Palo Alto, Calif.-based Nest, maker of a “smart” thermostat and target of a patent-infringement lawsuit filed by industrial giant Honeywell, has submitted a formal response to Honeywell’s claims.

The start-up has also brought Richard “Chip” Lutton, a 10-year Apple Inc. veteran who managed the company’s patent portfolio, on board as vice president and general counsel.

In Honeywell’s suit against Nest, first filed in a U.S. district court in Minnesota on Feb. 6, Honeywell, maker of the iconic round thermostat, identified seven patents it believes Nest Labs infringes on with its Nest Learning Thermostat, a digital thermostat that came to market late last year. (You can read more about Honeywell’s complaint here.)

And now Nest has fired back.

“Nest does not use the Honeywell patents; but even if the patents covered what Honeywell alleges, they are hopelessly invalid. They are retreads — already invented by others years before …” the response reads.

Nest goes on to point out that specific patents — around remotely controlling temperature set-point marks, displaying temperature set points on an LCD inside a rotating ring, and presenting a user of an HVAC controller with “complete grammatical sentences” — are either indistinguishable from earlier Honeywell patents or aren’t worthy of a patent.

Chip Lutton, Nest's new vice president and general counsel.

The start-up does admit it was using Honeywell thermostats as research in its labs, stating, “Nest Labs admits that some Honeywell thermostats and/or boxes for Honeywell thermostats are shown in the photograph.” In the original filing, Honeywell references an AllThingsD video from last year showing that Nest Labs was examining “numerous” Honeywell thermostats in its research, indicating that Nest was aware of Honeywell’s contributions to the thermostat industry.

Despite the fact that Honeywell is an “industrial behemoth” with revenues that exceeded $36 billion in 2011, Nest says the company hasn’t innovated. “That ‘blah-looking controller’ on the market today is very often from Honeywell, which has long dominated the thermostat market, but has yet to generate a device that offers ordinary consumers as much as the Nest Learning Thermostat,” Nest claims.

Through the nature of its response and by bringing in Lutton, Nest doesn’t seem to be shying away from a battle with Honeywell, despite the David-and-Goliath nature of the fight.

Lutton’s departure from Apple was first reported last July, just as Apple was filing another complaint with the U.S. International Trade Commission, seeking a ban on the import of electronics and software made by rival HTC. That, of course, was just one complaint amid an ever-expanding web of patent lawsuits flying between Apple, Samsung, Motorola and Nokia, to name a few.

According to the Reuters report, Lutton is well-known in IP circles, and was once mentioned as a possible nominee for the Federal Circuit, which hears patent appeals.

And in 2012 — which also happens to be the 10th anniversary of the confab of tech and media titans — it’s already shaping up to be another fantastic event in terms of programming, with a lineup of onstage appearances that is sure to make some news.

There are many more very big names to come, but Walt Mossberg and I are pleased to introduce the first group of interviewees, which will give you a glimpse into the firepower we expect at D10 in late May. It is again being held in Rancho Palos Verdes, just south of Los Angeles.

The initial speakers we have confirmed so far include: New York City Mayor Michael Bloomberg; serial entrepreneur Sean Parker, who will appear with Spotify co-founder and CEO Daniel Ek; Zynga founder and CEO Mark Pincus; Federal Trade Commission Chairman Jon Leibowitz; LinkedIn Chairman and VC Reid Hoffman, who will appear with LinkedIn CEO Jeff Weiner; and Skype CEO Tony Bates.

It’s hard to imagine someone we have wanted to have onstage more than Michael Bloomberg, a man of many talents and interests. He’s known worldwide as the 108th Mayor of the City of New York. First elected in November 2001 (and again in 2005 and 2009), he is also one of the most compelling politicians in the U.S. today.

But Bloomberg is also a pioneer in terms of the business of digital news and information technology, having built a huge and groundbreaking media company and information service. Bloomberg (the company) has 310,000 subscribers to its financial news and information service, and more than 15,000 employees worldwide.

There will be a lot to talk about with him, from the upcoming presidential election to the state of our government to the future of innovation, news and technology.

Also sure to be voluble is Sean Parker, the legendary Silicon Valley entrepreneur who has been on the cutting edge of innumerable important digital trends of the recent decade. In 1999, Parker co-founded Napster, the controversial and industry-changing music service, at the age of 19.

