July 3, 2012 - Days after Apple's winning two injunctions against Samsung Android devices, Google was hit with another patent dispute: Nokia claims that the Nexus 7 tablet infringes some of its patents.

Nokia has yet to file a lawsuit, so it is unclear which patents are in question.

“Nokia has more than 40 licensees, mainly for its standards essential patent portfolio, including most of the mobile device manufacturers,” a Nokia spokesperson said to Wired. “Neither Google nor Asus [the manufacturer of the Nexus 7] is licensed under our patent portfolio. Companies who are not yet licensed under our standard essential patents should simply approach us and sign up for a license.”

BT is thus seeking triple damages for willful infringement as well as an injunction.

The lawsuit was filed in the U.S. District Court for the District of Delaware.

Groupon Sued for Patent Infringement

November 8, 2011 - A company called Hothand sued the popular daily-deal website Groupon for infringing a patent on a "subscription-based system for providing commerce information for one or more mobile devices for one or more merchants".

Keurig Brews Up a Patent Infringement Lawsuit over Knock-off "K-cups"

November 3, 2011 - Keurig, the company known for its single-serve coffeemakers, filed a patent infringement lawsuit against the Rogers Family Co. alleging that the latter's OneCup product infringes two Keurig patents.

Keurig claims that Rogers is violating the two patents by selling single-serving containers, called OneCup and sold under the company's San Francisco Bay brand, that work with Keurig machines and are much less expensive than K-cups. Furthermore, the plaintiff alleges that Rogers is liable for the acts of patent infringement committed by end users who brew up the Rogers coffee in Keurig coffeemakers.

This lawsuit follows a trademark infringement suit filed last month in which Keurig and Wolfgang Puck were sued over their "Jamaica Me Crazy" coffee. Flavor Dynamics, a New Jersey-based coffee company, says the Keurig product infringes its trademark on "Jamaican Me Crazy" coffee.

Flavor Dynamics seeks $1 million in damages alone, and claims its reputation has been damaged by dissatisfied coffee drinkers who posted videos on YouTube giving their product bad reviews when the product they really mean to bash is the Keurig/Puck coffee.

Lodsys Lawsuit Drives App Developers Out of US Market; New Patent Lawsuit Filed

July 18, 2011 - A story in the Guardian reported that many app developers are withdrawing their products from the US versions of the Apple App Store and Google's Android Market because they fear being sued by companies such as Lodsys, which earlier this year launched a lawsuit against several developers of iPhone apps.

And in another blow for the app developer industry, a company from India - Kootol Software - announced that it has sent a notice of infringement to several companies, including Microsoft, Apple, Yahoo, Google, IBM, Research in Motion, LinkedIn, MySpace, Research in Motion and a number of other companies. Iconfactory, one of the app developers sued by Lodsys, is also in Kootol's sights.

In an unusual twist, however, Kootol doesn't claim infringement of an existing patent but of a patent application: U.S. patent application 11/995,343, "A Method and System for Communication, Advertising, Searching, Sharing and Dynamically Providing a Journal Feed." Kootol says it has also applied for patents in India, Canada and Europe.

Microsoft in Patent Infringement Lawsuit over Bing Maps

January 7, 2010 - Skyline Software Systems Inc., a Virginia company, has sued Microsoft for patent infringement, claiming that Microsoft's Bing mapping program is infringing its patented technology.

Skyline's patent, which issued in June 2009, relates to a way of sending 3D images over the Internet.

Microsoft's Bing is designed to compete with the very popular Google Maps, as Microsoft attempts to become more competitive in the search engine field. And Google itself has had a brush with Skyline over a different patent, though a federal judge in Boston ruled that there was no infringement.

Skyline makes terrain-visualization software that shows land masses in 3D on computers and handheld devices. Mostly used by government agencies, the software was used in the Sichuan province of China after the May 2008 earthquake to help with the relief effort.

Vizio Scores Win in Patent Infringement Lawsuit against Funai

June 22, 2009 - As reported on our Patent Infringement Litigation News page earlier this month, Vizio, Inc. had filed suit against rival Funai Electric Company, Inc. for infringement of patents related to high definition flat panel televisions. Funai sells HDTVs in the US under the brands of Emerson, Sylvania and Philips.

Vizio has now scored a win in its patent infringement lawsuit against Funai, as the International Trade Commission granted a temporary hold on a federal ban that would have prevented Vizio from importing certain HDTVs into the US based on the fact that they contain chips that were found to infringe on a Funai patent.

In addition, the U.S. Patent and Trademark Office recently re-examined Funai’s patent and concluded that its claims are invalid.

The ban would not have had much effect on Vizio anyway, however. “The products involved with this particular claim are obsolete and no longer in mass production,” the company said in a statement. The win is more significant in light of Vizio's ongoing antitrust litigation and the litigation over Funai's infringement of Vizio's patent.

Funai has also filed a patent infringement lawsuit against LG Electronics Inc., on June 5.
