The complaint, filed Feb. 22 in federal court in Charlotte, North Carolina, claims Sumitomo is infringing patent 6,432,586, which was issued in 2002 and covers a separator in high-energy rechargeable batteries. The separators prevent short circuits that can reduce efficiency and limit safety problems from overheating.
Sumitomo Chemical makes the chemicals and materials for lithium ion batteries that use Celgard’s invention without permission, according to the complaint. The separators are used in batteries made by Panasonic Corp. (6752) for laptop computers, Celgard said in the suit.
“Celgard has a long history of innovation in lithium-ion battery separators and is a world leader in this technology,” Polypore Chief Executive Officer Robert Toth said in a statement. “We have a responsibility to our customers, partners, and shareholders to safeguard the investments we make in innovation.”
Tokyo-based Sumitomo Chemical has filed a trademark application to use the name “Pervio” for its separators, according to the complaint.
Polypore is seeking a court ruling that prevents the future use of the invention, plus cash compensation.
Polypore, based in Charlotte, also makes Duralife automotive batteries, and separators for health-care products like hemodialysis machines and beverage filtration machines. Weakness in the end market for electronic devices and electric vehicles were blamed for a 4 percent drop in fourth-quarter sales to $180.2 million, Polypore said Feb. 20.
The case is Celgard LLC v. Sumitomo Chemical Co., 13cv122, U.S. District Court, Western District of North Carolina (Charlotte).
Reckitt Benckiser Faces Generic Threats After FDA Rejection [bn:WBTKR=RB/:LN]
Reckitt Benckiser Group Plc (RB/)  faces competition in pharmaceuticals for the first time after the U.S. Food and Drug Administration approved two generic variants of its Suboxone heroin-dependency drug, thwarting the company’s attempts to keep rivals away from its most profitable business.
The company said yesterday that two manufacturers have FDA approval to produce generic Suboxone tablets in the U.S. Competition could arrive within a month, according to Alex Howson, an analyst at Jefferies International in London.
Reckitt Benckiser was also hurt by the FDA’s rejection in a Feb. 22 letter of the company’s September petition asking that makers of similar medicines implement more safeguards. The FDA also asked the Federal Trade Commission to look into claims by generic drug makers of anti-competitive business practices on Reckitt Benckiser’s part.
The shadow of competition to Suboxone has hung over the Slough, England-based company since it lost U.S. patent protection in 2009. The pharmaceuticals unit generated 21 percent of profit last year, and analysts yesterday reduced their 2013 profit estimates by as much as 4 percent.
Reckitt Benckiser, which said it was “disappointed” by the rejection of its petition, has said generics would eliminate as much as 90 percent of tablet sales and up to 20 percent of the newer film-strip version, which dissolves under the tongue and has captured a 64 percent volume share in the U.S.
One of the generics will come from Bridgewater, New Jersey- based Amneal Pharmaceuticals LLC, which said in a statement yesterday that is has received FDA approval for a generic version of Suboxone tablets, to be available in March. The other will be made by Actavis Inc. (ACT) of Parsippany, New Jersey, which said in a statement it intends to begin shipping its product immediately.
Reckitt Benckiser said it’s sticking with its decision to stop producing Suboxone in tablet form next month as it weans patients onto the film-strip version, which it unveiled in 2010.
Sony Applies for Patent on Load Time-Based Anti-Piracy Measure
Sony Corp., maker of the PlayStation video game console, is seeking a patent on a technology aimed at detecting pirated games.
According to application 20130047267, published in the database of the U.S. Patent and Trademark Office Feb. 21, devices using this patented technology will be able to identify whether a game is legitimate based on the amount of time it takes to load into the device.
This will detect whether the game -- or other content -- is “illegally transferred or pirated to another, unauthorized media type.” Sony said that despite the use of digital rights management software and tamper-resistant hardware, pirates are able to reverse-engineer such technology and circumvent the protections.
Using this technology, a device will have a threshold of load time for legitimate content. If the media doesn’t pass the validation in terms of load time, the user would be unable to access the content, Sony said in its application.
Tokyo-based Sony filed the application in August 2011.

Google’s YouTube Tells Nascar It’s Unblocking Fan’s Crash Video
Following a copyright infringement claim from the National Association for Stock Car Auto Racing, Google Inc.’s YouTube video-sharing service blocked and then unblocked a race fan’s video of the crash at the Feb. 23 Daytona 500 race, the Washington Post reported.
Nascar asked for the removal of the video “out of respect for those injured,” the race company said in a statement, according to the Post report.
YouTube then put the video back up, saying “Our partners and users do not have the right to take down videos from YouTube unless they contain content which is copyright infringing, which is why we have reinstated the videos,” according to the Post.
The fan’s video shows a race-car wheel that ended up in the stands, with race viewers waving for help, the Post reported.

‘Major’ German Companies Hit With Cyber Attacks, Official Says
Stefan Keller, the head of the German Interior Ministry’s department in charge of cyber security, told the European Police Conference that 70 percent of all major Germany companies “are threatened or affected” by cyber attacks, Der Spiegel reported.
The “overwhelming number” of attacks targeting German government agencies are coming from China, mainly Beijing, Shanghai and Guangzhou, according to Der Spiegel.
Proposed German legislation may contain a requirement for companies that are targets of cyber attacks to report them to the government, the newspaper reported.
Presently, “it is a question of coincidence” that the government learns about attacks against German companies, Der Spiegel reported.