He followed up with early contact information service Plaxo, and then shifted over to his critical involvement as founding president of Facebook in its early days as a start-up, an experience which was dramatized in the movie “The Social Network.” Parker continued to found and also invest in companies, from Causes to Spotify to his most recent, Airtime, a social video company that he is doing with his Napster co-founder Shawn Fanning.

Parker will be appearing onstage with Daniel Ek, another serial entrepreneur and technologist, who started his first company in 1997 at the age of 14. The Swedish native later co-founded online music phenom Spotify in 2006, with Martin Lorentzon.

The former CTO of Stardoll and founder of Advertigo leads a company that is changing the way music is delivered and consumed by fans, against a backdrop of intense change in the industry, succeeding even as a plethora of other services have stumbled.

Also a groundbreaker is Zynga CEO and founder Mark Pincus, yet another serial entrepreneur, whose latest effort in the online gaming arena has finally resulted in his biggest success. It recently went public, and now has a nearly $10 billion market cap.

Before founding Zynga in 2007, Pincus had already started three other companies: Push start-up Freeloader in 1995; automated tech-support company Support.com after that; and early social networking site Tribe.net in 2003.

(I met Pincus when he was at Freeloader in Washington, D.C., while writing a profile of him for the Washington Post, so I have enjoyed tracking his progress since then.)

Pincus is also an avid angel investor, with early stakes in Napster, Brightmail, Twitter and Facebook.

Reid Hoffman was another early investor in Facebook, along with many of Web 2.0’s most successful ventures. Well-known in Silicon Valley as an entrepreneur and VC, and recently dubbed the “start-up whisperer” by the New York Times (although I am not sure exactly what that means), he’s also chairman of LinkedIn, the business-networking service that also recently went public (at a $10 billion valuation, too).

He’ll appear with LinkedIn CEO Jeff Weiner, who started out life in Hollywood, but soon made his way to Silicon Valley as a top exec at Yahoo. After running its media division, Weiner spent a short time at venture firms before going operational again at LinkedIn.

What it takes to build and maintain momentum as tech companies move into more mature stages, as well as how the social networking space evolves, are among the many topics on tap for the pair.

The evolution of a start-up phenom — in this case, Internet telephony service Skype — will be among the topics covered by Tony Bates, who is now a president at Microsoft, which bought it last year.

As such, he is responsible, says the software giant in its description of his job, “for overseeing the company’s direction, strategy and overall mission to become a global communications service that will eventually reach billions of users.”

That’s a tall order for Bates, who came to Skype from a top job at Cisco. Bates has deep roots (or maybe, routing?) in the guts of the Internet, having done backbone-engineering strategy for Internet MCI. The U.K. native also holds nine patents.

Lastly, given all the activity we expect will happen between government regulatory agencies and tech companies over the next few years, we felt it was key to bring in FTC Chairman Jon Leibowitz. He has been at the FTC as a commissioner since 2004, but was given the top job by President Barack Obama in 2009.

Among his priorities, according to his bio, is “promoting competition and innovation in the technology sector through law enforcement and policy initiatives; and protecting consumers’ privacy — especially while they are using the Internet.”

Uh-oh!

Leibowitz knows from regulation, having served as the Democratic chief counsel and staff director for the U.S. Senate Antitrust Subcommittee from 1997 to 2000, where he focused on competition policy and telecommunications matters, as well as a similar stint at the Senate Subcommittee on Terrorism and Technology before that.

There will be a lot more speakers to come, of course. But, so far, we think D10 is off and running fast.

Yahoo shareholders felt a little giddier earlier this week, when it seemed as if the company had finally decided to make a deal with its Asian partners.

But the happiest crew might end up being the Silicon Valley Internet giant’s outside counsel, Skadden Arps — and especially Leif King, the fantastically named legal eagle who has been advising Yahoo on the deal.

That’s because today the Yahoo board approved continuing the negotiations to come to a final agreement over the stake, sources said, which should take six to eight weeks.

It’ll surely be happy holidays for billable hours!

As costly as the legal bills will be, if it all goes well, an Asian solution will mean one major problem solved, with a possible pile of cash and new assets coming in to Yahoo.

To get there, the company signed a term sheet earlier this week with Japan’s SoftBank to sell back all its holdings there, and with China’s Alibaba Group to sell off more than half its stake (moving from a 40 percent stake to a 15 percent one).

