NTP, a patent-holding company best known for prying a settlement of more than US$600 million from the maker of the BlackBerry, is now suing the other big names in the smartphone industry: Apple, Google, Microsoft, HTC (宏達電), LG and Motorola.
The suits, filed late on Thursday afternoon in federal district court in Richmond, Virginia, charge that the cellphone e-mail systems of those companies are illegally using a patent owned by NTP.
The round of litigation against leaders in the smartphone hardware and software market is the latest step by NTP to assert that its intellectual property is the foundation of modern wireless e-mail systems and that major corporations are infringing with impunity.
Its critics have said that NTP has consistently inflated the importance of its innovations and that it is the very model of a patent troll, a company that produces no product or service other than licensing demands and lawsuits.
NTP and Research in Motion (RIM), the maker of the BlackBerry, fought in the courts for years, with NTP fending off most legal challenges.
Indeed, RIM settled with NTP in 2006, a few months after the US Supreme Court refused to hear the Canadian company’s appeal.
The US$612.5 million pact included a perpetual license for RIM to NTP’s technology.
The potential payday for NTP in the current litigation is uncertain. It could be as much as several hundred million US dollars, legal experts say.
But it could be far less because technology and product designs change quickly and recent smartphone e-mail systems may well have been designed with an eye toward avoiding NTP’s patents.
The companies named as defendants in the suits declined to comment.
But whatever the outcome in the latest suits, NTP has already altered the patent economy, legal experts say.
Big technology companies, they say, no longer ignore sizable patent clusters in their field, but go looking for them.
RIM, by contrast, first learned of the NTP infringement claim in a letter in 2000, when the Virginia company tried to persuade RIM to license its technology.
NTP was founded in 1992 by an engineer and inventor, Thomas Campana Jr, and Donald Stout, a lawyer.
Its initial patents grew out of work that Campana, who died in 2004, had done in 1990 for AT&T for relaying messages from a computer to a wireless device — a pager or a cellphone.
His collection of patented technology covers wireless e-mail and the design of radio antennas used on mobile devices.
He never did commercialize his technology, but the NTP claim is that despite all the work done by others in the field, Campana was indeed the creator of wireless e-mail.
And NTP, a private company owned by about 30 investors, is wielding those patents in its new lawsuits.
“Every infringer is now on notice,” Ron Epstein, counsel to NTP said. “They are going to have to deal with this instead of trying to wait it out.”
A few companies other than RIM have licensed NTP’s mobile e-mail patents, including Nokia and Good Technology, which expire in 2012.
In recent years, big companies have increasingly turned to patent-buying groups like Intellectual Ventures, RPX and Allied Security Trust, a nonprofit organization.
These groups essentially provide big companies with insurance against lawsuits on the patents they hold or license, in return for fees or investments.
The US Patent and Trademark Office also conducted a lengthy re-examination of NTP’s patents.
That process winnowed the company’s portfolio of legally valid patents.
CHIP WAR: The new restrictions are expected to cut off China’s access to Taiwan’s technologies, materials and equipment essential to building AI semiconductors Taiwan has blacklisted Huawei Technologies Co (華為) and Semiconductor Manufacturing International Corp (SMIC, 中芯), dealing another major blow to the two companies spearheading China’s efforts to develop cutting-edge artificial intelligence (AI) chip technologies. The Ministry of Economic Affairs’ International Trade Administration has included Huawei, SMIC and several of their subsidiaries in an update of its so-called strategic high-tech commodities entity list, the latest version on its Web site showed on Saturday. It did not publicly announce the change. Other entities on the list include organizations such as the Taliban and al-Qaeda, as well as companies in China, Iran and elsewhere. Local companies need
CRITICISM: It is generally accepted that the Straits Forum is a CCP ‘united front’ platform, and anyone attending should maintain Taiwan’s dignity, the council said The Mainland Affairs Council (MAC) yesterday said it deeply regrets that former president Ma Ying-jeou (馬英九) echoed the Chinese Communist Party’s (CCP) “one China” principle and “united front” tactics by telling the Straits Forum that Taiwanese yearn for both sides of the Taiwan Strait to move toward “peace” and “integration.” The 17th annual Straits Forum yesterday opened in Xiamen, China, and while the Chinese Nationalist Party’s (KMT) local government heads were absent for the first time in 17 years, Ma attended the forum as “former KMT chairperson” and met with Chinese People’s Political Consultative Conference Chairman Wang Huning (王滬寧).

CROSS-STRAIT: The MAC said it barred the Chinese officials from attending an event, because they failed to provide guarantees that Taiwan would be treated with respect The Mainland Affairs Council (MAC) on Friday night defended its decision to bar Chinese officials and tourism representatives from attending a tourism event in Taipei next month, citing the unsafe conditions for Taiwanese in China. The Taipei International Summer Travel Expo, organized by the Taiwan Tourism Exchange Association, is to run from July 18 to 21. China’s Taiwan Affairs Office spokeswoman Zhu Fenglian (朱鳳蓮) on Friday said that representatives from China’s travel industry were excluded from the expo. The Democratic Progressive Party government is obstructing cross-strait tourism exchange in a vain attempt to ignore the mainstream support for peaceful development
DEFENSE: The US would assist Taiwan in developing a new command and control system, and it would be based on the US-made Link-22, a senior official said The Ministry of National Defense is to propose a special budget to replace the military’s currently fielded command and control system, bolster defensive resilience and acquire more attack drones, a senior defense official said yesterday. The budget would be presented to the legislature in August, the source said on condition of anonymity. Taiwan’s decade-old Syun An (迅安, “Swift Security”) command and control system is a derivative of Lockheed Martin’s Link-16 developed under Washington’s auspices, they said. The Syun An system is difficult to operate, increasingly obsolete and has unresolved problems related to integrating disparate tactical data across the three branches of the military,
