Slain Texas prosecutor remembered at memorial

TERRELL, Texas A Texas prosecutor gunned down outside his courthouse office last month was remembered Saturday for his zealousness in pursuing tough cases, love of flying and ability to tell stories.

Hundreds turned out in a school auditorium to celebrate the life of Kaufman County Assistant District Attorney Mark Hasse during a 90-minute memorial service that included stories about the veteran prosecutor's tough and softer sides as well as vows to catch his killer.

Hasse, 57, was shot multiple times the morning of Jan. 31 while walking from his car in a parking lot about a block from the courthouse. The brazen crime has sparked an investigation that includes both local and federal authorities, many of whom attended the Saturday ceremony.

Kaufman County District Attorney Mike McLelland described how Hasse, who wasn't married and had no children, never backed away from anything while often telling stories that brought laughter heard throughout the courthouse.

McLelland then turned to the effort to find Hasse's killer.

"He knows and I know there will be a reckoning," the DA said. "Too many people are focusing on that. That's not going to be a problem."

The slain prosecutor's brother, Paul Hasse, also mentioned the search for the gunman.

"You honor him by the massive effort you are making to find out who did this," he said.

Several speakers traced Hasse's career from his time as an assistant district attorney in Dallas in the 1980s to his decision three years ago to join the DA's office in Kaufman, 33 miles southeast of Dallas.

Dallas attorney Marcus Busch, who worked with Hasse in the Dallas DA's office, called Hasse "the consummate prosecutor," describing how he rose from handling cases in misdemeanor courts to being the chief of the unit charged with prosecuting organized crime. In one well-known instance, Hasse's "wicked and clever intellect" prompted him to take on a case of murder by arson that had previously been rejected, and he was able to gain a conviction, Busch said.

Busch also spoke of Hasse's love of flying and how he recovered from severe head injuries after the vintage World War II aircraft he was flying crashed in Virginia. Busch said he began taking flying lessons himself because of Hasse's passion for it.

Hasse left private practice to work as a prosecutor in Kaufman because "that's what his passion was," Busch said.

"I'd rather be in court trying a case with Mark than being in this room today," he said, stopping to gain his composure.

Cooke County DA Janice Warder, another former colleague from Hasse's Dallas days, recalled working with the prosecutor before computers put information at their fingertips. When questions would emerge from complicated autopsy reports or engineering documents, Hasse would have the answers, she said.

"Before there was Google, there was `Ask Mark,"' Warder said.

Above all else, Hasse was "ruthless when it came to fighting evil," she said.

Justin Lewis, an officer with the sheriff's department in Kaufman County who previously served as an investigator in the county DA's office, also spoke of how Hasse "enjoyed putting criminals in jail." Fighting to control his emotions, Lewis ended his remarks by saying the killer will be caught.

"Answers will eventually come," he said. "We must remain vigilant."

After Blizzard, Northeast Begins to Dig Out

The Northeast began the arduous process of cleaning up after a fierce storm swept through the region leaving behind up to three feet of snow in some areas.

By early this morning, 650,000 homes and businesses were without power and at least five deaths were being blamed on the storm: three in Canada, one in New York and one in Connecticut, The Associated Press reported.

The storm dumped snow from New Jersey to Maine, affecting more than 25 million people, with more than two feet falling in areas of Massachusetts, Rhode Island and New Hampshire. The Postal Service closed post offices and suspended mail delivery today in New England.

As the storm waned, officials in the hardest hit areas cautioned residents to remain indoors and off the roads to ease the clean-up.

Massachusetts was hard hit by the storm, with more than two feet of snow in Boston and even more in coastal areas. State police and national guard troops helped rescue more than 50 stranded motorists and even helped deliver a baby girl, according to Massachusetts Gov. Deval Patrick.

Patrick enacted the first statewide driving ban since the 1978 blizzard, which left 27 inches of snow and killed dozens. The ban was to be lifted at 4 p.m. today, the governor said.

However, Patrick cautioned residents to act with extreme caution even after the ban is over.

"Stay inside and be patient," Patrick said.

In Massachusetts a boy reportedly died of carbon monoxide poisoning as he helped his father shovel snow on Saturday, according to ABCNews.com affiliate WCVB-TV in Boston.