The deal values Yahoo’s total shares in both companies at about $17 billion.

While it gets a pretty accounting name — “cash-rich split “– the vehicle to unwind it all is essentially a complex tax dodge finally cooked up by the trio, in which cash, new assets and stock will be moved around until everyone gets what they want (except the U.S. government).

I would explain it — but I am on vacation, and would rather drink eggnog and sleep — so here is The Wall Street Journal’s version, which I like because it sounds like Alibaba and SoftBank are giving Yahoo a hugely loaded Starbucks card for Christmas:

“As envisioned in the scenario, Alibaba would create a subsidiary into which it would put several billion dollars of cash, plus an operating asset that Yahoo wants to buy using additional cash from Alibaba, almost like giving Yahoo a prepaid card for an asset of its choice, the people said.”

Everyone is hoping there will not be any hiccups in the deal, which has been spearheaded by Yahoo board member and Intuit CEO Brad Smith, and Jerry Yang, who is also the company’s co-founder and a major shareholder.

Alibaba CEO Jack Ma and CFO Joe Tsai, both co-founders of that company, were the point men for the Chinese company. And for SoftBank, it was its founder and CEO Masa Son and his main U.S. exec, Ron Fisher.

Now, said sources, Yahoo’s board is hoping to still keep the bids from a pair of private equity firms — Silver Lake and TPG Capital — alive.

While initially the focus on the action, the PE bidding for partial Yahoo stakes has recently been sidelined by the Asian deal.

Now, sources said, Yahoo is hoping the new infusion of cash and assets will allow it fend off shareholder unrest — stock buybacks and dividends, anyone — to solicit higher prices from the firms to make strategic investments.

Yahoo had considered the initial bids too low, as did some very pissed-off activist shareholders.

Still, it’s not clear if those firms will jack their offers now, although sources said Silver Lake is still interested in some sort of deal that would give it influence over remaking Yahoo.

Silver Lake and others think the long-troubled company could be revived with some effort, and become a much more lucrative Web property.

But those negotiations might run into roadblocks over who gets to pick leadership for the company. Yahoo has accelerated its efforts to hire a new CEO, after firing Carol Bartz in September.

The PE firms, who would buy a large stake in Yahoo, also have wanted some level of control, including CEO and board approval, in order to be able to make massive changes at the company to turn it around.

Wall Street seems to like the Asian part of the deal, at least, since it shows some sort of forward momentum at Yahoo, and from its often-lugubrious board.

Shares are up almost 7 percent in the last few days, although they are not popping as they might be, given that new valuations based on a successful Asian deal put the stock at a much higher price.

In other words, investors like what they see, but are watching and waiting for more.

“Google’s alarming admission last week–confirming it collected entire emails and passwords–only heightened our concerns about how and why this data was collected,” Blumenthal said, adding that he’d rather not “rely on Google’s explanations and assurances…to confirm the facts about how this happened and how consumers will be protected going forward.”

A wise move, I think, particularly given the way Google’s narrative for this particular cock-up has evolved over the past few months, from an outright denial in April to a backpedaling, embarrassing admission in May and finally an apology in October.

In April, an outright denial:

Writing in Google’s European Public Policy blog, Peter Fleischer, the company’s global privacy counsel, denies there was a privacy issue with Google’s Wi-Fi data collection practices. “Google does not store or collect payload data,” he says.

Google product manager Raphael Leiteritz reiterates this assertion in the company’s Submission to Data Protection Authorities that same day. “All data payload from data frames are discarded, so Google never collects the content of any communications,” he writes.

In an interview with the New York Times a few days later, Google spokesman Kay Oberbeck dismisses the privacy concerns of German officials, saying: “What we are doing is totally legal and is being done by other companies around the world….We did not mention the WLAN project during our discussions with data protection officials because it is not related to Street View.”

In May, an embarrassing admission…

Writing in Google’s official blog two weeks later, Google SVP Alan Eustace reveals that the company actually had been collecting payload data. “It’s now clear that we have been mistakenly collecting samples of payload data from open (i.e., non-password-protected) Wi-Fi networks,” he explains. “So how did this happen? Quite simply, it was a mistake.” Then there was this from Peter Barron, Google’s director of communications for Northern and Central Europe: “We didn’t want to collect this data in the first place and we would like to destroy it as soon as possible.”

