Last Friday, Cayman Islands-based Imperium Holdings filed a complaint against Apple, Kyocera, LG, Motorola, Nokia, RIM and Sony. The seven companies have been accused of violating five patents related to picture taking and processing on smartphones.
The lawsuit was filed last week in the U.S. District Court in the Eastern District of Texas, Tyler Division. Patent infringement suits are frequently filed in that jurisdiction, in hopes of a more favorable outcome.
The five patents named in the suit are:
- U.S. Patent No. 7,750,949: Automatic flicker frequency detection device and method
- U.S. Patent No. 6,838,651: High sensitivity snap shot CMOS image sensor
- U.S. Patent No. 6,838,715: CMOS image sensor arrangement with reduced pixel light shadowing
- U.S. Patent No. 7,064,768: Bad pixel correction while preserving features
- U.S. Patent No. 7,109,535: Semiconductor device for isolating a photodiode to reduce junction leakage
Specifically cited in Imperium's complaint in alleged violation of the patents is Apple's iPhone 3G. However, the lawsuit notes that the allegations are "not limited to" that device, released in 2008.
Imperium has asked the court for damages related to alleged infringement of the five patents in question. It also seeks a permanent injunction prohibiting Apple and the other six named companies from engaging in further alleged infringement of those patents.