For residents along the coast, the waning snowfall didn't mean the end of the storm. Storm surges along the Massachusetts coastline forced some residents out of their homes Saturday morning.

"We've got 20-foot waves crashing and flooding some homes," Bob Connors on Plum Island told WCVB. "We have power and heat and all that. We just have a very angry ocean. In my 33 years, I've never seen the seas this high."

In Connecticut, Gov. Dannel Malloy declared a state of emergency and closed all roads in the state. The state police responded to more than 1,600 calls over the last 24 hours and the governor called up an additional 270 National Guard members.

"If you're not an emergency personnel that's required to be somewhere, stay home," Malloy said.

Overnight, snow fell at a rate of up to five to six inches per hour in parts of Connecticut. In Milford, more than 38 inches of snow had fallen by this morning.

In Fairfield, Conn. firefighters and police officers on the day shift were unable to make it to work, so the overnight shift remained on duty.

The wind and snow started affecting the region during the Friday night commute.

In Cumberland, Maine, the conditions led to a 19-car pile-up and in New York, hundreds of commuters were stranded on the snowy Long Island Expressway. Police and firefighters were still working to free motorists early this morning.

"The biggest problem that we're having is that people are not staying on the main portion or the middle section of the roadway and veering to the shoulders, which are not plowed," said Lt. Daniel Meyer from the Suffolk County Police Highway Patrol.

In New York, authorities are digging out hundreds of cars that got stuck overnight on the Long Island Expressway.

Bob Griffith of Syosset, N.Y., said he tried leave early to escape the storm, but instead ended up stuck in the snow by the side of the road.

"I tried to play it smart in that I started early in the day, when it was raining," said Griffith. "But the weather beat us to the punch."

Suffolk County Executive Steven Bellone said the snow had wreaked havoc on the roadways.

"I saw state plows stuck on the side of the road. I've never seen anything like this before," Bellone said.

However, some New York residents, who survived the wrath of Hurricane Sandy, were rattled by having to face another large and potentially dangerous storm system with hurricane force winds and flooding.

"How many storms of the century can you have in six months?" said Larry Racioppo, a resident of the hard hit Rockaway neighborhood in Queens, New York.

In New York, a little more than 11 inches fell in the city.

By this morning, New York Mayor Michael Bloomberg said nearly all of the primary roads had been plowed and the department of sanitation anticipated that all roads would be plowed by the end of the day.

"It looks like we dodged a bullet, but keep in mind winter is not over," said Bloomberg.

Data-wiping algorithm cleans your cellphone

Paul Marks, chief technology correspondent

Mailing your cellphone to a recycling company might make you a few pounds, but it can leave you at risk of identity theft. The deletion techniques recycling companies use are meant for hard discs, and so don't work on the solid-state flash memory used in mobile phones. That means personal data like banking info, texts, contacts and pictures can end up in the hands of, well, anyone the phone ends up with.  

To remedy the problem, British company BlackBelt Smartphone Defence of Skelmersdale, Lancashire claims to have developed a software algorithm that can securely delete data on cellphone memory chips. The trouble with data in a flash memory chip is that it is protected by an on-chip protection algorithm called the wear leveller. This hard-coded routine does its best to ensure the chip's lifetime is maximised so that each memory cell's ability to store charge is not worn out.

"The problem is that the wear-levelling algorithm ends up working
against the data wiping technique used for hard drives, which tries to
overwrite all the data,"
says the company's Ken Garner.

What the firm has done is write their own algorithm, called BlackBelt DataWipe, that works with,
rather than against, the leveller routine to render data
irrecoverable. "It is like having a shredder for personally identifiable
data," says Garner.

However, they don't yet know if their method is proof against sophisticated, nation-state level attacks - which might use electron microscopes
to read the last vestiges of the zeros and ones on a memory chip. "I imagine
if you're GCHQ you'll probably have technology that could get around
this and recover it in some way," says Garner.

Blizzard brings US northeast to a halt

NEW YORK: Planes, cars and trains came to a standstill across the densely populated US northeast Friday in the face of a blizzard raging from New York to Boston.

The storm was forecast to bring the heaviest snow so far this winter along the New England coast, threatening power and transport links for tens of millions of people.

By late Friday, New York, one of the world's busiest air travel hubs, was cut off from the skies as snow and wind led airlines to suspend all operations at LaGuardia, Newark Liberty and John F Kennedy International airports.

