Growth in the IP lawsuit sector of the economy and the resulting patent-reform movement can leave you thirsting for reliable data on which to base policy judgments and cocktail-party conversation. Initially, I thought the IEEE Spectrum's annual patent stats roundup, Keeping Score in the IP Game would handily rehydrate my chit-chat cortex. After all, the data contains glittering--although frequently unsurprising--infonuggets like:

A federal judge has temporarily blocked the U.S. Patent and Trademark Office from enforcing new rules that would impose some roadblocks on patent applications.

The rules, scheduled to go into effect on Thursday, were designed to encourage greater specificity in patent applications and curb subsequent patents that are related to the original, a practice called "continuation applications."

Critics of the current rules say continuation applications have been abused, and that the system is overburdened, and have generally supported the Patent Office's move. For its part, the office says the changes would help to reduce a backlog … Read more

Two of the world's largest PC makers still can't seem to get along.

Acer is suing Hewlett-Packard again for patent violations. It's an escalation of the battle over the two companies' intellectual property that began earlier this year.

Filed in a U.S. District Court in Wisconsin and with the U.S. Internaional Trade Commission Tuesday, Acer said it is countersuing HP for infringing on its patents related to servers, PCs, and peripheral devices. HP declined to comment on Acer's suit.

HP initiated the fight in March when it sued Acer over five patents involving read/… Read more

A month ago, Network Appliance sued Sun Microsystems, alleging the server and software company's ZFS file system infringes seven NetApp patents. Sun on Thursday fired back with a suit that claims NetApp violates 12 of Sun's.

Sun's suit also argues that NetApp's patents are invalid and that it doesn't infringe them anyway. And it requests an injunction prohibiting the company from selling any products that infringe Sun's patents.

Patent suits are often expensive and acrimonious proceedings, and they're particularly unpleasant when fought among Silicon Valley rivals who often share mutual customers and sometimes … Read more

A day after Sun Microsystems Chief Executive Jonathan Schwartz said his company will sue to have Network Appliances' file-server products removed from the market, NetApp's founder Dave Hitz brushed off the threat and took issue with Schwartz's open-source reasoning.

"This sounds like Sun's broad threats when they sued Azul, but in the end, Sun didn't put Azul out of business or even stop them from shipping products. I'm quite confident that two years from now--or however long it takes this suit to reach court--NetApp will be doing just fine," Hitz said in a blog posting … Read more

Vonage said Thursday it had resolved an ongoing patent dispute with Verizon Communications at a price tag of up to $120 million, ending what has been a mostly gloomy saga for the struggling Internet phone company.

The announcement comes about a month after New Jersey-based Vonage, which has yet to turn a profit, lost the bulk of an appeal regarding three voice over Internet protocol patents held by the nation's second largest telephone company.

The appeals court upheld a jury finding that Vonage had infringed on two patents that are arguably … Read more

SanDisk is suing 25 companies for infringing on its patents on removable flash storage devices.

The flash memory maker filed a suit with a U.S. District Court in Wisconsin and another with the U.S. International Trade Commission Wednesday evening, seeking damages, a permanent injunction and an order from the ITC banning the importation of the products.

The European Union may have unwittingly played into Microsoft's anti-open source hands in its recent ruling. While initially met with cheers from the open-source community, the ruling has many, including Red Hat's counsel, Michael Cunningham, suggesting that all that glitters is not gold:

Updated at 2:31 p.m. PDT: Sun Microsystems plans to countersue Network Appliance later this week, Chief Executive Jonathan Schwartz said Wednesday, a suit that will include a request to remove the company's products from the market.

Schwartz said on his blog that he has "no interest whatever in suing them" and therefore "reached out" to Chief Executive Dan Warmenhoven. But, he said, NetApp's demands--that Sun "retract" its ZFS file system from open-source community and restrict its use to computing and not storage devices--can't be met.

Consequently, "Later this … Read more
