SAN JOSE -- Both Atmel Corp. and Silicon Storage Technology Inc. issued statements this week regarding the status of litigation between the two companies.
Earlier in the week, SST reported that U.S. International Trade Commission Judge Paul J. Luckern ruled that U.S. patent 4,451,903 asserted against SST by Atmel was invalid.
In July 1999, the ITC determined that the patent at issue, U.S. patent 4,451,903 which Atmel acquired from Seeq Technology Inc. in 1994, was unenforceable because it did not name all of the actual inventors. Atmel then petitioned the U.S. Patent and Trademark Office to addanother Atmel employee to the patent and appealed the decision.
However, the judge found that the patent, as amended, still fails to list the proper inventors, according to SST, of Sunnyvale, Calif.
Atmel's director of litigation and intellectual property counsel, Julie Mar-Spinola, noted that the ALJ ruling that the corrected '903 patent is unenforceable is not the final word on this issue. The findings are not final until adopted by the ITC commissioners.
"Atmel strongly believes that this initial determination is unwarranted both on the facts and the law, and expects to file a petition seeking review by the Commission on May 30, 2000," Mar-Spinola said.
Atmel also reported that it expects the commission to make a ruling this summer regarding Atmel's claim that U.S. Patent No. 4,511,811 for a "Charge Pump for Providing Programming Voltage to the Word Lines in a Semiconductor Memory Array" was infringed by SST, among others.