Tom Bosco, general manager of LaGuardia, told NY1 television that the airport was "battling" the storm and would strive to remain open even after the airlines shut down for the night.

He estimated that if a foot of snow fell -- the worst case scenario forecasted for New York -- flights would resume "probably by mid-morning."

The heaviest impact of the storm was expected overnight in and around Boston, and Governor Deval Patrick temporarily ordered all normal traffic off Massachusetts roads, with the threat of up to a year in jail for violators.

"There are a number of exemptions for... emergency workers and the like. Please exercise caution and use common sense," Patrick said at his emergency centre in Framingham.

In Connecticut, Governor Dannel Malloy issued a "ban on motor vehicle travel on limited access highways" to free up emergency services traffic.

Rhode Island, where some of America's most exclusive summer homes are located, also instituted driving restrictions.

In addition to the road and air snarl-ups, the rail service Amtrak said trains from New York northbound and also to the capital Washington, DC, were being suspended.

The storm came a little over three months after Hurricane Sandy devastated swathes of New York and New Jersey, killing 132 people and causing damage worth some $71.4 billion.

Snow began in light flurries across the region early Friday, but thickened and by Saturday was expected to leave depths of between half and one foot in New York and as much as two feet in Boston.

The National Weather Service warned that "in addition to the heavy snowfall, wind gusts of up to hurricane force are possible, especially near the coast. This will result in blizzard conditions with drifting and blowing snow."

On Friday night travel "will be extremely hazardous, if not impossible," the National Weather Service said.

Among the more glamorous victims of the travel upsets was designer Marc Jacobs, who said he had to reschedule his two shows at New York Fashion Week due to "the snow storm in the US and production problems."

New York Mayor Michael Bloomberg, who came under withering criticism for the city's flat-footed response to a blizzard in 2010, said residents should stock up with vital supplies and prepare for the worst.

"Stay off the city streets, stay out of your cars," he said at a news conference. "Staying off the streets will make it easier for city workers to clear the streets of snow."

New York's four zoos also announced they were closing for the duration of the storm.

"You can't take nature too lightly. Hopefully it won't be anything too drastic," Bloomberg said.

The good news was that the storm's peak was due as the weekend began, meaning far fewer people would be on the roads. Forecasters said the system should blow through on Saturday, with milder temperatures to follow.

Locals were comparing the coming storm to the ferocious Blizzard of 1978, which killed 100 people and buried Boston in more than 27 inches (68 centimetres) of snow and Providence, Rhode Island in nearly 28 inches (71 centimetres).

During that storm, people were forced to abandon cars stuck on highways and made their way around Boston on cross-country skis and snowshoes.

The making of a No. 1 song

Singer/songwriter Benny Blanco has produced some major hits by stars like Maroon 5, Rihanna and Ke$sha.

STORY HIGHLIGHTS

• A hit song could be a catchy earworm or a heartfelt ballad


• Top producer Benny Blanco says every song needs a hook


• Billboard expert says while albums aren't selling big, music is everywhere

(CNN) -- Don't ask music super-producer Benny Blanco to whip up a No. 1 song for an artist because it ain't gonna happen.

Sure, the man knows how to make hits: His work on Rihanna's "Diamonds" and Ke$ha's "Die Young" landed both at the top of the Billboard charts. But he's the first to tell you that trying to compose a chart topper is almost always guaranteed to fail.

"When you're like, 'Yo, we gotta write a hit song, we need a hit song right now," that never works," Blanco told CNN. "Every time that happens, I never write a hit song. I write a s****y song that sounds like someone trying to make a hit song."

Blanco knows of what he speaks. Two of the songs he helped produce are up for Grammys this year: Maroon 5's "Payphone," nominated for best pop duo or group performance, and Trey Songz's "Heart Attack," which is competing for best R&B song.

Blanco said in an era where singles rule (seriously, when was the last time you bought an entire album?) the pressure is on labels, artists and producers more than ever to produce a song that will head straight to the top of the charts.

But what does that song look and sound like? Is it an earworm such as Carly Rae Jepsen's "Call Me Maybe"? An intensely personal tale such as Adele's "Set Fire to the Rain" or a breezy "I can relate to that" poppy tune such as Taylor Swift's "We Are Never Ever Getting Back Together."

The answer is yes.

