“A method for allowing a number of wireless transceivers to exchange information (data, voice or video) with each other. A first frame of information is multiplexed over a number of wideband frequency bands at a first transceiver, and the information transmitted to a second transceiver. The information is received and processed at the second transceiver. The information is differentially encoded using phase shift keying. In addition, after a pre-selected time interval, the first transceiver may transmit again. During the preselected time interval, the second transceiver may exchange information with another transceiver in a time duplex fashion. The processing of the signal at the second transceiver may include estimating the phase differential of the transmitted signal and pre-distorting the transmitted signal. A transceiver includes an encoder for encoding information, a wideband frequency division multiplexer for multiplexing the information onto wideband frequency voice channels … ”
That’s patent the current US cassification for patents , 375/260; 375/219; 375/298; 375/E01.002; 380/34, filed by Michel Fattouche, and Hatim Zagloul.
“John Lindgren had a hard time keeping his mouth shut last week.
The “chief executive of Mosaid Technologies Inc. addressed analyst concerns over the Ottawa-based patent holding firm lacking a robust wireless portfolio during the company’s Aug. 25 earnings call, saying those claims were a “misperception.”
“Our achievements make clear that is just not the case,” Mr. Lindgren said then.
What Mr. Lindgren couldn’t talk about was a deal he was about to strike with Microsoft Corp. and Nokia Corp. that would give Mosaid control of 2,000 advanced cellular technology patents originally filed by the Finnish phone giant.
Announced on Thursday, the agreement catapults Mosaid into the most lucrative arena of patent warfare — and potentially culls a standing hostile takeover bid.
“The company is in the process of considering an unsolicited $480-million buyout offer made by rival Ottawa patent firm Wi-Lan Inc. last month, continues, the Financial Post.
“Also on last week’s Mosaid earnings call, a special committee of Mosaid’s board of directors called the offer “opportunistic” and said they would issue a formal response no later than September 7.
Now, “WiLAN, a company that holds a number of patents related to the wireless industry, has launched another patent infringement lawsuit against Apple, Hewlett-Packard, Dell, and other, says CNET News.
In June, 2004, Wi-LAN based in Calgary, Alberta, Took on Radiata Communications, a supplier of chipsets for high-speed wireless networks, saying the it’d infringed its Wideband Orthogonal Frequency Division Multiplexing (W-OFDM) patent.
“In November, 2000, Cisco bought Radiata, based in Australia, saying,’This acquisition strengthens Cisco’s New World strategy by expanding its ability to deliver next generation wireless networks using the IEEE 802.11a standard for faster data rates’.
Filed in the U.S. District Court for the Eastern District of Texas, Tyler Division, WiLAN’s suit alleges that the defendants, which also include HTC, Alcatel-Lucent, and Sierra Wireless, violate patent RE37,802, which relates to CDMA and HSPA communications, as well as patent 5,282,222, related to Wi-Fi and LTE.
According to a p2pnet post, “Cisco’s Linksys Division and Aironet product line utilize advanced OFDM technology which, says Wi-LAN, infringe on its Canadian patent 2,064,975 and US patents No. 5,282,222 and 5,555,268.
’s our intent to collect, either directly or through component manufacturers, royalties from any company selling 802.11a, 802.11g or WiMAX Certified equipment.”
“This legal action against Cisco puts the industry on notice that Wi-LAN will aggressively protect its patent rights,” said ceo and president Sayed-Amr (Sisso) El HamamsyAt the time, adding, “Wi-LAN has consistently maintained that its patents are necessary for the implementation of the 2nd Generation WiFi Alliance standards, IEEE 802.11a and 802.11g, and the WiMAX Forum standards, IEEE 802.16 and the ETSI BRAN HiperMAN.
Would Wi-LAN win the David and Goliath battle?
“We think we have a claim with merit,” company business develoment Andrew Apedoe told p2pnet.
