoft settled, the suit raised the specter that Microsoft might pursue other Linux-related companies.

OIN encouraged those with examples of earlier work in the areas covered by Microsoft's patents … Read more

Qualcomm, Broadcom reach $891 million settlement

Qualcomm and Broadcom announced Sunday that they have agreed to end patent litigation between the companies worldwide, with Qualcomm paying Broadcom $891 million, according to the announcement.

On Wednesday, Qualcomm delayed its second-quarter earnings statement, citing advanced settlement discussions with Broadcom.

Qualcomm made this statement Sunday: "Qualcomm and Broadcom today announced that they have entered into a settlement and multi-year patent agreement. The agreement will result in the dismissal with prejudice of all litigation between the companies, including all patent infringement claims in the International Trade Commission and U.S. District Court in Santa Ana, as well as the … Read more

Apple patent hints at volume controls in Safari

Apple Insider has spotted a a newly released patent filed by Apple back in late 2007 that shows volume controls that can be integrated into various Web browsers. Described as a way to control "audio signals which may or may not be welcomed by the user" the patent depicts a new panel that sits in the top, right-hand corner of a user's browser and allows per-site controls over incoming audio signals. There's also a mute button that can cut out just the sounds from the browser entirely while leaving sound from other desktop applications untouched.

According to the patent, the key goal is to add a volume control overlay over sites that do not provide it, as well as a system that will remember the user's preferences between browsing sessions. This would be useful in Flash-heavy sites where the controls may be hidden away, or entirely absent. It would also let users create custom sound profiles, so you could have YouTube videos on your computer at work always start out at a low volume level, or your Internet alarm clock site always play at 100 percent.

The patent also describes situations where users can create specific rules that will change how audio can be played back based on whatever other applications are running. So you could theoretically set it to mute all your browser audio only when you're listening to music in iTunes, or using an audio-centric application like Skype, then bring the sound back as soon as you're not getting audio output from those applications. Apple has done something similar on the iPhone by interrupting music when you're getting a phone call, or slightly lowering the volume on notification sounds when you're using other apps.

What makes this patent filing notable is that it's not just for Safari, and is listed as being applicable to multiple browsers, which means it could either be a part of an upcoming OS or as a standalone application. As the usual disclaimer goes though, patents are often filed for technologies that never make it to market.

I've embedded the entire patent after the page break. (Thanks to Patents.com and Scribd for that.)

Update: Several readers have pointed out that Windows Vista has had a similar feature since its release called Volume Mixer that lets you pick out the maximum volume level for each application. However it's worth noting that in Apple's proposed implementation, the user would be able to control it on a per-site basis. … Read more

Innovation can breathe again: Patent filings decline

For those of us who believe that patents stifle innovation, this week brings good news: patent filings are down, as PatentlyO reports. After years of steadily increasing, U.S. patent filings have dropped, perhaps reflecting the bad economy.

Or perhaps an increase in common sense? Nah....

While the PatentlyO blog suggests this is a "crisis," I'm with TechDirt: the only crisis is that it has taken so long for patent filings to decline:

Considering the large number of bad patents that got through over the years, and the resulting flood of applications from others hoping to strike … Read more

Apple patent filings hint at iPhone evolution

Apple could be providing a glimpse into some new features for future iPhones in a couple of patent applications the company recently filed.

The blog MacRumors.com reports that Apple has published two patent applications in the past few weeks that focus on features that incorporate motion and gesture user interfaces. One patent was published two weeks ago. And the other one was published Thursday.

The iPhone already has an accelerometer that allows users to shuffle songs on the iPhone by shaking it. And the motion-detecting technology has also been widely used by application developers who have incorporated the functionality into games and other kinds of apps for the iPhone. But Apple appears to be moving a few steps further in making motion an even bigger part of interacting with the iPhone.

Apple notes in the first of the patent filings that interacting with mobile devices while also engaging in another activity, such as jogging or running, can be dangerous as users might be distracted while they're trying to advance to another song or answer a phone call. The new gesturing technology would try to solve this issue. According to the patent filing:

There is a need for providing a user interface in a personal media device that minimizes either or both a user's physical and visual interactions with the personal media device, especially while the user is performing other activities that require, for example, the user's visual senses.

An outline of patent problems--and solutions

Patents have become a minefield that inhibit software innovation, a fact recently highlighted for me in a conversation with Rob Tiller, Red Hat's vice president of Intellectual Property and assistant general counsel.

Many software patents are of poor quality and are difficult to interpret, Tiller explains, made worse by the fact that patent boundaries are often vague: a patent can even cover an invention the patent holder never conceived.

Compounding this morass, it's difficult to impossible to know if code you have written could be covered by a patent, as search methods are unreliable (and damages are structured … Read more

Sony patents PSP-controlled spy car

More goodies out of Sony's party bag of patents, this one involving a remote-controlled car that can be navigated using a PlayStation Portable.