"Everything needs to be a hook," said Blanco, who snagged the Songwriter of the Year Award at the BMI Pop Awards in 2012 along with Ester Dean and Pitbull.

"Everything needs to be catchy because a listener is either going to stay with the song or lose interest in the first five seconds. But people also like those songs they can relate to and say, 'Yeah, I went through that.' "

Chris Mooney, senior director of artist promotions at TuneCore, said artists looking for a No. 1 song have to prepare their fans for a release by using every social media tool available: YouTube videos, tweets, Facebook postings, etc.

TuneCore distributes music for artists through partners such as iTunes and Spotify for a nominal fee. The company does not, he said, take a percentage of the revenue of the music distributed, and that business model has attracted such well-known acts as Nine Inch Nails, Ziggy Marley and the Civil Wars to use the service.

But if an artist wants to have a true No. 1 smash across the country, he or she will have to resort to some old-fashioned methods, Mooney said.

"You really need radio play, and that's not something everyone can do," he said. "But I still think that's key to having a No. 1 song."

That type of marketing to get airplay can be a pricey proposition. Just ask Sarah Stennett, an A&R executive and manager who works with singers Ellie Goulding and Jessie J. There are plenty of songs that are good tunes, Stennett said, but "when you've got a record that works, you need a record label that will then work that record."

But for a label to justify the expense of promoting an artist, the singer and song have to gel in a way that will connect with the audience, she said.

"There are certain songs that just encapsulate all you need to know about an artist," Stennett said. "They are like personality records. For instance, 'Get the Party Started' by Pink. It was a hit, but it also told you a great deal about who Pink was as an artist."

Stennett said the machine involved in promotion has to remain enthusiastic about the project.

"Everyone has to be about the message," she said. "It's about spreading the message. Have you heard this song by ...?"

Silvio Pietroluongo, director of charts for Billboard, said the conundrum the music industry faces is that while albums aren't selling nearly as well as before, the music is bigger than ever.

"I think music is more popular and accessible today than it's ever been," he said. "It's a major component of advertising campaigns, sporting events and anything multimedia."

That means the industry now has varying degrees of success, he said, from an artist such as Adele, whom he calls "lightning in the bottle" able to sell both singles and albums, to some such as Jepsen, who has sold millions of singles but not as many albums.

Pietroluongo said any artist is one hit away from that big break or even a comeback. But today's hit can easily come from performers such as Flo Rida, who, Pietroluongo said, is one of the all-time, top-selling digital download artists despite a lack of recognition as a hitmaker.

"They are catchy tracks," Pietroluongo said of the rapper's music. "I think the challenge with Flo Rida has been to put a face with the hits. I'm not sure if you locked 10 people in a room that half of them would realize that all the songs they love are Flo Rida."

Producer Blanco is also not easily recognizable, though he may increasingly be responsible for some of the most played music out these days. The process of putting it all together is as much fun as work, he said.

It often starts with a roomful of friends and lots of food. He likes to write with friends, he said, since as soon as he writes anything he usually shares it with them anyway. And a hit could occur while he's chilling in a hot tub or taking a walk: anything as long as the ideas keep flowing.

"I let the song come to me," he said. "Then that thing comes to you, and you just know what that thing is. Music isn't like a 9-to-5 job. You never know. It's just the most unpredictable thing."

Clamping down on prescription painkiller abuse

(CBS News) The Food and Drug Administration has called the abuse of prescription painkillers a "major public health challenge." On Friday, the FDA wrapped up a hearing on the drugs including oxycodone, Vicodin and Percocet. These painkillers do their job well -- but come with a big risk.

"My liver started shutting down," said 28-year-old Kimberly, who asked that we not use her last name. "My kidneys started shutting down. My thyroid level was through the roof."

Video: Health experts: Painkillers may cause headaches
Commonly used NSAID painkillers may be deadly for first-time heart attack sufferers

Kimberly nearly died from narcotic painkillers prescribed after a car accident. At first, she only needed one or two pills a day. But eventually she became addicted to the high.

"My tolerance started growing," she said, "and I started taking two at a time or three at a time. It grew to 15 at a time."

Kimberly is not alone. In 1999, there were about 4,000 opiate-related overdose deaths in the U.S. That figure more than quadrupled to 16,500 deaths in 2010.