…followed by some aggressive damage control and a downplaying of the issue:

Speaking at Google’s annual Zeitgeist Europe forum, Google CEO Eric Schmidt describes the payload data collected as inconsequential and excuses the company for its misstep, saying, “There was no harm, no foul.”

In June, an unsettling hypothesis:

Apologizing for the company’s mistaken collection of user data, a Google New Zealand spokesperson tells the Otago Daily Times that the information the company’s Street View cars intercepted might not have been as inconsequential as Schmidt claimed. “Our in-car WiFi equipment automatically changes channels five times a second,” she says. “That said, it’s possible that the fragments of data we collected could contain entire emails or other content if a user broadcast personal information over an open network at that moment.”

In October, some hard evidence, another embarrassing admission and a change of tack…

A few months pass, and then a Canadian Privacy Commissioner’s investigation reveals “that Google did capture personal information–and, in some cases, highly sensitive personal information such as complete emails.” Interestingly, in its report on the matter, the Canadian Privacy Commissioner’s office notes that while Google “does not intend to resume collection of Wi-Fi data through its Street View cars…[it does intend to] rely on its users’ handsets to collect the information on the location of Wi-Fi networks that it needs for its location-based services database.”

And then the Schmidtstorm:

Appearing on CNN’s “Parker Spitzer,” Google CEO Schmidt cavalierly suggests that folks worried about Google Street View invading their privacy should “just move.” Ironically, he says this on the very day that Google admits those cars captured more than just fragments of personal payload data and says it is “mortified by what happened.”

Schmidt apologizes for his remark the next day:

“As you can see from the unedited interview, my comments were made during a fairly long back and forth on privacy,” he says. “I clearly misspoke. If you are worried about Street View and want your house removed please contact Google and we will remove it.”

And a day later the FTC announces that it has concluded its inquiry into Google Street View, saying the improvements Google has made to its internal privacy practices have alleviated its concerns for consumer safety.

Meanwhile, Blumenthal’s investigation continues.

The justification for that request? A recent piece by New York Times business columnist Joe Nocera accusing TomorrowNow of “the most serious business crime you can commit” and suggesting that former SAP chief Léo Apotheker–who was recently named CEO of Hewlett-Packard– was well aware of it. “He may not have been directly involved in this brazen theft of intellectual property, but it defies belief to say he didn’t know about it,” Nocera wrote. “And he did nothing to stop it until it was far too late.”

A damning indictment, were it not for one problem: Nocera’s fiancée serves as director of communications for the law firm representing Oracle in its suit against SAP, a clear conflict of interest for the columnist and one that wasn’t disclosed when this article was first published. And for SAP, reason enough to demand an order preventing lawyers on both sides from discussing the case outside the courtroom.

“The episode involving the New York Times article–coupled with Oracle’s counsel’s refusal to eschew publicity efforts during trial despite recognizing that jurors may not heed a court instruction not to read press coverage–leads to this motion,” SAP’s attorneys wrote. “Referring to this copyright dispute as ‘the most serious business crime’ is inflammatory and, to the extent anyone credits the author, prejudicial. The same is true of almost any type of extrajudicial statements by counsel that a juror might read. The jurors should hear evidence and argument in court only; they should not be exposed to counsels’ extrajudicial repetition of, or spin on, the in-court evidence and argument.”

Arguments on the gag order are due tomorrow, with a ruling to follow sometime after that. Trial starts in a week, and with a witness list that includes Apotheker as well as his harshest critic, Oracle CEO Larry Ellison, it should be great fun to watch.

Looks like Sue was right, and the road to which he referred was a short one. The struggling telecom company has hired counsel to explore a bankruptcy filing, The Wall Street Journal reports. Nortel, well aware what such reports can do to investor confidence, insists that no such filing is imminent. The company does, however, acknowledge that it has engaged advisers to help it weather the current economic storm. Just who has Nortel hired? Word on the street says Lazard Ltd. and law firm Cleary Gottlieb Steen & Hamilton.

Grim news for Nortel, which has spent the past several years trying to recover from the general downturn in the telecom industry and a nasty accounting scandal. With apparently very little success.

In a statement Wednesday, the company said, “Nortel is hard at work reshaping the business to even better serve our customers. There are those who fuel negative speculation, but there are many more who believe that Nortel has put in place the necessary plans to strengthen our financial footing and reset our cost base.”