While this seems to be merely exchanging the remote for a PSP and goes where cell phones have gone before, it does add an interesting dimension--a camera mounted on top. According to the patent, visual data from the camera is beamed back to the PSP so the user can navigate obstacles or record and save a movie. Which opens up possibilities such as spying on friends carrying out surveillance work. Or even turning this idea into … Read more

Next iPod to have metal unibody design?

According to Macnn, one of Apple's latest patents indicates the company may be looking at a unibody design for the iPod Classic--and possibly other products.

In October of last year, Apple began incorporating unibody designs into its new MacBook and MacBook Pro lines. The "revolutionary" manufacturing process creates a seamless enclosure carved from a single piece of aluminum that makes the final product lighter, thinner, and, according to Apple, sturdier. The unibody design may also help shave manufacturing costs.

It seems logical for Apple to switch to a unibody design for its iPod Classic, which currently uses … Read more

Top Microsoft strategist highlights a change in IP policy

Open source is not going away. Why should it?

That's a quote from Microsoft CEO Steve Ballmer in Marshall Phelps' new book, Burning the Ships, and it's a question that Phelps tries to answer.

In the course of doing so, Phelps portrays Microsoft as desperately striving to adapt to a new world of aggressive enforcement of intellectual property (IP), but ends up suggesting a rising IP hegemon eager to shape a new world of such enforcement.

It's not pretty.

Phelps is the man who turned IBM's patent portfolio into a $2 billion business (as he reminds the reader several times), but his goal at Microsoft wasn't to generate cash through licensing, he declares. Nor is Microsoft's new IP strategy a rehash of the old world where IP is treated as a negative right (i.e., the ability to protect one's IP from the wiles and avarice of competitors), but rather IP becomes "a bridge to collaboration with other firms."

But this is where the contradictions begin.

Phelps indicates that Microsoft cannot go it alone in the world...then points to statistics that claim 42 percent of the world's IT people depend upon Microsoft technology. Microsoft apparently has done quite well going it alone.

He further agonizes that Microsoft must expand its partnership footprint...even while identifying 640,000 vendors in Microsoft's partner ecosystem that earned more than $425 billion in revenue in 2007. It's unclear, based on his own evidence, how Microsoft is starving its partners and, indeed, Microsoft has always made much of what an impressive partner it is with 96 percent of its sales going through partners.

Phelps berates patent trolls and others for forcing Microsoft to pay hundreds of millions of dollars in licensing fees...but then goes on to explain how Microsoft's new IP strategy has his team on the road constantly signing up new licensees for patent royalties and other agreements.

The money quote comes from Nathan Myhrvold, a former Microsoft executive and arguably now the world's largest patent troll with his company Intellectual Ventures, who declares himself "shocked" by the actions of patent trolls who could "just go and buy a patent and then use it" against Microsoft.

Oh, the irony, given that this is a concise definition of Myhrvold's current business plan and, apparently, Microsoft's.

Indeed, this is where Phelps' IP strategy for Microsoft departs from its stated intent. Phelps writes:

...(I)ntellectual property should always serve the business, not be the business....Microsoft didn't need money (from its patent portfolio)--it had billions of dollars of cash in the bank. Instead, Microsoft needed to transform its relations with the rest of the industry and build collaborative relationships with other firms. So that became the focus of our new IP strategy.

This sounds impressive, and it would be if it accurately depicted how Microsoft has approached the industry with its IP. Instead, Microsoft has spent the past several years menacing the open-source community and others with the threat of its increasingly large patent portfolio, and now claims "more than 500 patent and technology collaboration deals with companies large and small around the world."

I say "menace" because Phelps nearly always talks about these agreements in light of Microsoft approaching a prospective IP "partner." If Microsoft's IP were needed to build such cooperative bridges, presumably more of these "partners" would be approaching Microsoft, rather than waiting for Microsoft's heavy knock on the door.

Novell, as Phelps highlights and which CNET recently noted, is an exception to this rule, having approached Microsoft.

As with Novell, Phelps routinely neglects to mention facts that might cast Microsoft's IP actions in anything less than a warm and glowing light. For instance, he talks up Microsoft's generous decision to share 30,000 pages of technical documentation, conveniently forgetting to mention that the action was spurred by its desire to get out from under the European Commission's antitrust eye. (It didn't quite work.)

But nowhere is Phelps' selective memory more illuminating on Microsoft's intentions for its new IP strategy than when discussing open source. Here Phelps outdoes himself, starting with his characterization of why Microsoft wanted to build a bridge to the Linux world:… Read more

Microsoft slapped with $388 million patent verdict

Microsoft was hit Wednesday with a $388 million verdict in a long-running patent infringement case.

In the suit, Uniloc alleged that Microsoft used its patented technology as part of the software giant's product activation methods. A federal jury in Rhode Island found that Windows XP, Office XP, and Windows Server 2003 infringed on a Uniloc patent.

Microsoft said that it will appeal.

"We are very disappointed in the jury verdict," Microsoft spokesman Jack Evans said in an e-mail. "We believe that we do not infringe, that the patent is invalid and that this award of damages … Read more