"I knew that I needed to stop," Kimberly said. "I knew I did, but I couldn't bring myself to do it."

William Cope Moyers, a vice-president of the Hazelden Foundation, a drug treatment facility, said: "We are the most overly-prescribed nation in the world."

He said doctors need better education on the risks of addiction and non-narcotic options for pain treatment. Asked whether doctors are trained well enough in the management of chronic pain, Moyers said: "Clearly, doctors know the scourge of chronic pain, its legitimacy. But what they often don't know is how to deal with it with something other than writing a script."

Kimberly is in treatment at Phoenix House and has been drug-free for eight months.

"Who knows what's going to happen tomorrow? But I'll deal with that then," she said. "But today, I'm not getting high. And then tomorrow comes and I'll try the same thing."

So what are the possible solutions to the problem? The focus is on education. Patients think, 'This is a safe drug. After all, my doctor prescribed it, it's FDA-approved.' The FDA is trying to reverse that misconception. Then the White House is working to try to enact legislation so when doctors apply for that DEA registration that allows them to write the narcotics prescription, first they have to take a course that teaches them how to correctly use it.

'Stay Home': Northeast Shuts Down as Blizzard Hits

A blizzard of possibly historic proportions began battering the Northeast today, and could bring more than two feet of snow and strong winds that could shut down densely populated cities such as Boston and New York City.

A storm from the west joined forces with one from the south to form a nor'easter that will sit and spin just off the East Coast, affecting more than 43 million Americans. Wind gusts were forecast to reach 50 to 60 mph from Philadelphia to Boston.

Cape Cod, Mass., could possibly see 75 mph gusts. Boston and other parts of New England could see more than two feet of snow by Saturday.

The storm showed the potential for such ferocity that Massachusetts Gov. Deval Patrick declared a state of emergency Friday afternoon and signed an executive order banning vehicular traffic on roads in his state effective at 4 p.m. ET. It was believed that the last time the state enacted such a ban was during the blizzard of 1978. Violating the ban could result in a penalty of up to a year in jail and a $500 fine.

"[It] could definitely be a historic winter storm for the Northeast," said Adrienne Leptich of the National Weather Service in Upton, N.Y. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."

Airlines began shutting down operations Friday afternoon at major airports in the New York area as well as in Boston, Portland, Maine, Providence, R.I., and other Northeastern airports. By early evening Friday, more than 4,300 flights had been cancelled on Friday and Saturday, according to FlightAware. Airlines hoped to resume flights by Saturday afternoon, though normal schedules were not expected until Sunday.

Winter Storm to Hit Northeast With Winds and Snow Watch Video

The snow fell heavily Friday afternoon in New York City and 12 to 14 inches were expected. Mayor Michael Bloomberg said clearing the roads was his main concern, and the city readied 1,700 snow plows and 250,000 tons of salt to clear the streets.

New York City was expecting up to 14 inches of snow, which started falling early this morning, though the heaviest amounts were expected to fall at night and into Saturday. Wind gusts of 55 mph were expected in New York City.

"Stay off the city streets. Stay out of your cars and stay at home while the worst of the storm is on us," Bloomberg said Friday.

Connecticut Gov. Dannel P. Malloy declared a state of emergency, deploying National Guard troops across the state to assist in rescues and other emergencies. Schools and state courthouses were closed, and all flights after 1:30 p.m. at Bradley Airport, north of Hartford, Conn., were cancelled. The state's largest utility companies planned for the possibility that 30 percent of customers -- more than 400,000 homes and businesses -- would lose power.

PHOTOS: Northeast Braces for Snowstorm

Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today.

"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.

On Friday, Menino applauded the public's response.

"I'm very pleased with the compliance with the snow emergency," he said. "You drive down some of the roadways, you don't see one car."

As of 4:30 p.m. Friday, 837 National Guard soldiers and airmen under state control had been activated in Connecticut, Massachusetts and New York in anticipation of the storm -- 552 in Massachusetts, 235 in Connecticut and 50 in New York. The extra hands were helping with roadways, transportation, making wellness checks on residents and other emergency services.

Beach erosion and coastal flooding is possible from New Jersey to Long Island, N.Y., and into New England coastal areas. Some waves off the coast could reach more than 20 feet.

Blizzard warnings were posted for parts of New Jersey and New York's Long Island, as well as portions of Massachusetts, Rhode Island and Connecticut, including Hartford, New Haven, Conn., and Providence. The warnings extended into New Hampshire and Maine.

To the south, Philadelphia was looking at a possible 4 to 6 inches of snow.

In anticipation of the storm, Amtrak said its Northeast trains would stop running this afternoon.

Robot inquisition keeps witnesses on the right track

MEMORY is a strange thing. Just using the verb "smash" in a question about a car crash instead of "bump" or "hit" causes witnesses to remember higher speeds and more serious damage. Known as the misinformation effect, it is a serious problem for police trying to gather accurate accounts of a potential crime. There's a way around it, however: get a robot to ask the questions.

Cindy Bethel at Mississippi State University in Starkville and her team showed 100 "witnesses" a slide show in which a man steals money and a calculator from a drawer, under the pretext of fixing a chair. The witnesses were then split into four groups and asked about what they had seen, either by a person or by a small NAO robot, controlled in a Wizard of Oz set-up by an unseen human.

Two groups - one with a human and one a robot interviewer - were asked identical questions that introduced false information about the crime, mentioning objects that were not in the scene, then asking about them later. When posed by humans, the questions caused the witnesses' recall accuracy to drop by 40 per cent - compared with those that did not receive misinformation - as they remembered objects that were never there. But misinformation presented by the NAO robot didn't have an effect.

"It was a very big surprise," says Bethel. "They just were not affected by what the robot was saying. The scripts were identical. We even told the human interviewers to be as robotic as possible." The results will be presented at the Human-Robot Interaction conference in Tokyo next month.

Bilge Mutlu, director of the Human-Computer Interaction Laboratory at the University of Wisconsin-Madison, suggests that robots may avoid triggering the misinformation effect simply because we are not familiar with them and so do not pick up on behavioural cues, which we do with people. "We have good, strong mental models of humans, but we don't have good models of robots," he says.

The misinformation effect doesn't only effect adults; children are particularly susceptible, explains the psychologist on the project, Deborah Eakin. Bethel's ultimate goal is to use robots to help gather testimony from children, who tend to pick up on cues contained in questions. "It's a huge problem," Bethel says.

At the Starkville Police Department, a 10-minute drive from the university, officers want to use such a robotic interviewer to gather more reliable evidence from witnesses. The police work hard to avoid triggering the misinformation effect, says officer Mark Ballard, but even an investigator with the best intentions can let biases slip into the questions they ask a witness.

Children must usually be taken to a certified forensic child psychologist to be interviewed, something which can be difficult if the interviewer works in another jurisdiction. "You might eliminate that if you've got a robot that's certified for forensics investigations, and it's tough to argue that the robot brings any memories or theories with it from its background," says Ballard.

The study is "very interesting, very intriguing", says Selma Sabanovic, a roboticist at Indiana University. She is interested to see what happens as Bethel repeats the experiment with different robot shapes and sizes. She also poses a slightly darker question: "How would you design a robot to elicit the kind of information you want?"

This article appeared in print under the headline "The robot inquisition"

It's all about how you say it

When providing new information, rather than helping people recall events (see main story), a robot's rhetoric and body language can make a big difference to how well it gets its message across.

Bilge Mutlu of the University of Wisconsin-Madison had two robots compete to guide humans through a virtual city. He found that the robot which used rhetorical language drew more people to follow it. For example, the robot saying "this zoo will teach you about different parts of the world" did less well than one saying "visiting this zoo feels like travelling the world, without buying a plane ticket". The work will be presented at the Human-Robot Interaction conference in Tokyo next month.

Microsoft wins latest round in Motorola patent case

SAN FRANCISCO: A federal judge on Thursday tossed out more than a dozen patent infringement claims filed against Microsoft by Google-owned Motorola Mobility.

US District Court Judge James Robart, in Microsoft's home state of Washington, sided with the software colossus, dismissing 13 claims of infringement on a trio of Motorola patents involving digital video encoding and decoding, according to court records.

The Motorola patents were evidently not specific enough regarding the computer code involved, according to the documents.

The decision significantly narrowed the case.

If the remaining claims survive a similar legal challenge, Microsoft would likely be entitled to pay a reasonable rate to license what is considered a "standards-essential" technology, according to intellectual property specialist Florian Mueller, of FossPatents.com.
